I prev used regular mobil 1 in my st1100 and never had any clutch slippage with it. Has anybody tried to use ref Mobil1 in their rocket to see if they get any slippage or not??
If the oil says "energy conserving" it will have friction modifiers and may cause wet clutches to slip. I don't think any oil over 10w-30 has these additives so you should be safe. I used auto Mobil 1 10w-40 for 11 years on my Sprint with no problems and no wear.
