Engine Flush?
Friend just purchased 01 430CLK. The previous owner stated he put regular oil 10w30 Castrol.
Will an oil flush help him transition to syn-0w-40 Mobil-1.
Of course the dealer says ... no ... but I want to here from you ... if you have ... with positive results ... which treatment product did you use or did you go to a mechanic and hook it up to an engine flush machine.
Thanks.

From my experience it is ok to go from reg to syn jut not the other way around. I would imagine the damage is already done since these cars already come w/ syn to begin with. I would flush.

Mixing oils absolutely will not harm your engine...
You can mix synthetic oil with conventonal oil all day long, and absolutely nothing will happen. The one and only disadvantage is that the synthetic benefits will be reduced due to it being diluted by the regular oil...
