Curious question.
What kind(not brand)of Oil are you guys using in your shovelheads and why?
I always from the 70's till the 90's ran straight weight aircraft oil in my shovels between 50 and 70 weight.
The guy who rebuilt my motor who has a good reputation and has been wrenching bikes at Harley dealers and his own shop now for 30+years and a avid drag racer said I should run the newer multi-viscocity stuff like 20w50, like the dealer sells for new bikes.
What about for my ratchet top trans also?
I am no oil scientist so, What do ya all think?
