Well by saying an API SM oil is good, then I guess everyone can get away with GTX2 then? API specs are not hard to meet. ACEA are tougher. <_<
Every half decent oil is API SL/SM rated now. Mobil 1 is SM. So is Castrol GTX2. Does that mean they are as good as each other? Obviously not. So by saying Fuchs meets API SM its suddenly a great oil? No. OE certs are usually harder to meet than API standards such as MB and VW's so they are more relavant. (Although I wouldn't expect GT1 to meet OE specs just like 300V, Redline etc)
Looking at raw details such as the base oil, the additive packages and performance in UOAs is more of an indication of how good an oil is, not just what API spec it is. And Fuchs in this regard have shown nothing out of the ordinary.
Then again any oil isnt even at least API rated SL, it doesn't be deserved to be put into any car whatsoever!
