I was wondering if anyone has tried the conventional Rotella T 15w40 in their Africa Twin. I used to run it in my KLR with no issues but the KLR motor was prehistoric compared to the AT motor. There are tons of opinions about how great this oil is for motorcycle motors and I like it because it's cheap and available everywhere. Although I am kinda concerned about using 15w instead of 10w because I ride year round. Any advice or thoughts would be appreciated.
