Oil Change Pumps

[Mikeso51]

Does anyone have experience of using pumps to extract the oil from the sump through the oil filler cap. I see on eBay that there are lots available, both electric and manual, but I wonder how effective they are. In particular the pipe has to be very small in diameter to go down to the sump, so it seems to me that the extraction rate must be very slow.

I know that this is not the most thorough way to do an oil change, and I am not asking for views on this aspect. I am just interested in finding out if there is a pump product out there that works reasonably efficiently with the Audi 1.4tfsi engine.

Thanks

you don't remove the oil through the oil filler cap you remove it through the dipstick tube/pipe... now new cars have an oil level sensor and some lack the dipstick all together but the pipe is still there, it's just capped off. remove the cap from the dipstick tube/pipe and feed the thin oil extractor through it until it can't go any further than you can start extracting the oil.

I have one myself, and have used it on a myrad of cars... but if i have the car up for whatever reason, i just remove the sumpplug. way faster than using the oil extractor, but it's less clean. you still have tto transfer the oil into another container vs using an oil extractor to pump it straight into old oil containers.

Thanks for that. Further internet research suggests that a manual pump is just as fast as an electric pump, so I’ve just ordered one.

yes the differences are neglectable, plus the electric versions requier you to clean the oil from the pump and relubricate it because if you don't need it for a while they can seize up completely ( yeah not what you'd expect but somehow the seals perish inside the pump when that happens) rendering the ellectric oil extractor pump useless. I went manual extractor after that... but i still prefer to just remove the sumpplug especially if i have to remove the oil filter from the bottom, that means the car needs to be jacked up so inthat case using the extractor is just not needed. if the car has one of those top loading paper/cotton filters the oil extractor pump is really handy to suck that part clean tooo

so i'm not against the oil extractor pumps, it depends on the engine and the type of oil filter the car actually has.

Yes. Just used mine again yesterday. They work brilliantly. Quickest, cleanest, easiest oil changes i've ever done. Think mine was £30 from ebay.

I’m convinced!

I cover very low annual mileage in the A3 (I have another car). Last year it was less than 1000 miles. So while I’m happy to change the oil that has been sitting there for 12 months, changing the sump plug, seal and oil filter, plus the hassle of getting the car up and removing the under tray etc every year seemed a bit daft. Which is why a quick oil change using a pump appealed.

They are perfect for that but I wouldn't leave the old oil filter in, why you ask? well if the oil just sits for a year the oil filter can get clogged even though there is no circulation the filter holds about 500cc of oil when the level is at max. slightly less when the oil level is at the middle of the oil level and only empty when the oil level is under Min on the dipstick. In your case i figure it's still at max so the filter is submerged in oil. best to replace it. (they aren't expensive anyway)

I take your point, but I think it may be a counsel of perfection. I covered 190 miles last year, and I find it hard to believe that the filter will be clogged. Cost is not the issue, it’s the hassle of getting the car up and removing the under tray in order to reach the filter, by which time I might just as well drain the oil in the usual way, removing any benefit from a pump.
