I know for a fact after chatting to 2 different mates that work at vw dealership and the other for a ford dealership, most if not all of dealers are now using the above method in order to keep service times down (saves taking the undertrays off) he said he tried it on his car pd130 golf both ways and is sure it gets a little more out with the suction method as you can empty filter housing etc, most people will still argue though that 'not' doing it the traditional way isnt as good, whats everyones thoughts? im not sure but i guess the dealers have considered it fine to do.

its quick, but doubious to get all the sludge that can build up in the sump out, have done it hundreds of times on customers cars, but honestly would not do it on my own.

I've been using my Pela Pump (oil extractor) for the last 6years or more.

In that time my R32 Golf has almost done 100,000 miles, and on my Fabia (bought 2nd hand), I've already clocked an extra 30,000miles.

I do all my own oil changes this way.

My R32 hasn't blown up, nor has my fabia. My R32 doesn't use a drop of oil between changes, and I drive it like I stole it, so there can't be anything wrong with changing the oil like this.

There is no issue using these. They suck out all the oil from the sump (if I undo the drain plug afterwards, nothing drips out).

On the Fabia it litterally means you can change oil + filter AND throw away the old oil back into the empty oil containers in around 10mins flat.

No mess, no stress, no oil on the driveway, no getting a dirty clambering under the car whilst it's raining.

This is why I can change my oil every 10,000 miles without a second thought.

Buy one, you won't regret, and you won't understand why you didn't get one sooner

So long as you give it a good drive beforehand to get the oil all warm and mixed up it should be fine and there won't be any sludge at the bottom to leave there. I got one of these pumps and use it as my preferred method at the moment, mainly due to living in a flat though so don't want to annoy other residents with ramps etc.

I don't mind going under the car and draining frome the sump

Its free, and I like freebies

I took my tray off on a speedbump so its simples to change the old way

My neighbour has a two-post car lift, so it's dead easy to get underneath and drain the oil from the sump (amongst many other things)

That said if I didn't have a ramp handy, but did have one of them extraction units, that's what I'd use. Makes no difference really!

There's always going to be remnants of the old oil in there mixing with the new no matter what you do. You could fill up with new oil, run the engine, then drain that too - but on most of the newer engines you probably couldn't get away with using cheap oil to do that.

I use a Screwfix version of the extraction pump, a bit cheaper than the Pela ones.

Have a drive to warm-up the oil, let it settle, start the extraction process, check all ok and fill up with fresh oil. Job done.

I bought a Pela pump online last week - £35 delivered.

Tried it out on my Rover yesterday and found that I had to give up on the first try. I'd taken the car on a 7 mile spin to warm it up, but this wasn't enough to make the oil really thin, so the Pela couldn't such it out.

I ended up tipping the oil I'd just removed back in (a couple of litres), then going on a longer drive to make sure the oil was really hot. This time it sucked out much easier.

I'm really pleased with it - it makes oil changes much more convenient.

So in summary, if using a Pela pump, make sure your oil is really hot.

I prefer the old fashion way of going under the car, much better and in my view a lot easier

It should go without saying that (whatever oil change method you use) the Engine Oil must be upto 100% operating temperature.

Take the car out for a decent fast drive, use high RPM to get proper heat into the engine.

Diesel engines especially so because they take forever to heat up, and they cool down very very quickly indeed, so bare that in mind too.

Oil changes done at Car dealerships often are done after the car's been sat in the parking lot for the morning, so the engine oil will be stone cold... Another reason why it's better to change the oil yourself...
