Oil change pump @ Lidl

Disregarding crossflows, A series pushrods with combined engine/gearbox sumps and every other old skip made more than 15/20 years ago then does anyone have any evidence of 'bits' in the oil during a change?

I haven't.

Surely if you drop the oil on a 3 yr old 5 series you can't really expect to find stuff floating around the sump can you?

Bits in the oil during a change on a modern, maintained motor = imminent engine failure IMHO.

At every service I perform, I drop the oil into a clean pan and then pour it into the drainer so I can sift through the debris at the bottom. This procedure was introduced after I had a car back immediately after a service for a clutch change - in order to save the client some money I kept the oil (it needed to be drained to remove the gearbox). As I was pouring it into some containers I noticed that the pan was full of metal flakes. These turned out to be fragments from #1 big end bearing. This fluke saved the owner big £££.

From that point forward all engine oil gets drained into a clean pan and sifted. A sample is also sent away to a tribology lab for testing. I saved another engine last month when metal fragments were found in the bottom of the pan - these turned out to be parts of the oil pump chain tensioner. A very cheap fix compared to what could have happened.

If you're looking for evidence then I have photos that I can post.

Very slow. It can be useful if you can’t get beneath, though.

Did you get the oil hot before draining? It takes forever if it's cold.

[MJ85]

Yes, very warm!

My under-tray needs its bolts grinding off, so it will do for now.

That’s a good reason to use one, where it’s difficult or impossible to get at the sump plug. Beyond that forget it!

Who do you use for this?

I bought one a while ago... used it a few times now, recently to remove some oil out of the auto gearbox on my jeep... i changed the oil and filter a few months ago, but of course there is a lot left in the torque converter so you cant change it all... so to be sure ran it for a few days and sucked as much as i could out(3ltr) and topped it back up with new.

Used it on a boat engine as well, made that job easy.

I still drop the plug where its practical though....

I do oil services in between the dealer services on cars I own, use these

I also assume the dealer uses them, but in my view changing the oil twice as often is much better than changing it half as often via the sump plug

Got one in the end, made a nice neat job

I had one of the battery pumps, I found them slow and noisy. Bought an 8L pela pump instead and have been using that for years. I decant the contents of that into a 25L petrol jerrycan and then when its full I take it to the oil section of the local tip. When I was younger my dad used to make me throw it behind the shed for damp protection!
