Motor Oil
Seems we know about everyone's beard and how tall we are. I'd like some opinions from graybeards on choice of oil. I've always used Valvoline in all vehicles. On the diesel bucket truck I noticed when we used a regular 15w-40 brand it would drink the stuff. When I switched to Rotella 15w-40 (made for diesels) the consumption was nada. No one can cite the reason. On regular brands (Valvoline, Pennzoil, etc) some folks say it all comes out of the same barrel; they just stick their brand on it.
Opinions, and what do you prefer?
