Can't find info on the Valvoline 4 stroke 10w-30 version only 10w-40 and 20w-50, can you either take a nice pic of the back of the bottle and or post up all the "Specs it meets" (look for things like "JASO MA / JASO MA2")
I would just use any oil that meets the "Wet Clutch Use specs" ("JASO MA/MA2")... I can find Rotella for cheap, so that's (usually) what I use
