I highly doubt there will be any difference in MPG. That is obtainable in testing conditions and that is what matters for certification. In real life, highly doubt. I personally for example never observed any MPG change going from 0W20 in Toyota to 5W30.

LL-17FE I guess is the mid saps version (C5) which is backwards compatible with LL-14FE. Very difficult to find either of these specs outside of the dealership. Fuchs has an LL-14FE approval which isn't too expensive and LiquiMoly is coming out with LL-17FE shortly.

Anyone really know if running a regular 0w20 A1/B1 in these cars would be a bad idea? Maybe they just don't have the long life requirement?


Some of these engines have a particle filter in the exhaust which will be the deciding factor on what oil you should use.
