I've heard that some folks will add little new oil, after pumping, and then pump that out after letting it "flush" some more of the old oil down. Just to try and get more old out. As someone else said, even the drain plug method isn't going to get everything.
you should put the can and the pump on the ground to take advantage of gravity, like you would with a siphon. Your pump was having to try push that oil directly upwards. Still, even in ideal operating conditions, the drain will of course get a bit more out. You can use clean oil to dilute anything leftover and get more out with this.
I've just tried the exact same pump and I was impressed tbh. As someone else said, put rhe canister on the floor and let the used oil drain into that as gravity will also help the process. For a quick, and very clean way to do an oil change for a DIY-er it's a winner for me.
I use both methods. I like how clean the process is with oil pump. At the end I crack the bolt and take out the rest which is very small amount. Less mess is good day for me.
Thank you for sharing. I do like how you got/found this small pump. Way more compact and easy to use than a lot of extractors I've seen out there. There was another YT channel that discussed this. (Maybe The Car Care Nut? Not sure) While yes he also had a slight difference between suction vs drain, but the difference was smaller than in your effort here. Maybe the lead-tube is different? I don't know. Regardless, one is never going to be able to drain "all the oil". There will be residual oil left in the head (valve train area) that just won't drain down. Oil is also viscous enough that there will always be some the remain stuck on vertical walls and not fully flow down to the drain hole. As long as folks are regularly changing oil & filter, that's probably the bigger impact for longevity of their car/engine. For folks that want to adopt this kind of extraction method, my suggestion is to place the old oil bottle lower - directly on the ground. This way, once the oil has filled the entire suction line, they'll get some "help" from siphoning effect, and the pump is no longer having to fight gravity.
I just bought a vacuum pump for oil change. As a DYI guy I think use a vacuum pump to suck out all the oil and drain out the remaining tiny bit oil just like this video. That is just my way of doing thing. If I do it myself, I already saving some money ,so doing some extra work no gonna waste the time or effort. Thanks for this video
This works well on the renault 1.5 diesel motor (this engine is in loads of different models including nissan & mercedes. Just be careful when pushing the pipe down the dipstick tube that you don't curle the pipe back on it's self when it reaches sump bottom, just feed it down gently and it will get every drop of old oil out
The dealer recommends an oil change once a year , so I use the extraction method myself as an extra change after six months and have it changed by the dealer once a year in accordance with the warranty. You get most of it out without risking stripping the thread on the pan.
I use an extractor and never have to spill a single drop of oil on the driveway or deal with bad oil pan threads on older vehicles. Once a year I'll pull and replace 5 liters of automatic transmission fluid on my GM truck. Also its an awesome tool for changing out power steering fluid, or working on lawnmowers, boat engines, snowblowers etc.
I think the amount that remains depends on your vehicle. Some are designed to have it extracted this way and the design of the oil pan reflects that. I changed my oil last weekend using an extractor and as it was the first time i used that method i pulled the plug too. There was literally two tiny drops that came out of the oil pan. I wont be going underneath my car to do the oil again but i would recommend the first time you do this that you check for your specific vehicle.
Yup old school method works the best. Plus a old mechanic showed me that when your oil is almost finished draining pour in some new oil to get rid of any old oil in stuck in the oil pan. I'm always amazed to see how much dirty oil is still stuck in there
Nope you're wrong. He is using a very weak oil extractor. A good oil extractor will suck the life juice out of your car. You can see videos of those shops using pneumatic oil extractor. Nothing is left when you unplug drain. I will make a video too we have the machine in our shop.
@@aydinali5381 What do you mean? My bike has two drain plugs so I don't think I can use on these extractors. The darn drain plugs are so easy to strip as well but I think I have to use old school method.
I tried to do this and my tube has got stuck inside the oil dipstick tube, it got sucked in a little while the motor was running. Im afraid to turn the motor back on, what can or should i do??
OMG.... I can change my oil in a parking lot and avoid going to a dealer or mechanic that ignores my instruction to warm up the car first and all the small things like stripping the drain bolt? pays for itself in two oil changes!? SOLD.
Я таким же насосом масло меняю. Только перед тем как закончить, я наливаю в мотор новое масло ( примерно 150-200 мл) и опять высасываю его насосом. Тем самым по максимуму убираю старое масло из поддона двигателя, и из самого насоса, которым откачиваю.
Even if you drain the oil from the drain plug you still leave up to half a liter of oil inside the motor. The oil inside all those passages doesn’t drain out completely. That’s a fact of life. The amount of old oil that stays in the engine is too small to make a difference.
On many cars you still need to lift the car or roll onto ramps to be able to remove/replace the oil filter. So I don't see the appeal of this for engine oil. Now for the transmission, this would work well
the electric extractors arn't so good, and extractors access isn't always perfect for each car, some you can reach the bottom of the sump, some you can't (so it's no good). for example honda K20 - no, but mazda b6 or toyota 7afe - yes. the PELA pump is far better than the cheap electric pumps.
That piece of crap pump did not work in my van .it made a big mess instead.i will leave leazyness aside and stick to the old proper way of draining oil.
@@AliMECH You may have to move the tube a bit. If pushed down properly it goes EXACTLY where thedip stick goes which is usually the lowest point. I just did a 2013 Camry and a 2008 Mercedes S class with the Mightvac. Both extracted all the oil. The oil in Camry was clear and clean when checked with ZERO evidence of old oil mixing, took it for a 700 mile drive and is still clear as if I just did the oil change.. The Mercedes was the same. I didnt take it 700 miles but after 90 miles oil still looked new and in no way dark or discolored. The user just needs to know how to do it.
