I still would like to see some lab results, because the Germans that designed M119's were pretty smart and if they could have went with a 0w-20 they would have, it would have improved fuel mileage.

A few usuers of 0w-40 on older engines reported higher wear metals in their oil. I'm not saying 15w-50 is the right choice either but maybe something in the middle.

btw 2.5 bar is at idle? Thats real high btw. It should always peg when you hit the gas.
