I've been expressing my opinion on oil weights for years, and I'm getting ignored, ridiculed, and accused of being an ignorant liar. It's somebody else's turn on the bullseye. I use Traveler brand 15W-40 that I buy from Tractor Supply Co. in 5-gallon pails in every 4-atroke engine on the place- - - -tractors, cars, trucks, lawn mowers, generators, a Harley Soft Tail, and a pressure washer. No oil-related failures in the 30-something years I've been doing that!
