Oil is such a controversial subject these days that I don't know what to even think anymore. I'll stand in the back of the auto parts store for almost an hour reading their bottles trying to make a decision. I tell 'ya, one of my motorcycles has a strict rule in the owner's manual to NOT use any oil that says "energy conserving" in the round approval circle on the back of all oil bottles. Street car oil has really gone down the tubes thanks to the EPA stepped in to tell them how to make oil and what they can and can't use as additives these days.
