Plus my oil temp was almost two needle widths lower(cooler). So I was sold.
I am sticking with German Castrol. 
Btw... I also change my oil every 5K kms. |
But, like you said, in the US, German Castrol may not be the best choice due to the LL04 rating and the high sulfur in fuels here so I'm just trying to figure out what to go with over here.
