In an attempt to clear up some confusion about oils here is a break down of the different Groups of oils:
Group 1: Petroleum based oil no longer used (old technology)
Group 2: Petroleum based oil sold as Petroleum motor oil.
Group 3: Petroleum based oil. Refined at a higher temp and injected with Nitrogen. Sold as synthetic based oil by Castrol,Mobil 1, Valvoline etc,.
Group 4: Synthetic based POA oil. Used by Amsoil (they actually use a blend of mostly Group 4 with some Group 5 oil).
Group 5: Synthetic based Ester oil. Used by Motul & Redline .
Group 6: Synthetic based Liquid Gas oil. Not in commercial use as of yet.
