Hello all, so my Dad just got a mint '05 Heritage Soft Tail Harley. Bought it off a guy who kept it really nice and spot free. He has been using Amsoil in his screaming eagle engine but I would like to use an 'easier-to-find' oil.
I have not checked any motorcycle shops around here locally but I was looking through the owners manual and it says it can use diesel oils that have the rating of CF-4, CG-4, CH-4 and CI-4 so any modern Delo/Rotella/Delvac. It says I can use 10w40, 20w50 but this was for the original engine.
I would looooove to just be able to go to walmart and pick up whatever brand of diesel oil is on the shelves there but since this engine is bored etc from reading I don't know if choosing a 15w40 is the smartest option especially that sometimes it can get in the 90s here in southern PA. We definitely don't want this to get too hot.
Should I just stick with 20w50 to be safe? I might see if I can call screaming eagle or whoever about it.
Thanks all!
