Bottom line, they're just a little splash lube engine not unlike any other small engine.
Not alot of experience with them save for the 4000 in our new camper, of which the dipstick is useless. Fill it up like an old Briggs & Stratton.
Oil type, been using dino 15W40 or 5W40 in virtually every 4 stroke engine in the stable for many years. Buy it by the case on sale. Mowers, generators, old Jeep, small block and big block chevys, diesels, Chrysler Hemis (6.1 and 6.4) and the bikes. Bikes get T6 syn as it's wet clutch rated.
Only vehicle I don't use 15W40 in is the boy's 4.6 Triton Mustang. Maybe old wives tale, but told oil galleys are small many years ago when these engines were current and that they don't like anything but lightweight oil. So it gets 0W20.
Occasionally I'll use syn 5W40 or 15W40 in the other stuff if I have it laying around and don't want to go to the store, or it's on super sale or I think, know I'm going to extend the OCI past recommended.
The point is, it's largely not about the type of oil, it's about proper maint intervals.
