I know some here have heard about the lawsuit that Mobil had against Castrol, or vise versa, over the definition of a synthetic motor oil and what exactly constituted a synthetic motor oil. The case came out in favor of Castrol, ruling that Castrol could call their "extra refined crude oil' synthetic motor oil. This changed the definition of what could be called a synthetic motor oil.

Shortly afterwards, Mobil 1 came out with a new formula that replaced the Tri-Synthetic formula now called Super-Syn. The oil is now a bit cheaper than before and is is darker and only says "Fully Synthetic" not 100% Synthetic Motor oil on their packaging. It still has the same odor though. Does anyone here beleve that Mobil 1 took a short cut by adding some refined crude to their oil?
