I want to switch to synthetic a few guys say they run the t6 Rotella but I can I only find that in 5w40 I'm thinking that I should stay with 15w40..I kno it needs to be suitable for wet clutch application any suggestions?

there's no reason to stick with 15w-40 especially if you are ever in a cold climate

I'm in MN and that's what I  use t6 15-40 excellent oil

I think he means t6 5w-40.  Most people don't understand oil viscosity measurements. Its a little complicated. Most engine wear occurs on start up because the oil is too thick to flow fast enough to cover all the parts needed to reduce wear. a 15w-40 and 5w-40 are the same viscosity at 212'f, the only difference is that the 5w does not thicken as much as the 15w will when it cools. this means your oil will flow quicker on a cold start with the 5w reducing engine wear. You could also use a 0W but the T6 is good, and cheap for a full synthetic that is good with wet clutchs.

Thanx guys I was thinking that the t6 5w-40 would be ok but just wanted to verify for sure..

Shell runs promos in the spring on t6. Get it at Wal-Mart when they have there deal, make out like a bandit. Almost the same price as conventional oil.

Valvoline makes a good full synthetic wet clutch 10w40.
