I think this is where Mobil corporate is to blame. Mercedes as well many of the other European manufactures have an oil approved list or oils that have met the certified criteria. The problem...

I haven't checked but I am almost certain they call for A3 rated oil that meets Mercedes spec which the 0w-40 euro provides for that extended interval. Using regular Mobil 1 5W-30 would be a...

Amsoil is good oil especially at a time when off the shelf oils were lacking. When those pesky European standards came into the fold the market met the demand and great oil could be bought off the...

That is an outstanding report and it's no surprise. From some of the Mobil 1 UOA at 10k this oil does better as far as wear. The TBN shows that this oil can go the distance.

In regard to oil...

I don't know if the pressure of the fuel is enough during the intake stroke to get passed the rings considering the compression of the motor is much higher. I can see fuel dilution only occurring if...

This does not apply to us because we have both DI and port. If a DI engine is prone for more fuel dilution then it is the fault of the manufacture not the technology. If DI fuel dilution was an...

I looked over the VVT mechanics last night to see where the problem could be occurring.
It's speculation on my part but I believe it could be a problem with deposits on the VVT locking pin.
