Yep, 10k oil changes suck, but there is NO WAY you'll get that level of deposits... MAYBE if they are using dirt cheap 30wt non detergent lawnmower oil, but that looks more like someone was ripped off for services not performed and had a couple 20k+ changes due to a shop lying.
I think you are right. 10,000 mi (16,000 km), is a long interval, especially on cheap oil, but this is a helluva bigger interval than that! That’s why, if you have the oil changed, check the dipstick immediately after. It will be easy to tell if the oil was actually changed or not! Also look at the oil filter. If they use the same brand, but a mark on the old one, or ask to have the old one shown to you.
@@lukek1949when I was a mechanic 30 years ago I worked at a VW Audi dealership for some time, and Landrover Jaguar later on. Almost all european cars had 15kkm (10kmi) intervals back then and they often have 30kkm (20kmi) intervals these days. The engines were and are spotless unless something was broken, such as a head gasket leaking combustion gas into the crank case. This is a petrol engine, the oil should be dark brown, not black after 10kmi. There really are only two ways an engine can look like that: either a) a piston ring, head gasket turbo charger or similar is broken or b) the oil was never changed for at least 50kmi. Tho I wonder how in the later case the oil filter isn't completely filled with crap and still allows oil through.
@@elcano9l52 listen again, they have the carfax report showing the oil was changed every 10,000 miles all they say is they don't know which place did it.
I've been a tech 50 years and remote starting, idling in traffic, and other slow driving uses can look like this in 75k miles on honda, toyota, and others seemingly at low risk of sludge.
I have a 2015 3cyl fiesta and did 10-20k oil changes and just took the valve cover off at 400k and it’s beautiful with very little wear on my cam profiles and no sludge whatsoever. I believe a lot of the issue is massive idling times and short trips with no warmup.
Well first I want to apologize for my ignorance because I thought the oil was being change every night since it’s looks so oily. Can you explain how oil changes are on a vehicle and how what’s in the video supposed to look like?
@@davidponce6132 oil changes are recommended to be changed every 6 months or every 5000km or 3000 miles. In this video, this doesn't seem like the oil is even ever changed.
It looks like 10k. 5k is the recommended, 3k if you have vvt gasoline, because fouling the vvt filter or solenoid will destroy your engine really quickly
@@konradbrochocki4923 not really! The synthetic oils can go that long and we have been using them for quite a long time and our vehicles have never looked like this! Just had a similar job done on my suv and it wasn’t anything like this! Def more to this story, like faked records and no changes done, ever!
@@theshadowbehindyou9631 It's exactly what I'd expect from some dealers or quick-lubes doing the oil changes. Because many of those places will use the absolute lowest tier oils on the market, sold as if they're top-shelf full-synthetic.
I have a service business with 4 trucks and every one of them use synthetic oil with 10,000 miles between oil changes. In 20 years of my business they have NEVER had an issue with the engine
Thats what ive done w my lightning. Change the oil filter, every 3-5k. Correction. I used to aggressively drive him, still kinda low miles. Past few years i maybe had to change the oil on a yearly basis. 500 miles/yr tops. My beater car also.
I've been trying to learn cars my whole life, glad you're saying this with a lot of Likes...was my understanding synthetic, if anything, would prevent, not cause, something like this.
@@PaPaWizdomyeh this video is complete BS that engine has had very few to no oil changes and as you've said synthetic oils are far superior to mineral oils 3k mile oil changes are a thing of the past here in Europe 10-20k mile oil changes have been standard for years
The “dealership” oil changes have not been happening then.. this is not normal and it’s very apparent that at 86k if this is what your car looks like… you need a new mechanic. And a lawyer.
@@davidhenningson4782 Yes they can but...a mechanic recommending 5000k changes when the manufacturer says 10,000k is a smart mechanic. That's a mechanic that knows 10,000ks is WAY past an oil's lifespan of heat cycles and ability to lubricate. Whether synthetic or real "dino" oil, it has a lifespan. It breaks down over time and that time is long before 10,000ks. That's a mechanic that's recommending a very inexpensive way of keeping their customer's vehicle operating efficiently and preventing very expensive damage.
I've seen at least one major oil brand say that they don't recommend turbo charged cars to go that long. They usually point to manufacturer recommendations first or less than 7k ish miles.
Yes but I think what they're trying to say is that even if you did 10,000 mi oil changes it would not look anywhere near that bad Yes the oil would be dark and you could have where happening but to see an accumulation like that I venture to say there's probably depending on driving habits and style I at least know with my driving habits that's got to be every bit of 30,000 miles on that oil
You got it. I'm 76 years old and still crawl under my wifes CRV and my Silverado to do oil changes. Only way I can feel confident it was done correctly or done at all. I also do my John Deere 500 series lawn tractor and my Harley. Full synthetic in everything and the valvetrains are slick as glass. I bought a new Mustang GT 5.0 liter in 1986 and gave it to my son after I had my fun with it. Put in nothing but synthetic after initial break-in and he continued the practice. He recently pulled the valve cover and oil pan gaskets for replacement and at almost 40 years old and 70,000 miles the motor was spotless. If you want it done and done right and you have the time and know how.....do it yourself.
I font trust dealerships for oil change, I use an independent garage I trust, I take my car a day before, drain the old oil overnight to drain maximum if not all, put new oil in, in the morning with new filters etc, car drives like brand new 😊
For real man I straight up hate the dealer I caught them pretending to do a service on my new Tacoma those criminals. Petaluma Toyota in California are pretending to do services on vehicles.
@@mattjames5858 I had a Toyota van in for extended warranty service and they broke my instrument cluster bezel, my heat/air vents, and also my radio stopped working. They claimed that it was like that. They did fix everything except the AC vent which they insisted was broken and I was tired of arguing with them.
I have 100k on my car. Bought it brand new and got the oil changed every 10k by the dealer. After the last oil change, I used a borescope to do a visual inspection of the cams. It looked pristine. Just a nice healthy coating of thin oil film and clearly identifiable silver metal. No sludge whatsoever. That SUV never had the oil changed. He was getting scammed by whatever shop was pretending to do his service.
I'm getting close to 10k on my Lexus and the oil on the stick is hardly dark. The only way that's 10k and looking like that is if they were using the cheapest oil
You also need to factor in climate and driving habits. If you ask any real mechanic/technician, because I’m one, they’ll never recommend 10k intervals. On my personal cars 5k or 6 months max, whatever comes first.
They stated they have the car fax report that the oil was changed. The question is whether the company(s) actually did what they were supposed to do. This is why you learn to change your own oil if nothing else.
@@Methodical2I took my Kia soul to a valvoline quik lube place for an oil change and one of the kid techs put in the wrong oil filter. Technically they did the change! Just wrong! 😂
they said the vehicle had 87000 miles and they changed their only every 10000 miles. Slug can happen when oil breaks down. this means this vehicle has had atleast 8 oil changes.
yea exactly, saying that the interval should be changed to 5K miles is crazy, its clearly not been changed every 10K miles, i promise you oil that is changed EVERY 10K miles will NOT look like that!!
@@alansimmons9744 not a chance was that oil changed every 10K miles, not a chance.. Either customer is talking BS or the dealer is charging and NOT changing...

@@kloc4995 That's interesting. I'm really interested to know if any of those engines were running full synthetic oil with long-life filters - versus conventional oil and filters.
the comments section got it right - the oil changes weren't done, just paid for. how do these guys not realize that 10K oil changes don't do this? pretty embarrassing lack of awareness
As someone who bought such a car, I agree no oil change was done. My car had redflags of neglect but the dealer I bought from had polished the car to pristine condition I was easily tricked. Looking back, I realized how the previous owner never took care of anything
@@Clay-iu2ht Hi, I don't know/understand. Are they saying they don't or do suggest using synthetic for longer intervals? I always thought conventional (pun) oil was always shorter intervals. 🙂
They have no clue what brand of oil, what type of oil, and don’t know who has been servicing it. Yet making assumptions it’s 10k intervals that did that 🤦♂️ I’d say someone has been falsely reporting the oil changes and it’s possible it’s hardly or even never been changed.
That is 100% not the condition of engine oil at a 10k mile interval service that is being done regularly. That oil has not been changed for much longer.
@@Task-Failed-SucessfullyI don’t know what sort of oil you use in the US, I only have an oil change every 10,000 miles or a year here in the UK. This is the specified interval for most cars in the UK. I have had cars that I did 30k+ miles a year in and they were still going strong at well over 250,000 miles.
Scientific tests have shown good correct spec oil is not worth changing before 8000 miles there is no benefit 8 to 10000 is perfect or a year whatever comes first.

Or just change your own oil lol. Can do it in an auto parts store parking lot even lol. It’s not very hard to change oil, but people are lazy.. and thus this is what happens. I currently have two Toyotas, a Ram and a BMW and always change my own oil. Not hard and it’s like a 30 minute job and much of that time is just chilling while the oil drains out lol. Takes longer to get my tools out and get the vehicle on ramps, than to actually change the oil. Don’t be lazy, folks!
Absolutely. I took Tahoe to a big dealer in Florida for a “one hour” oil change. Short story it became a f&@king nightmare! They’re simply criminal enterprises preying on the clueless people when Nothing about cars! Disgusting.
@@Goriaas Project Farm did a good study on this That aside, 5-8k miles is honestly too frequently for oil in the modern era. Top it off from time to time(ya really should check it regularly anyway) then change it and the filter(some dealerships, like Honda, don't do that apparently) when it's too dark. The main thing is go for a decent brand, because the filter's going to hide a lot of the actual damage being done, damage that no amount of changing frequency will matter for.
@@InfernosReaper nissan recommends every 20k km (which is about 13k mi) for my car and it has been done like that from the previous owners. still works well and has no sludge after 170k km what did the study actually recommend? now i m curious
I’ve seen plenty of vehicles with 10k oil changes and thats not one of them. Thats more like 30k. 10k and the oil is just super dark with minor sludge. That oil is carboned up.
That's a turbo engine and they probably used conventional oil in it to be honest! That's what happens in those turbo engines when they use the wrong oil and usually the wrong oil weight too.
I have seen quite a few gm 3.6L engines like this. Mainly in the GMC Acadia suv. 2008 ish model years called for conventional oil. Customers told to change oil by the oil life monitor, 6000-8000 miles. Same yr, same engine in a Cad CTS called for synthetic. Almost never had that issue in the Cadillac
@kevinkalivoda3442 oil brand matters. Valvoline is the first manufacturer of vehicle oil from aviation. They are the only company that runs a new synthetic that can completely clean your engine with their additives. I'm not even sure it's available yet but it's 0 weight. It's still probably way too thin for VVT sensors and crank sensors. Some of that stuff throws codes. I had a jeep compass running thin synthetic oil and it starved the vvt sensor which threw off the timing in the crank and required a teardown.
Owned a 2004 Toyota Camry with nearly 400,00 miles. Changed the oil every 9-10k. Used either Mobil1, Castrol or AMSoil full synthetic. After 15 years the car's interior began to dry rot; no problems with the engine. THIS is maintenance neglect NOT a lack of oil changes.
Right, I had two 74' pontiac Grand Prix SJ 455s, in the good old days, always used Mobile1, changed the oil when needed. Always never anything but a great running great ride on Wide Ovals! The memories keep me spoiled from what folks settle for since then.
Yes, I use Amsoil too and always run their Engine and Transmission Flush in the old oil just before drain and change. Doing this cleans the slots in the pistons where the rings ride and move during piston movement and it cleans the very small area between the crankshaft and the connecting rod bearings.

@@kloc4995 I'm a tech too. Is there any way to confirm that the engine oil those customers used was always the "Advanced" Full Synthetic 20,000 mile oil used with the complimenting 20,000 mile oil filter? Because that's the only way you can push oil changes to 10,000 miles. Regular full synthetic is only rated at 10,000 mi, so the oil change intervals should be 5,000 miles for that oil & filter.
And the vast majority of people that buy Land Rovers are wealthy because Land Rovers are expensive and they are not concerned about maintaining a vehicle because they have so much money they just go buy a new vehicle when it breaks down
Yep, what I was thinking. The comments say it all, why would there be all that sludge from too MANY oil changes makes 0 sense. Can't believe they're mechanics.
No synthetic oil turns to sludge in 10,000 miles, especially in a 2L inline 4 motor in a SUV, physically impossible as the engine isn’t working nearly hard enough for long enough to create such extreme forms of oxidation. This is the typical case of the dealer saying they changed the oil when they clearly never did. 87,000 miles later the factory oil ends up looking like forbidden brownie batter.
@@plowe6751 Besides of very rare situations where they actually don't have a dipsticks, oil in diesel engines turn dark after fiew kilometers. You cannot tell if oil is fresh.
Yep…I don’t believe him either, which makes me want to put these guys in the same list as the shop or mechanic that was “doing the oil changes “ for this car. 🤔
I'm wondering about that comment as well....is it possible that he was inferring that they must've been using synthetic because if they had been using conventional ,it wouldn't have made it that long?.idk
I was given 2 free oil changes from the dealership when I bought a brand new vehicle. I brought it in at the 3k mile mark as they advised and handed my keys to the mechanic and he said have a seat in waiting rm it will be around 30 minutes. As im sitting there I look into the service area and theres a break room table there and i can see in the mirror...he is eating a sandwich and flipping through a newspaper. After 25 minutes of this he gets up..puts his sandwich wrapper in the trash can..wipes his mouth and comes out to the service counter and says.. Ok shes all done. I asked him...who did the oil change and he says...I did. I called the manager and he said that he will talk to the mechanic and investigate then give me a call. NEVER got a call back and went i showed up at the dealership they said both of them were on 3 week vacation. As i left the building i looked over at the service area and.....that mirror was removed. I change my own oil now.
I came here to say this. It looks good for the video I suppose, but if you actually change the oil every 10k miles it would never look like this. Also, what's their beef with Synthetic oil?
I think it’s a combo of getting fleeced, and what happens when you believe that garbage they are telling you at every 10k, 0W oil teeny tiny passages and a high heat turbo motor all seam like a recipe for this.
That car hasn’t had 10000 mile oil services…. 10,000 is fine but the key is you actually need to change the oil rather than just stamping the book and charging the customer.
its wild that some dealership would simply not do the requested work (which honestly dont take long) and rather gamble that someone wouldnt be sueing them
Driving habits have a lot to do with it, too. If it takes you 2 years to put 10,000 miles on a car, it’s from short trips, stop and go traffic, etc. The engine will rarely get up to operating temps for any significant period of time, and cannot evaporate condensation and fuel dilution. It is also considered to be extreme conditions by all manufacturers, meaning the time between oil changes should also determine intervals, not just mileage.
If the temp gauge ain’t in the middle the engine ain’t warmed up enough which means you risk condensation inside the engine which leads to build up of carbon dirt and nasty oil. Also the cat won’t ever get warm enough to work properly and don’t forget transmission temp as well. You need to drive the car more than 5 minutes and most people only drive for 5 minutes to work. A fully warmed up car works at its best then when it’s cold.
Whatever dealer they've been going to needs investigating immediately because that engine has clearly not had an oil change since it was new!!! SCAM DEALERSHIP! Name and SHAME...
As a young mechanic 40 years ago I saw a neighbor girl trash her 1975 Chevy Luv small pickup truck (really a Japanese Izusu). She was just adding oil & NEVER changing it & it was conventional non-synthetic oil. At about 5 years & 60,000 she had stalling / no start complaints. We pulled the oil cap & crusty residue was popping up & out We pulled the valve cover & it was like a rounded bundt cake pan mold - the arch of crust read "Izusu" as if molded ! NASTY !!! We had to chip away with a flat screwdriver to remove the mess. Of course it never ran well after & engine was TOAST due to the extreme neglect. This Land Rover pictured isn't anywhere near as bad, but it's bad enough. I'd say the shop scammed the owner by using cheap non-synthetic oil & skipped 2 of 3 "changes, etc. No way it was Synthetic OR changed regularly !
@@joeg5414 Very possible ! But we can only surmise. In the case I mentioned in my comment the neglectful neighbor girl had lost her father & was pretty clueless about the necessity of oil changes. I made it a point to teach my 4 daughters about it's importance but only my Son climbed under the car to learn how exactly. Pretty typical lol !
480k on my Cummins with 10-15k mi oil changes. Still clean under the valve cover. You guys should be embarrassed to blame that on 10k mi oil change intervals. You guys are the reason why mechanic shops have a bad reputation. You guys think everybody is stupid.
Yeah, they're talking out their butts. I've never seen anything that bad. I had a car that went 30,000 miles between changes, I opened it up at 120,000 miles and it was clean as a whistle, not one carbonized deposit, everything was still in spec. And I ran it hard. Mobil One. Maybe this range Rover only got driven a mile or two at a time and didn't get hot. That's my guess.
Here in the UK we are 18000 mile oil change intervals and don't see concerns like this, i think this vehicle has covered far more miles than stated between oil changes.
Oil in US is not the same. Neither is fuel. I worked corporate for a Euro mfr and HQ was always surprised at oil related issues (like stuck rings) that US division had with 10k interval that Europe saw near zero of with 12k and 15k intervals. I am talking miles, not km
My uncle told me this. A friend of his bought a "little old ladies car". It was very clean, 11,000 miles, 15 years old. She only drove it two miles to the store once a week. and every so often to get her hair styled. It never got fully warmed up. She was selling it to buy a smaller car easier to park. She told him it was due for oil change at 12000 miles. She told the guy to just drive through town and come right back. The car ran great. He bought it. When he drove it home, it would not go faster than 40. At home he checked the oil, it was full, but it was black. He forgot to check it, he was so excited to see how clean it was. He removed the drain plug but nothing came out. He knew it was full, so he poked the drain hole with a screwdriver and the oil came out, but slow. He removed the valve cover and it was really sludged up. He called a trusted mechanic and asked what to do. The old mechanic said, "Put the valve cover back on, install the drain plug. Fill it to the hole with kerosene. Remove spark plugs and give generous amount of STP gas treatment to each cylinder. Let it sit for a whole week. Drain the kerosene. Fill with one quart transmission fluid one pint Marvel mystery oil, and top it off with regular oil Add another pint to the gas tank. Remove spark plugs and crank engine to spit out the STP. Install new spark plugs and start it. Drive it 500 miles, change oil and repeat. But this time drive 1000 miles before changing oil. The car should be running better. Then Change oil and drive 3000 miles. Remove valve cover and see what happened. The guy was stunned. With each oil change the engine ran better until it could cruise at 65 with no trouble. Inside the valve cover it was clean as could be.
The dealership that was doing my oil changes didn’t change the oil. It went out on me right after the warranty expired. Their solution was to buy another car
I agree with everyone else: I've been changing every 10k on a variety of different vehicle with synthetics for several decades. None of my engines ever looked like that.
Don’t assume that every engine can handle a 10k oil change interval. Some engines, by their design, are “dirtier” than others. For example, small 4 cylinder turbo charged, direct injection motors tend be “dirtier” than large, naturally aspirated motors.
@@logancudd7030you have a good point. Back in the 1980s my partner bought a 1969 340 Dodge Dart GTS all original was only 40,000 MI from an old lady like that who only drove it a couple blocks within the neighborhood. I had an identical 69 340 Dodge Dart Swinger with almost 140,000 Mi on it, also all original never been apart. We raced each other, and for several weeks I would blow the 40,000-mile GTS away, it was so sludged up and would blow smoke at full throttle. After several oil changes and getting on it everywhere we went, the thing finally cleaned up and cleared out and was pretty close to the same as my car. I sure wish I still had both of those
@@ouroesa. Yes. And way slower to burn and turn to hard varnish. If I had a bearing that was only getting a tenth of the oil flow that it was supposed to get, I would want the oil to be a synthetic. I might have such a situation and not know it. I don't want a failure from such a situation.
I'm sorry, but that isn't a car with 87k miles with oil changes every 10k. Going 5k is ridiculous and scaremongering. There is something wrong with that engine, likely didn't have oil changes.
Oil changes not to long ago were done, at the most 6000 miles. Actually these long intervals between changes is new. One of the most common issues with engines today is oil breaking down before the mileage is reached for an oil change.
What are you talking about?! 5k is pretty normal. 10K is beyond the effective life of most regular oil filters. Ridiculous and Scaremongering, err no, perhaps you're justifying why you aren't changing your oil on the right interval?
@@2steaksandwiches665 I often go to the local Valvoline place as well. They get very busy sometimes, but if I see they have less than 4 cars in line in front of me I will wait it out. Once you get in there, the oil change on my car takes 19 minutes or less and I am on my way. I have a 15% off coupon that expires tomorrow, and with the coupon they are slightly cheaper than my go to mechanic shop and less time involved.
@@GMC.Sonoma.4.3 I only have them do my oil change, so the filter and the oil. But it’s worth it because I’m particular on the oil. The manager recommended it to me because he goes. We’re never gonna have that in stock.
Lots of comments here about 'that's never been changed' i can assure you it has. Friend of mine is a professional independent car mechanic (unit next to mine, i do bikes) and he had a Dacia owned by an old boy come in making a ticking noise in the head. It had 35,000 miles on it, in that time he had never taken it for a service or visited a dealership. The motor was written off, pulling the rocker cover off left a perfectly molded solid mass cast of the space inside the rocker box. Oil does not last 35000 miles, let alone 87000 miles. Repeated 10,000 mile oil changes would absolutely cause a build up like this based on that.
This is disgraceful. The dealership or whoever claimed to have been doing the oil changes was ripping off the owner of this vehicle. It seems to be obvious to everyone except the mechanics in this video that the oil changes weren't done at all. 🙄
Some cars are more prone to sludge and oil build up than others like this one, Yeah I’m sure that car went passed 10k without service. That doesn’t mean there not real mechanics, and definitely shouldn’t be insulated for trying to spread awareness to everyone & be helpful. The message was don’t wait 10k for oil service or this could be you, they got there point across.
I was a dealer tech for ten years. Every single engine I have ever opened up that called for 7-10k intervals looked like this. Manufacturers stretch intervals to lower "cost of ownership" numbers. Never pass 5k intervals. Fafo.
That dealership is basically trying to destroy that Land Rover so the customer can buy a new Rover so the dealership can stay in business. No way that oil has been changed even at 10,000 miles. That's only 8 visits.
Who can afford a new car every 2-3 years. Worst business model ever, won't work. This isn't a scummy business technique, it's just lazy mechanics or a customer who has not been servicing their car
Or the customer lied and has never changed the oil. “Oh I’ve done it every 9-10k” with no paper trail doesn’t sound like someone who is very diligent about taking care of their car.
NO. MOST MODERN OILS ARE GOOD ENOUGH..THIS IS FROM OIL BREAKING DOWN DUE TO WAY TOO LONG OIL CHANGE INTERVALS..(DIRECT INJECTION WITHOUT PORT FUEL INJECTION) FUEL DILUTION, OXIDATION, ETC.. NO MATTER WHAT OIL YOU PUT IN IT, ITS NOT GOING TO LOOK MUCH DIFFERENT EVEN IF YOUR USING THE BEST OIL FOR THE SPECIFIC ENGINE..OIL CHANGE INTERVALS ARE THE PRIMARY CULPRIT !!!! 5000 MILES FOR N/A ENGINES AND BOOSTED APPLICATIONS NEED IT SOONER THAN 5K PREFERABLY!!
Not really the oil. Filtration is what is junk on automobiles. Most oils are decent enough quality they can go 10k, it's the filtration that gets you in the end. That said, this vehicle has been severely neglected. This oil as never been changed likely.
Just because the last oil change guys told Car Fax they changed the oil, does not mean they changed the oil. NO WAY that is 10k interval. Looks more like 80k interval.
Every time you change your oil, first mix a full can of Seafoam into it for about 100 miles. It is designed to break down and clean out all that sludge so it exits with the old oil. The oil hasn't been genuinely changed unless this is done.
I use Amsoil in all my engines. Signature series for my vehicles. I change the filter at 15,000 I drive another 10,000 and change both filter and oil. Yeah I is. 110 bucks but the quality is there and it is once a year. Plenty of quality motor oils out there don’t get me wrong. Filter changes are a must.I drive a 07 Buick lacrosse and have been doing this 9 years now with no engine issues. Don’t be a cheap ass when it comes to oil and filter,it will bite you in the long run.
This is silly. That motor is not representative of most Euro cars that specify 10k mi oil intervals. I've put HUNDREDS of thousands of miles on multiple cars (Audi, BMW, Mercedes) and NONE of them have had a single oil related issue.
I work at a JLR specialist and never come across this with regularly serviced cars, that's either not been serviced for a long long time or it's got the wrong oil in it.
I agree with the comments section. That's a "synthetic never breaks down so charge the customer but don't change the oil" oil change. I change my own oil and I still do it every 3k even though I know its no longer necessary because I have been scammed so many times by dealerships its maddening. Like how are they not being arrested. Everytime I have taken a vehicle in for any kind of major service every mechanic has always pulled me aside and asked me why my engine is so clean. I change the oil every 3-4k and I use those STP octane boosters, not for the horsepower but the cleaning effect they have.
Brian Murphy of Chicago went over a million miles in a 2007 Nissan Frontier changing the oil every 10,000 miles. It's documented on the TFL channel on RU-vid. I personally don't wait 10,000 miles to change mine, but just saying - the man went 10,000 miles between oil changes and the truck lasted over a million miles.
Dealers don't always use their own product. I found this out when I was looking for power steering ATF fluids for my Toyota. The parts guy said they just buy stuff from the local parts store. The Care Care Nut mentioned this in one of his videos and that confirmed it.

@@X85283 Yeah, but you notice Toyota products, including ATF, oil etc always says on the packaging, in this case ATF, that the product was made specifically for/to Toyota specifications as if theirs something magical in the bottle only for their vehicles, yet they will use what they can get on the shelf of a parts store.
@@Methodical2 So? It is still the spec that matters, not the marketing line they put on the sticker that goes on a jug of off the shelf fluid that meets the spec. If a Toyota really needed something special, they would define a new API specification for it. This has been done many many times before by car manufacturers (coolant and ATF types especially).
I really don't get it. I have a 2008 Sprinter van as the workhorse for my workshop. It is totally original. No EGR delete, no DPF delete. I change the oil according to the built in dynamic service indicator. The interval is always somewhere around 25,000-30,000 kilometers. The Sprinter has about 450,000km on the odometer now and the engine is absolutely clean inside. No sludge whatsoever. What am I doing wrong?
@@X85283 it is also used as a Diesel should be used. I very rarely drive less than 20 miles in one go. I recently repaired a leaking valve cover gasket on an Audi A6 with more than 500,000 km. When I removed the intake piping and manifold, it was, of course, coated with some black goo; but no hard crusts or chunks at all. I really don't like all that emissions crap; please don't get me wrong; but if you use your vehicle like you're supposed to use it (a big diesel engine is DEFINITELY not made for short distance city driving!!), it will last a long time.
@@lonniebeal6032what the hell are you even saying ? It’s supposed to have a particular viscosity . It’s not a one size fits all kind of thing dude . “ conventional “ my arse . Have you seen the recycled sludge they call oil & pass off as the word “ conventional “ ? Have you ever looked at it ? It’s repulsive .
What I find really amazing is how oil has reduced in specifications. In 1970's oil changes lasted 9K to 15K miles, no synthetics available. Now, every 3K miles with synthetics rated for double standard oil. Interesting maintenance concept.
They don't actually make that much money off of the oil changes, it's more about finding other issues in your car, of which you have the decision to get it repaired or not. If you go to a good shop, you won't have any problems. You should get your oil changed while it still looks and acts brand new which is 3000-5000 miles.
Yep, the amount of miles isn't as important (regarding engine wear, but does play a role in oil degradation) as the amount of start, stops and the time driven during operation. Frequent short trips without ever reaching operating temperature can cause this. Definitely want to change oil more often if your trips are short. Edit: Further context added for clarification.
@@therealjayseh No, I'm not. Oil can become sludge like that if it doesn't get to operating temperature because that's the temperature where unburnt fuel and water in the crankcase can evaporate/burn off. If you've ever used a catch can for time attack or drift, you'll see a similar substance begin to develop and accumulate at the bottom of the catch can when emptying it. Going a long time without changing your oil can do that, yes, but it is just one way that sludge like that can build up, there are other ways as well.
Oh; HUGE DIFFERENCE! Conventional oil is pretty much fossil fuel. When you bake conventional oil at high enough temperature temperatures for a prolonged amount of time it will sludge; Causing plaque on engine components; where on the other hand? Synthetic oil is made out of pure natural gas. Hence, the huge price difference. Synthetic oil does not sludge or cause plaque buildup, On the contrary, synthetic oil has a powerful cleaning agent as well as superior protection against friction…. Think of it as enzymes inside oil…. It’s that good. That’s why a lot of engine manufacturers Require (not recommend) The use of synthetic oils.
As a matter in fact; Synthetic oil is so good, that if you were to use it on a classic car (of course, using the correct oil weight); it has been known to cause all kinds of engine oil leaks seeping through every single gasket of the engine 😅 simply because the synthetic oil will immediately begin to break up all the engine gunk inside of the motor and gaskets…. So of course, you have to replace the oil pan, gaskets and head, gaskets and valve cover gaskets in order to give a new life to the car engine. It’s crazy.
Actually the truth is if you're using genuine fully synthetic oil and not doing any motorsports racing, you don't even need to change your oil at 10k. You can go longer until 15k-18k, even 20k depending on your driving situation. That sludge in the video shows that engine hasn't had an oil change throughout its lifetime.
