Oil suction pump - recommendation
Discussion
I'm looking to buy a 9 litre vacuum pump for oil changes.
These seem to vary massively in price - anything from £29.99 to £145 for what look to be very similar if not identical items
Can anyone recommend a 'decent' one, just for home use. I expect the £30 jobbie will be garbage though doubtless even the £145 version will still be made in China.
Happy to pay up to £75

I was going to recommend a Pela 6000 6l vacuum pump, since I've had mine best part of 20 years and it's been excellent, but then I re-read your requirement for a 9l one, and while they do do something suitable, a Pela Pro 14, only Machine Mart seem to keep them even close to the upper limit of your budget - everyone else seems to want double that, and they appear out of stock.
It's quite possible that the copies are identical to the Pela products coming from the same Chinese factory, or not.
That's some sump you're emptying at 9l ...

thanks for that, I’ll take a look. Audi v6 diesel, around 8 litres.It's quite possible that the copies are identical to the Pela products coming from the same Chinese factory, or not.

I use a pela 6L on an audi 3.2 v6 which is just over 6 litres - the process is simple and quick.
Push thinnest tube into the oil extraction hole until it stops then give it a bit more of a shove because the first stop is an angle of the edge of the sump (failure to do this will only allow about 4 litres to be sucked out of the sump).
Pump up the pela and allow it to become 2/3 full, hit the pressure relief which stops the flow of sump oil.
Leaving the suction tube in place, remove disconnect the tube at the pump end and turn it so it doesn't drip all over your shoes/garage floor
Empty the pela pump into a suitably labelled "DIRTY OIL" container.
Reconnect tube to pela pump, pump it up and drain remainder of sump.
Total time including filter swap ( dont forget to stick the tube into the oil filter housing and get the dirty oil sucked out of there too) - 45 minutes including running engine around the block, finding pela pump and dirty oil can and packing it all away afterwards.
I dump through the sump every second oil change - tested the theory that there would be loads left after the pela pump but actually barely got a drip out the sump after the pela had done its thing.
For some marine engines its the ONLY way to get the oil out - so I am told.

Cheers for the comments - 6 litres is too small and 14 litres is way too big. I like the idea of pulling it all out in one go then I just take the unit to my local council tip and empty into their waste oil tank. I'll probably just take a punt on a cheap 9 litre unit and see how it goes - I only need it twice a year.
I got into these (borrowed one) when I found my sump plug had been overtightened - ridiculous that an M18 sump plug is driven by an M6 hex socket which wants to round off before breaking torque.

I have a 14 litre Pela and it's done me well. Never tried a smaller one so it's not a comparison however it's sturdy, stands well on the ground, and you don't actually need to pump it much. Just set up a vacuum and you can leave it until it starts gurgling.
One benefit that I don't see mentioned anywhere is you don't have to decant the used oil into containers for the tip, just take the extractor and pour straight into the oil dump. Another benefit is that for smaller cars you can comfortably get two sumpfuls in, if you want to change oil on two cars.
On the "that's a big sump" matter, my old Lexus is only a 4.6 litre petrol but takes about 9 litres of oil. IIRC it's 10 litres from "dry" and it retains about a litre. I know there's cars that need more but all the ones I've seen are significantly greater swept volume and/or 12 cylinder engines.

Buy a 6l and empty it into two old oil cans then get the rest out, I hate to think how much extra a 14l one would be. Mine is https://www.amazon.co.uk/gp/product/B000RA16CO/ref... and has no bung so I wouldn't want to transport it to the tip, I'd definitely end up with oil everywhere. I bought that in 2013 and it is still going very strongly.
Also if you're worried about it not being as good as draining through the sump, chuck a can of engine flush in and get the engine warm; I think I got everything including the engine builder's DNA out through the dipstick pipe last time I did mine this way.

Agreed, I have one and it’s surprisingly good.Gassing Station | Home Mechanics | Top of Page | What's New | My Stuff
