With regard to relatively thick ester based oils, why does RedLine have high fe numbers and Motul low, low fe numbers? Is it the scavenger effect?
With regard to groupIII+ oils, why does relatively very thin Sustina and TGMO run so clean, and shear so little? Why does thin MGMO shear with high amounts of moly in the oil.
With regard to deposit control, why does groupIII Castrol with a moderate NOACK score better than Amsoil in the TEOST? Don't we need to be smart about NOACK as well as VI/VII?
With regard to driving a BRZ/FRS is the goal good track times and also passing a smog check?
Wouldn't it seem that a thin GF6 compliant GTL oil would be the answer?
Just asking-in a whispered tone of voice.
