My first post here, although I have stolen more good ideas than I can count. Maybe a sign of spring, or this could just be our local Walmart, but just wanted to give a heads up that Rotella Synthetic 5w40 was on sale at Walmart today for $12.48 a gallon. I'm all stocked up for next winter, but it might be worth a check at your local Sam's. Thanks for all the good ideas, insights, and help/
