Lucas Fuel Treatment - One Year Update 

My 2017 Tacoma ALWAYS got 22 mpg I drive mainly open Highway. I used the Lucas and 2 fill ups later, I got over 24 mpg today.

Did not take into consideration the over treatment. Great job in catching that red flag. I have used Lucas for years , the difference in mileage for me is negligent 1 or 2 mpg per tank. Although the difference in using Shell gasoline to Wawa gasoline is around plus 10 mpg per tank when using Shell. My main reason for using Lucas is the injector cleaning capabilities and the upper cylinder lubrication which has helped me put 200,000 miles plus on two of my cars . The 2010 Hyundai sonata with the 4 cylinder has just developed a valve tick but that poor car was put through the wringer. My daily vehicle 130 miles per day round trip in Washington DC traffic for six years, loaned to my kids several times while their car's in the shop ( they're adults now , they can either marry someone who can work on cars or learn to do it themselves). I am done crawling under their cars because they heard a noise two months ago and decided to turn up the radio instead of fixing it.

Meticulous record keeping and analysis, as usual. Presentation perfect. Now, where’d I leave my keys.

I only know it works because my dad did it for a year on his Ford ranger. when he first bought, It would struggle to go past 70mph. After the treatments he gained mpg and ran smoother. The truck would pick up and not struggle anymore.

Good presentation. I use it all the time on my 2002 Sequoia (387,000 miles).

I'm in the UK, i was introduced to Lucas tune up in a tube, by a mechanic, who worked at RAF Lakenheath, an American airbase, back in the 80s, used it on every vehicle since, never had any problems with my vehicles, none of the rough running that plagues many modern cars, and never had a MOT failure on emissions, equivalent to the America smog test. Based on my experience over a long time, tune up in a tube does exactly what it says on the bottle

Lucas I use also. Extends engine life plus mileage. Works for me.

I prefer the Lucas. I just bought a 2015 Hyundai Elantra and poured a whole bottle into it. Now the car accelerates much smoother and it is no longer loud when it goes uphill. I strongly believe in Lucas now. I am a very skeptical person so Lucas has won me over. My Elantra now runs as smoothly as my Forte. Thanks Lucas!

I have a 2012 bmw x5 with the n55 engine and a custom tune. on average i get about 350 miles on a full tank(20 gallons). With the Lucas complete fuel treatment I get 410 miles on a full tank. I buy the 1 quart size bottle and i get 4 fills out of it. It pays for itself almost 4 times over.

Good coverage. Have used Lucas top cylinder lubricant for decades in many vehicles. I'm more impressed from the lubricity factor for fuel pumps injectors/pumps etc.

I have been using Lucas for 15+ years in my Duramax diesel. I do it to keep the injectors and turbo clean. Jusr the parts to replace injectors can cost up to 4 thousand dollars. I could care less about the milage. I had to replace a turbo before I started using this stuff at a cost of $3500.

I love lucas oil. It cured the little put put put in my F250 4.9 idle. I also unstuck a valve in my mower the other day. I had a valve stick in my emergency generator a year or two back. Intake valve stuck and the engine would spin and pop out the carburetor. I used WD 40 for that one because I didn't have Lucas technology back then. I never put fuel in my truck without it.

What a great video! No crazy hype and circus clown drama, "Just the facts mam". Wish all tutorial videos exhibited this type of common sense. Many Thanks!

Still watching and enjoying the education! Btw- gas is $1.86, before discount, in parts of Virginia.

My 2005 Ford excursion with the 6.8 liter (V10) used to get 11.5 mpg all day long, highway or city, since I've started using Lucas fuel additive I get 16.5 mpg.

I had a whole gallon that I had not used yet. Just purchased a 2018 Buick Enclave 60K miles thinking of adding some to the tank. What a through evaluation of the two products.

My 2006 ford e150 had the check engine light flashing on 6-15-20 on my way to work. I had new plugs and packs put on at 100k miles. This was at 109k so i figured it was injectors and added MMO to my tank and the light turned off. Now at 112k miles the check engine light was flashing again. I put lucus fuel injector cleaner in the tank and it's fine again. I put another in my door pocket for next fill up. I think if I just keep using it it will always be ok

Thanks for sharing all the work you've done. Looks like I'll start using Lucas in my old Land Cruiser.

Great analysis, sir. I just now put some Lucas in my 4.8 silverado. Never used it before. Currently 15mpg city at best, will see how it improves.

I love your content about car related topics and also how you provide information so it's easy to interpret. I am subscribing to your channel. Keep it up.

Back in 2016, my 2002 Chevy truck needed to be towed to my mechanic to have the fuel pump replaced. When I picked the truck up, my mechanic suggested using Marvel Mystery Oil in the gas to keep the new fuel pump lubricated, and it would also clean the fuel system including the fuel injectors. I also added MMO in the gas of my 2002 Lincoln Town Car. Almost right away, I noticed the idle was much smoother in both vehicles, and they seemed to have more power. Another benefit of using MMO was better gas mileage on the highway. On my next 815 mile trip from Maryland to Florida after using MMO, I was now getting an extra 1.5 to 2 miles per gallon in my car. I am now using 2 less gallons of gas on each 815 mile trip. With Walmart selling the quart (32 oz) size of MMO at $3.88, I am using about $1.50 in MMO, but using 2 fewer gallons of gas on each one way trip. With this in mind, I am actually saving money using MMO, plus the added benefits it provides. I was about to buy a gallon of Lucas fuel treatment last November in a very cold state of Maryland, but didn't based on a review that I had read about Lucas gelling up in very cold temperatures and not being able to be poured into the gas tank if it was stored in a very cold trunk. Now that is April and I am still in Florida, on my next Walmart trip, I might buy a gallon of Lucas. I have never had any issues of storing and using MMO in very cold conditions. Thanks again to Chuck who did a video about this very same subject five months ago. Frank PS I filled up my car with gas yesterday in Ormond Beach, Florida, at a Mobil station at $1.89 a gallon. If gas prices keep falling, maybe I can find gas at 29 cents a gallon, the price of gas in Maryland before the oil embargo hit in October 1973.

I consistantly get 1-2 mpg better using Lucas in my 1995 Chevy K1500 4.3.(also in my 2008 Jeep Wrangler Rubicon 3.8)otherwise it tends to get around 14 mpg or less.Tuned up,runs well,(with or without.)thats a big improvement percentage wise. I run it in all my vehicles. I swear by it. Old saying...if aint broke dont fix it....meaning it works for you without harming anything then why stop. And I truly believe it helps keep injectors etc clean. I believe on all my vehicles I've seen improvement but never more than 2 miles per gallon. When you're running vehicles that don't get the best mileage to begin with that's quite an improvement. I have heard contradiction about additives...but I see it's benifits for myself so I dont see how my own results could false.

Thanks for all your had work and time to make this video 🤝👍🏼✌🏼

I smell absolutely nothing from the lucas treatment...I add 5 ounces to a full tank ..I cant see anymore MPG honestly but it did smoothe out the rough idle and throttle response is better ..I run shell 87 octane.. 01 F150 4.6 liter with 110k miles ..

The only additives I add to my fuel are PEA products like Redline SI-1, Chevron Techron & Gumount Multi System Tune-Up. Since I run E85, the fuel economy is pretty crappy anyways, and with all that alcohol content, probably don't even need to run the PEA additives? Nice to see I'm not the only one that reuses bottles :)

even if you spilled a whole gallon of MMO in your trunk, I think it would be fairly easy to clean up. I'm more blown away by the fact that you are getting more than 10mpg better than I am. I have been keeping detailed business records for over 2 decades now and more recently have been keeping MPG records with it. My Panthers, all 3 I've owned, are stuck right around 16.5mpg @ 70% highway miles, which is about the same I get with my 2004 Cobra and my 5.7 Charger and 3.5 better than I get in the Avalanche 5.3L. When I had a 460 V8 Ford F250 I calculated that in gallons per mile

Damn..... One of the best explained video in RU-vid...👍

Enjoy your videos as always. I was expecting you to run with Super Tech TC-W3 Outboard 2-Cycle Engine Oil on this round. You referenced a thread on LS1 by a guy named Sarge, he seems knowledgeable, he had the following to say regarding Lucas on another post: "Use 1oz of TCW3 per 5 gallons of gas. Lucas does not have the cleaning properties as the TCW3 has. TCW3 also has better lubrication properties. Lucas Oil Stabilizer is just viscosity enhancers. Period. Does nothing else. If your sump uses 6 quarts just substitute 1 quart of 20-50 and you gain much more benefits than Lucas Snake Oil." I personally bought TC-W3 after ending my MMO gallon a few days ago but have not had much opportunity to drive around so cannot share any of my personal results. On another note Acetone is also purported to increase MPG and is used in numerous fuel additives like Berryman-B12. I would be interested to see your results using Acetone only and Acetone + Lucas. Internet suggest ratio should be 1 to 3.5 oz per 10 gallon.

Lucas can also fix a sticky fuel gauge (not the actual gauge but actually the cause in the fuel pump that causes the gauge to not read accurate or slowly) It's also a fuel stabilizer (if I remember correctly) so it'll help with all that nasty ethanol in the gas nowadays. I recently used it on my 17 accord, for the 1st time in maybe a year. I quickly noticed that the engine idle noise went down a bit and my fuel lasted longer (almost twice as long) unfortunately I didn't really do any tests, but I had been using MMO like 4 months prior and it didn't have nearly the result. I do use MMO about 1000 to 500miles prior to a oil change though, since it does a decent job of cleaning.

@Panzer Platform: I've been using TC-W3 exclusively for about a year now since I got rid of my Marquis and got my first CVPI - I believe it's cheaper than even MMO by like a dollar (when I bought it I think it was 13 or 14 dollars for a gallon.) I go by the commonly accepted 1oz/5gal, and contrary to what some people say, I fill up first so I know EXACTLY how much I should be putting in, then I put the TC-W3 in - I have a 1oz turkey baster that I use to measure it as I've found those bottles like the Lucas one etc are more inconvenient to use for 2-3oz at a time. We don't pump our own gas here in Jersey so I figure it'd look kinda odd to the attendant to hop out of the car when he's done and grab a turkey baster and a bottle of blue stuff and put some in my gas tank LOL, so I'll drive to somewhere else in the vicinity and put it in, then either continue on my drive or go in the store and kinda let it settle a bit and hopefully mix a bit on its own before it gets mixed from movement. I haven't gotten as in-depth with savings per year and what-not as you have, and I definitely don't hit the same pump in the same station every time or anything like that, but there is a definitive 1-2mpg increase in my mileage when using the TC-W3 vs not using it; regardless of how aggressive I am with my speeds or how much city driving I do. I have done enough tanks with and without it over the year to see the trend. I typically get whatever 87 is cheap around me besides a couple stations that I know add too much ethanol to their stock. Never noticed any increase in mileage from using 87, 89, 91, or 93 - and I've never noticed much of a difference in going to a Shell or Sunoco over other not-as-nationwide name stations. I will say that I must just drive in an inefficient manner (or I'm not on the highway for nearly long enough) because I see people all the time saying they get 19+ in P71s, even with the 3.55 rear. I have 3.27s and my best mpg to date is 17.4mpg. Granted, my alignment is ever-so-slightly off and these tires are 3-4 years old, and I'm assuming it's on original coil-on-plugs (with iridium plugs put in ~20k ago.) Besides that, nearly everything that could effect mpg mechanical-wise is new or relatively new. So I guess it comes down to my feet, which are pretty heavy. I certainly do not drive like a micromiler despite my efforts to at least TRY lol.

I poured at lease 3x the recommended dosage of Lucas into my Chevy Cruze. No issues whatsoever.

G'Day mate Here in Australia Lucas fuel treatment costs $72.50 for one of your gallons or 3.8lts or so.I like it though. Cheers Rory

Also warning. The MMO has sulfur in it which will ruin catalytic converters and DPF on diesels. Lucas has none.

Is Lucas fuel ok safe to use all the time ? And what's the difference of a fuel injection cleaning from the dealer when they hook up a cleaner to the fuel injectors

I’ve been using Lucas for 9 years. in the last 12 months my truck started using gas not sure what’s going on I still use Lucas I’m going to make sure it’s nothing to do with the wires and plugs I keep a clean air filter in it about ever 6000 miles and oil changed ever 3000 miles plugs look good I will get them checked again make sure nothings going on there and of course I get my wires checked again ?

So what exactly is this stuff doing/treating? I know that offsetting the hazards of ethanol contamination, is not really a factor with our flex fuel E85 Panthers, but with older cars that could be a concern. So does this address ethanol issues & water in the gas tank?

What is the best way to add this? Should you pour it in before adding gas (to allow the incoming gas to mix it up) or just pour in after filling up or does it even matter? Thanks!

1 oz of lucas treats 3.125 gallon. 400/128=3.125

Thanks for information going to use Lucas and now I know how much to add per gallon Thanks

$4.00/gallon, LMAO. Those were the days. 😭 Thanks for taking the time and punching the numbers.

Good catch on the red flag🇦🇱 well done thought out & researched.

Really like the old school print outs vs just screen shots

I started using Lucas Oil treatment on my first bottle saw the mpg went up by 1 mpg (from 17.8 to 18.5). But after my second tank fill up I've noticed the mpg went to down or got worse (17.8 down to 16.9). I put 4oz per 10 gallons should lessen the amount of Lucas I put per 10 gallon instead?

I use the lucas for fuel and Marvel in the crankcase on oil changes

Have you tried the Synthetic MMO???

The Gallon here in the UK is £48 or about $60+. So you’re still good. Can’t wait until the UK and US has a trade deal.

i use this product at every time i fill up or add 10 gallons or mor per fill up. i have a 97 Land Cruiser w 335k on the clock original owner and it is my daily driver.

I also purchased a gallon of Lucas. I keep refilling the 5.5 oz Lucas bottles that I previously purchased. I normally run a bottle through about every third fill up. I’m wondering if there is much difference in fuel economy numbers by using it every fill up verses regular intervals, like I do. That might be a good test.

Extra 20 or 100 dollars per year is worth it to protect / improve the car / engine

Great study! At one point, you address the proper ratio of the additive to fuel. I'm perplexed as to why the Lucas 5.25oz bottle treats 25 gallons, but when you purchase it by the quart or gallon, the label assumes 3oz per gallon? Either the small bottle should be 7.5oz, or the larger containers should treat 152 & 609 gallons respectively? My plan was to simply refill the small bottle with the juice from the larger container. Is my plan flawed?

I get the gallon of Lucas from Advance Auto for $23.79, I do it by them price matching rockauto so I don't have to pay the $10 shipping, not many people know this trick.

I need a link to those bottle containers you use to pour the fuel treatment

Just paid 50 for one in Canada

What are your thoughts: I wonder if the amount of savings achieved by using Lucas is not higher? Your #s are perfect, what I mean is that the reason I use Lucas is in lieu of high octane gas, which can be as much as 30% higher at the pump. Therefore the amount saved is $75 odd per year plus the difference in types of gas consumed. The only way to get similar performance without Lucas is high-test, so I save 6% plus the gas cost difference...

Also don’t forget as you fill up fuel there will be treated fuel still in the tank not a problem with the Lucas , but could be with the mmo

Can I the lucas in every tank fillup of gasoline? I use the little bottles and refill them instead of putting the exact amount so I put a bit extra.

Just wondering where did you get your measuring bottles from? That is a great idea to preload the bottles for when you stop by the gas station and they are already loaded to the right measurement for a full tank. I get home and forge to load my Lucas.

Going from 3 ounces to 4 ounces is a 33.3% increase.

saves you $70/yr ? . . that is $1.40/week? . . . is it worth the effort using just to save $1.40/week? I really couldn't be bothered personally

Very good review definitely will use in my fleet !!

I Bought A Quart Of Lucas Fuel Treatment At Walmart For 9.97 Now I See The Gallon Is Only 25.97 I Bought A Gallon Today And Will Take The Quart Back. I Have Used Lucas Fuel Treatment For Years. I Put Lucas Engine Oil Stabilizer Treatment In My Geo Metro And Within 500 Miles The Engine Got A Rod Knock And Wasent Driveable Any More

That's a $44.99 jug here in ontario Canada

This guy got his budget balanced.

My 2014 F 150 sounds like a diesel on 87 octane,so I always ran 89 or higher octane.With Lucas ,I can run 87 again.I always "over treat" by about 3 or 4 ounces.One thing to consider,with a cap less fuel tank,buy the little bottle of Lucas and save it,like the guy in the vid.Otherwise you have a hell of a time getting it into the tank.

Just bought a K&N air filter cause I want to boost my MPG. I used MMO for a bit but maybe I should look into Lucas... Even though we cannot drive anywhere currently... Hard times.

Hi Panzer, do you consistently have mpg improvement when you mix Lucas fuel treatment with gas?

Thanks a lot for your video. I have one question, how frequently should I use the Lucas complete fuel treatment?

its $27.98 now, just bought some today from walmart

Did the bottles Leak if it tipped over in car ?

wow, you did your homework, thank you! 🙂

Its $29 gal now at Wally World. You still using it?

Curious if you undertreat will it still work and by how much? Great content bro 👍 love the science

Have you tried stp? Your thoughts?

big balls here put 16oz in 25 gallons Lucas

Now $29.99.

Does the tank have to be full to use it or no I’m having MPG issues with my 2000 F-150

Why is everyone using 87 and not 93 ? Also, how does Lucas compare to Techron ? Is it better ?

Great review! I noticed that Lucas now has a high mileage fuel treatment product. Do you know what the difference is between the two? My truck has 169k miles so wasn’t sure which I should try.

Have you ever done a long-term test with MMO to see what it's MPG increases were?

Great video. Where did you get those small clear bottles at?

I own a new Tacoma, would you start using this on a new vehicle? How often? Thanks

I bet this dude logs his odometer reading in a notebook on every stop, despite GPS already telling him the EXACT driving distance.

Sorry but important information is missing here Before and after HP Torque Spark Plugs Compression Numbers Injectors

How often to use . At every fill-up?

Great video!

Question: Have you fully tested the Super Tech 2 cycle engine oil or did you decide against it based on potential ill effects to a catalytic convertor?

Used it for years with great results

Where do you get gas (what brand) also what octane?

Well done sir thankyou

You must think about how much will extend the life of your fuel system. This stuff will put much more money on your pocket, than 70usd!!!

in europe you pay 55 dollar thats a ripoff

3oz to 4oz is 33% more

Does the stuff actually do anything?

👍🏼🤜🏼🤛🏼

$ 34.99 in Sept 2022

5 stars! ⭐⭐⭐⭐⭐

Didn't you have another video using Walmart 2 cycle oil @ 2 oz. per 10 gallons of fuel?
