On my 2005 230k? That's how I've done it on all of my other vehicles but this is a Merc .

I've also used it on my previous cars like Camrys and Accords. No way in holy hell would I do it on the C230K.

Mercedes engines don't need it. IMHO don't bother. If you really want to put strange not approved fluids into your car it should be fine.

Thanks for the input. My car is about to hit 100k and I've never used this stuff on a car without some improvement. Is there a reason this MB engine would be different? I've seen mild improvements on hard driven v8s and massive improvements on daily driven i4s so I wanted to give it a try to see if I could eek out better mileage.
