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

Very true. To be fair, sludge is less common on new cars anyway. Detergents and all that pretty much stop it.

Use a decent quality synthetic oil and you'll never get sludge anyway.

Seconded. As I explained in DM101's original 'syphon' thread, I've been using an extractor for years now and I've never had sludging issues. I've even removed sumps after extraction and seen no evidence of crap being left behind.


In my experience, I can remove more oil using the extractor than a drain plug as I can vacuum oil coolers and the like.

People saying a syphon doesn't get it all out - if you do it properly you'll get more out, as you can suck the half litre left in oil cooler.
As for sludge, please, this isn't the 80's and 20w50 mineral oil.

If you disconnect the cooler pipes, yes, you can. But who does? Especially amongst those who might buy a syphon to save having to grovel on the floor and use the drain plug...

It might not be the '80s, but there's still a lot of people using the cheapest possible oil and leaving it in there until it's utterly knackered - and that's before we factor in those (yes, modern) engines with well-known sludging problems.

If you don't change your oil I doubt you'd buy a syphon to change it...
I can suck it out my cooler, so can DM - assuming this is the tdi, but I lose track of which fantasy car we're talking about

True. And the fact I can change the oil in 10 minutes without getting dirty means I change it much more often.

As I get older I get less keen to crawl about, but on an old average car, if you don't have to remove an undertray it's painless enough just slide a tray under without jacking it up.
Hitting the floods at 80 ripped half my undertray off so it's easier than ever now...


A few ml's left in the sump is far less worrying than these modern tdi's with 20k mile intervals.
Seeing cars advertised with 100k miles, fsh, and 5 stamps in book
I'd do one in between - not only that, but a lot now are 0w30 or 5w30, so what rating is that after 20k - a 40 has more room for loss of viscosity over such miles.

Wow, BeenThroughItAll that is fast. I can do it in about half an hour now. Take it for a spin (thin up the oil obviously), car in the air, drain into a pan, have a cup of tea while it drains, back under, undertray off, filter off, filter on, undertray back on, fill up, yep, about half an hour.

Still, better than paying £45

I think the one being sold by Screw Fix is the Pela extractor?

I have read up online a lot of people do say it doesn't catch the sludge left at the bottom of the sump pan. I'm not too sure, but I wouldn't think modern cars would have sludge is the oil is changed regularly?

If I so purchase this oil extractor, I also would like to use it on my older brothers 2007 Audi A3 2.0 TDI with 185k miles on the clock. That car has had oil changes every 20k miles (long life oil) but am I wrong in saying that even a high mileage modern oil burner wouldn't have sludge?

sludge? In this day and age? Stop using mineral oil

Top up the engine oil with a litre of ATF and leave it in for 100 miles, then change the oil; gets rid of all the sludge as the ATF has a lot of detergents in it.

What is ATF? If any sludge is dislodged won't be cause more damage by blocking up turbo vains etc.?
