Don't really want to start an oil debate but interested if anyone can clarify (preferably a workshop or oil manufacturer rep ect):
Long life 04 vs long life 01.
It appears that long life 04 is the higher spec however it is not recommended for use outside of europe. Which then makes me question why liquimoly recommends its ll4 approved oil where ll01 and even ll01FE is spec'd (4200 oil in their lineup).
This oil appears to be one of the only oils on the market that has ll01FE spec as well as acea a5,a4,a3,b4,b5 albeit as a recommendation and not as an approval ( guessing it'd have to meet this spec to be advertised as meeting it even without the approval.... Correct me if I'm wrong?)
I'm sure either a ll1 oil or the moly 4200 would be fine at 10k km intervals (which I'm doing) but just curious on the differences. Hopefully someone in the know can clear this up as there seems to be alot of misinformation floating around the internet.
