Recently, while reading the back of a bottle of Havoline Synthetic 5w30 API SL, I noticed the following statement: "formulated using 100% synthetic base stocks".
The common theme here is that this is a Group III oil. Can this oil really be all Group III "synthetic", & still make the above claim? My gut says yes. What say the BITOGers?
