Anyone using Mobile 1 or equivilent? I've been reading the CRF450 posts and it seems that it's pretty popular. Some are running it in both sides (engine and tranny) or just the engine side. What are you guys running? Right now I've got the Honda Gold 10-40 wt. It is a petrolium/synthetic blend. The reason that I have 10-40 is that the guy behind the ECC parts counter said that's what to run. When I got home and double checked my manual I realized that I really should be running 20-50. DOH! Gonna change it out and I want to run the best oil I can find. Hep me, Pig Brutha's!
