If necessary and H-D 360 is not available, add oil certified for diesel engines. Acceptable designations include: CH-4, CI-4 and CJ-4. The preferred viscosities, in descending order are: 20W50, 15W40 and 10W40.
Yes,my manual says the same, thing is, I did post in another thread or two or three that its a challenge to buy 20/50 c rated oil. There are some, as others have pointed out, Amsoil 20/50 diesel oil, Mystic 15/50semi syn (made by Citgo) and someone just pointed Brad Penn.
I think for now Ill stick with the HD360 conventional as you can still buy it locally but can change my mind in the next month or so when ready for a change.
