I service air cooled engines in the south. I've used this grade of oil for many years with great results.

Great heavy weight oil for my drift car at an unbeatable price! My engine didn’t blow up so yay

Only oil I use in my diesel and classic cars. Been using for years and love the fact I can now get it delivered- just be aware if using in a car with a flat tappet cam you need to add a zinc additive. Uncle Sam and the epa took those vitamins out so be sure to add back when applicable

Was delivered quickly and at a great price. The bottles had great handles to make oil insertion easy and clean!

Worked fine
