Thanks for the update on weight availability, Stuart. I'm among the silent minority who feels the performance of Group III based motor oils is underrated. It's their PRICING that I normally object to. Though I have 48 quarts of Chevron Supreme 10W-30 conventional in the garage, I'm about out the door to canvas several nearby local Pig Lots for some of that 5W-40! Yum! Auuggghhhh, I've fallen off the motor oil purchase "wagon" and can't get back up. (And, I'll valiantly fight off any and all comers who come to my aid!...)
