What Brand of Oil is in your BRZ/FRS?
I read through these forums extensively today and I tried to list the Oil Brands in terms of popularity on these forums. I saw more people saying Amsoil than anything. I just want to know the BRAND and if you have time to type, why? Is there really a difference between Brands and what is it that makes one Brand worth $8-10/qt and another $4/qt.
