For some reason the dealer where my '00 E55 was serviced last put Syntec motor oil in- I just changed the oil myself and went with M1 0W 40. I swear the car has more power, and idles more smoothly. Maybe I'm imagining things, but I have always used M1- and I thought I would share.

What bloody dealer is this?

As far as I am concerned, MBUSA has always told its dealer to use nothing but Mobil 1.

ummm.. if im wrong someone correct me
but isnt there a little sticker at the front of the engine bay saying

"Mercedes Benz and ///AMG recommends Mobil[1]"

or something along the lines of that?

then why would you dealer put anythin else in

I'm a believer in Mobil 1, as is Mercedes...
Seems strange a MB dealer would use anything else

BMW is using castrol. couldn't be to bad

i donno my dealer used to put in quaker state syntec, its cheaper and no mbusa doenst regulate the dealers close enough to monitor each and every oil change.

Using 0-W40 Mobil 1 will allow more power to the rear wheels because it is easier for the oil pump (less HP required to run the oil pump) to pump the oil thru the Motor. This is because the oil has less viscosity and is a superior lubricating film. - Bob

Benzes MUST use Mobil 1.

Hehe. Sometimes cars run better after a service... IF THEY NEEDED IT SO BAD!! How often do you change your oil and how harsh are you on it? Maybe you should just change it more often. It's not a good sign when you see a difference (especially smoother idle) after an oil change. It is a tell tale sign that the oil had broken down.

I drive it pretty hard, I will be changing the oil every 3k miles. Dealer was in Tacoma, WA.

On other cars, I have noticed a dramatic change from changing out a dino oil with 20 easy miles to a synthetic, and a noticeable change from Mobil 1 to Redline.
