Funny, enough I didn't see a topic like this come up in the forum search. Maybe that discussion took place years ago? Or maybe it's too dependent on whatever is sold locally?
Anyway, I've just been using plain Castrol GTX 20W50 Motorbike oil. I don't put on heavy miles or a heavy load and change it every year come winter storage time, so that's been more than adequate for me.
Apparently the local stores are getting some Shell Rotella T6 in on sale. Worth picking up? Bad idea? (My understand was that diesel oil was recommended)
EDIT: Hmmm, looks like the Rotella doesn't come in 20W50 anyway. Still interested in hearing what oil folks are running.
