    I get that not much may drain out, but wondered if ‘heavy bits’ would remain in bottom not necessarily picked up by pump? :) just one of those idle ‘what if’ - I realise the only 100% way would be drain then drop sump pan to really look!

    A magnet would catch them...even if attached on the outside of the sump.

    Me being "old school" i do not like ALL modern methods they are designed to trick or earn others money!

    It has all been done before so i still prefer to take the sump nut out and let the oil woosh out with the force of 8 litres behind it and any sludge or crap that may come with it. The suction method by MB is too slow to do any good?

    This was also an article i read about a problem OM642 engine that had problems with engine bearings etc. and it was due to heavy sludge in the sump due to over use of the oil or infrequent changes?.........so is crap left in there???

    My main dealer said they often Remove the drain plug, depends on the engine sump shape. And where the suction tube ends.
    On the parts list used on a service for the 5.5L engine is a sump plug ... a few quid. And irrelevant to me, as I always get a pre agreed discount price on any service. Kinda price matched.

    But tbh doing under 3000 miles per year. The oil still looks like golden syrup just before the service.
    You can just about see the colour difference on the lower 5mm of the dipstick afterwards.

    Interested in the order of work.
    Sounds like you put in the new oil before changing the filter.
    Any reason why you don't you drain out the dirty oil, then remove the old filer , replace with a new one and then put in the clean oil?

    Yep. You can fill through the filter housing as demonstrated by Cole today when he did the A service on our r230 (amongst other work).
    I found out today it primes the oil pump that way too.

    It might be reading this with a headache but you remove the old oil, pour in the new oil, then remove the old filter. But then I don't get the comment about filling through the filter housing if it's still in place as you've not removed the old filter. Did I mention my head is hurting?

    I wouldn't expect to be seeing machining debris or metal particles coming out of modern engines.Thats why the first service is at 12 months or 10000 miles. The days of running gently to bed in the engine are long gone. In the old handbooks it would say avoid hard acceleration and keep below 50mph for the first 500miles and then change the oil. It did indeed come out with metal particles in it.

    Something found out yesterday. Before refilling remove filter, then refill half through oil filler cap then half through filter housing then refit filter

    You should remove the filter before completing the draining/ sucking out of the old oil, as some will remain in there, held by vacuum until the lid is loosened. We always bath the new paper elements with new oil before fitting as this reduces the time for the filter to be primed on start up.

    Did exactly that on a friends car at mates garage, got as much out as poss by sucking oil out via dipstick tube and oil filter housing, when we dropped the sump plug out there was still a good half pint or so came out, this in my eyes is doing a shoddy job just sucking the oil out from the top, the sump plug needs to come out to do it properly

    Conversely, I removed the sump pan from my Smart after I'd sucked the oil out with a Pela and there was was next to nothing left in there ..... Smart Roadsters don't have a sump plug.

    But I suppose there would have been a few mins delay after using the pump - enough to allow more draining from the engine innards. I've managed to suck up more oil after initially sucking it dry, just by waiting a while. Ultimately I suppose it depends upon the shape of the sump and whether the suction pipe can really get to the bottom.
