Do you recommend using oil extractor/syphon rather than draining from sump plug?

As the Yaris engine oil filter is accessed underneath the car it must be logical to drain the oil from the sump plug?
Change the filter while the oil is draining.
The above is much cheaper too. The Yaris dipstick tube isn't too big diameter wise either.
The o.p. doesn't say what year the Yaris are. Later engines from around 2009 need the correct tool to change the filter element too.

If your undertray is held on by a load of cable ties like mine, crack on.
If you've got the money and want one, get one.
As already mentioned, getting every last drop out is no big deal, as most times the half litre in oil cooler doesn't get drained.
I think best thing you can do is shorten distance between changes.
I look at some of these cars for sale, 20k miles between changes on a turbo that rapes the oil? Kind of off putting for me. 10k is long enough.

Two trolley jacks, old washing up bowl to drain into, doing the job properly takes minutes, the sump is completely empty, whilst the last dregs are dripping a quick change of the oil filter, job done.

Keeping the car for years?, fit a Fumoto oil drain valve in place of the sump plug.

If you're buying an extractor, don't bother with anything other than a Pela. They kick all the others into a cocked hat.


Many people will tell you that extractors are rubbish, that they'll leave loads of sludge behind in the sump, etc etc; but I've been using one for years and have never had problems with dirty oil or sludginess. Don't forget that marine diesels have had their oil changed using vacuum extractors for years - you cant get at the sump if it's in the bilges.


On my dad's motorhome, I've been changing the oil for about six years and 70K+ with a Pela, and when we did an engine change for a later DI motor a few months ago I had cause to remove the sump and fit a new gasket before selling on the older motor. It was clean as a whistle inside.


I can change the oil on my V70 in 15 minutes whilst wearing my suit without getting dirty or spilling oil anywhere. Extractor makes it so easy I change oil every 6-8K on all the vehicles I look after, and regular changes have got to be a good thing.

You have posted almost the same as I would have, I bought mine from a supplier on the Norfolk Broads about 9 years ago

V70 (and my old Skoda Superb 1.9TD, and others I've owned) use a replaceable paper-element type filter which is accessible from above and which is mounted upright so no oil drains out and makes a mess. Just a case of having a bag to hand to put the dirty filter in.


Also means I can remove all the oil from the oil-cooler using a smaller bore vacuum pipe on the extractor.

I use a 2 litre Coca Cola type plastic bottle with the neck cut off for the dirty filter

I am thinking of investing in a oil extractor such as this:

The cost of the extractor will easily pay off in less than a year. I can use it only my Yaris, my girlfriends Yaris and my fathers Golf mk6 1.4 petrol.

Are there any disadvantages of using this oil change method compared to the conventional oil drain from the sump plug?

Maybe im missing something in the 40 years since I swapped out motors but you do not need to SYPHON engine oil - ever!

The drain plug is always at the lowest point of the sump (no accident) and if you leave it out for few minutesafter the initial Drain to drain the residual oil then your sump will be drying than you could possibly Syphon if you did it for 40 years

Thats purely physics!

This is as opposed to gearboxes that have drain plug half way down (again by design) so you CANNOT drain the gear box oil iut fully so you either have to replace a few times to FLUSH OUT oil oil completely or use a syphon such as you posted

But no need on an engine/sump

Thats just physics which hasnt changed in the last 40 years

Every gearbox I've ever changed the oil in has had a drain plug at the bottom. They've had a LEVEL plug half-way up, which is the point you fill to...

I brought a cheap column style sealey one off of flea bay and it works perfectly , from memory it was £50 or £60 inc delivery and I've done engine oil on my camaro and my shogun, also did the trans fluid on my shogun with it so if you want to waste your money on a brand name one feel free.

See if its still working after you've done 50, or 100 changes. My money is on 'buy cheap, buy twice'.

I think we've covered this (I know I have). People will argue whether it's right or wrong to use an extractor. No one said at any point to my knowledge that one 'needs' to extract oil with a vacuum extractor (or syphon, if you prefer); simply that for some, me and many garages included, it's easier, less messy and quicker.


If it's any less effective in terms of removing oil volume (which I've explained in the context of the oil cooler volume several times), then it's marginal if at all.


Physics has nothing to do with it, as 'need' hasn't come into it.

Yep, me too.
