I told him what my major was and he was curious to see how much I knew about engines.
What did you study in school? I am trying to contact the major oil producers to see if their synthetic products are group 3 or 4. I guess that group 4 are the only 100% synthetic oils. From what I saw on pirate4x4 Castrol is class 3 and maybe Mobile 1, Royal Purple and AMSoil are group 4. I will post if I confirm anything.
