Is an automotive 10w-40 say like mobil one going to be ok for a wet clutch like I have on this bike? The dealer told me to use an oil made for a wet clutch. In the book it says not to use an energy conserving oil and it lists sf, sg, sh and sj. Would it be ok to use am sm oil? I know you can usually go up but just wondering since it has a wet clutch. Thanks
