Good ol Shell Rotella T. Can but a gallon of it at Autozone for what one quart of "motorcycle" oil costs. I have been using it for years. Actually this is the oil Rekluse recommends for their clutches
Atf dexron vi is the best spec oil you can possibly get. GM (makers of the dexron specification) require it last 100,000miles in ordinary use and 50,000miles for heavy use.
Auto gearboxes in cars are very similar to bike gearboxes.
I use the same stuff in my forks (its equiv 7.5w) and it retains viscosity better than any fork oil over seen at high temperature (viscosity index). I also use it in my clutch reservoir. One oil to rule them all!
I find Rotella T6 to be a bit too heavy and ATF a bit too thin. I know this will be sacrilege to many of you but I have been using a 50/50 mix of Rotella T6 and ATF and it works great and it is inexpensive.

Bingo, same here. Change it when it gets jerky, and you can adjust the ratio to suit your preference on clutch action (thicker or thinner). Plus, ATF has really great detergents to help keep everything clean. AND it's cheap (just like me!).
