GREAT oil for cars!! Have you noticed they are switcing teh GT-1 to a blend also? Makes me wonder if it alwase was?....hummm,,,,?
From what I have been told by mechanics is that the additives that are needed for a 4stroke with a wet clutch system are not found in conventinal motor oil. so they (bike and automotive mech's) along with the cycle shops HIGHLY recomend not to use std. automotive oil.
stil tryin to find an opinion on the 20w50 blend im runnin right now, my guy at the shop said it would be ideal if i run hard (which i like to think i do) he isnt a dealer , just a "mom and pop" so i hope hes not tryin to set me up for repairs with a bad recomendation !!!
BEL RAY THUMPER 20W50 for 4 stroke
Anybody use the Valvoline 4-stroke stuff available at Schuck's and everywhere? I talked to a guy that was supposedly told by a dealership that Valvoline makes oil for Yamaha. You know how that goes, but seriously...anyone run the stuff? I ran it in my Vmax m/c when I had it with no problems.
Yeah, I run the Valvoline ATV 10w-40. I can get it at the auto parts store and its only $3 and some change a quart. I like it and been using it for some time now. I got turned off on synthetics after my clutch started slipping (on my 400EX).
I am running Yamalube 20W-40. That is what the manual said to use and it is also what the dealer said to use. You can use a normal 10W-40 but you need to make sure that it is ok to use for a wet clutch. If it is not, then your clutch is going to start slipping.
