Penn Grade (Brad Penn) oil
I used Brad Penn for many years as my engine builder recommended it and was a dealer. I had good luck with it. He does a lot of research and found that Brad Penn was sold a few years ago and the new owners changed the name to Penn Grade and were skimping on some of the additives to the point that he no longer sells it or recommends it . He recommended using Driven GP 1 10W30 which is basically the same as Brad Penn with the additives still in , it's even the same color. Just my two cents as I know there are a lot of different opinions on oil... still have the " swag " and a quart left
