Just found O'Rielleys/Kragen Auto Parts carries several grades of Mobil I 100% Synthetic Gear Oils 75W/90, 75W/140 I believe, but as I have a Sporty, I choose not to use 100% Synthetic Gear Oil because oil wetted clutch slippage and wear may occur with common lubricant used in chain case and tranny.
