Servicing and Engine Flush?
Hi all,
So, similarly to the way when changing your coolant you would drain and maybe run de-ionised water to clean/flush it, then top-up with your coolant.
Can the same be done with the engine, I ask? Some say when draining engine oil you sometimes get small particles?
If I wanted to, what could I use to flush before topping up engine oil?
Cheers!

There are machines that do it. We have them at work. You hook it up to the drain plug the machine has a vacuum pump that sucks the oil thru a big special filter refills thru the adapter that threads on to the oil cap. You can find a shop that has one to do it. Not really a way to do it your self without wasting a ton of oil.
If the correct oil is being used you shouldn't need to do this.

I've been reading, mostly spotted old threads at other forums but one of the most commonly suggested if you wanted to flush the Engine oil is to run cheaper oil for a short journey then drain.
I think even then, you'd need to do that a few times. Any idea how come the Engine oil turns Black so quickly? Suppose there's no avoiding it. It's a Diesel btw, C200 CDI.

DiNZI,
IMHO unless your engine has done hundreds of thousands of miles or is sludged you are completely wasting your money & time.
Use the correct MB diesel oil (ESP 5w30 - MB 229.51) & change it regularly is all that it needed for a long service life.
I change my 220CDI oil every 10,000 km or 12 months a little more frequently than the book. Maybe I am wasting my money too!!

My mechanic told me diesel oil is immediately dirtied upon refilling, so you wont even know if the oil is dirty ever. You just need to follow a schedule;
7.5/10k is good. I have one too and any later than 9/10k MILES not km and youll feel it

You never get all the oil out. It in the head/heads, oil galleys, turbo, in the oil pump because it stays primed. You want it there so you don't have dry starts. When I rebuild an engine from being spotless clean it'll take .8 to 1.2qts over what a normal oil change is. Because of that remaining oil it'll turn the new oil black. Diesels are full of soot. That's what turn the oil black. Synthetics suspend contamination so it will turn black quick.
If you ever drain out clean Oil use better oil. Oil turns black because it's doing it's job. It has detergents to clean the engine.
