Oil Q's

Hello all!
Does anyone know if Phillips 66 TropArctic synthetic blend oil is worth using. I have always been a valvolne user, but noticed Troparctic blend was reasonably priced. If anyone has anything good/bad about this oil please post it.
Thank you!

Well the name gives it away. A "BLEND" meaning it's not true synthectic like Mobil 1. It is a blend of hydrocarbon oil stock, it could be group 1, 2, or 3 base stock. Then poly oil base stocks are blended. The problem is you don't know the percentage, which can be 80/20 50/50...etc. 100% synthetic is true polyaphaofins.Amsoil and Mobil 1 are the most reconnized true synthetics using POA's (not ester oils, mineral oils,hydrocarbon based syn.) They is no set standard by the API which states how much POA's must be blended to make them claim it's synthectic. It can be 10% POA to 90% group 2 or 3 (the higher # the better grade crude stocks).
