I have an 03 r6 and the owners manual calls for 10w-30 in colder temps, and 20w-40 in warmer temps. The warm weather is now upon us in Ontario Canada, and i'm due for an oil chance but i'm finding it rather difficult to find 20w-40 motorcycle oil. And when I do a general search, it seems like everyone is just using 10w-40 instead or anything other than the called for 20w-40. Am i missing something? Was there a revision update to the manual that calls for a different oil? Any help is appreciated.
