Mobil 1 oil weight

[Grant Lenahan]

A few other suggested good quality oils:

Redline, AMSOIL, Purple stuff - all supposedly top shelf. Hard to find. 
Costly. Sometimes not type approved for warranty purposes.

ELF Excellium - very good numbers, PAO based, approved by about 
everyone (MB, VW, Porsche, A3/B3)
(same is true for M1 0W40, BTW)

German Castrol -aka BP developed for ACEA specs

And one I would not ignore, although it is Group III ( I dont give a 
hoot) - Shell Rotella T 5W40 synth
Good oil, good numbers, high levels of detergent and zinc additives.
