High quality oil at a fair price.
I service air cooled engines in the south. I've used this grade of oil for many years with great results.

The Swiss Army knife of engine oils! Highly recommend
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
