yep, at least in these parts. The local "Freds" had a sale on 40W SA - I bought all they had so that now I am the happy owner of 58 quarts, (they made me an offer I couldn't refuse).
Interesting enough, our local "Sam's" has an oil called "Xccel" (I think I spelled it right). Nine bucks a case. It's a multi-weight (multi-grade) 10W30 or 10W40 API SA - I've never see the like
