How do I identify Group III oils?
I am currently using Mobil Clean 7500 and understand that is about 2/3 to 3/4 Group III oil with about 1/5 to 1/4 PAO.
I want to use Group III oil, and I think Castrol Syntec is Group III but that is the same price as Mobil 1 SS, and Valvoline synthetic is about the same price.
Is there any group III oil that costs less than Castrol Syntec or Valvoline sythetic?
