I switched from Mobil-1 0w40 European Blend(US oil, bought on base at the PX here in Germany ~$8 per liter) LL1 oil and I switched to Castrol RS Edge 0w40 LL4 oil(German made, bought in a German store for ~$10 USd per liter).

I noticed on cold start, that my 135i's engine was far quieter with the Castrol then with the Mobil-1. Same oil viscosity. The engine has less of a metallic clicking noise on cold start in my garage.

I also noticed the oil temp gauge would read 1.5 to 2 needle widths colder with the Castrol.

That is why I switched to using German Castrol oil.


When I push the car on the Autobahn(over ~265 to 285 kph) or when I drive thru the Alps like going up Stelvio Pass or Sella Pass... my MAX oil temps are just above 260'F(just to the right of the middle)on my oil temp gauge.
