I've seen some brief discussion on this, however, no one really gave a definitive answer. Anyone use this stuff? Their 5w20/30's come in a 2 gallon jug for $19.99. That puts it into SuperTech blue bottle territory. Reason I'm interested in it is due to the fact that my truck takes 7qts of oil, and this 2 gallon jug would be about ideal. I looked on the bottom and the 5w30 has the Warren WPP on it, but the 5w20 has a leaf looking logo on it? Input please
