so before i heada out and buy the V300, i would like to ask if my engine was using 10w50 , is it safe to change it to 10w40 V300?
ive read post saying dont use full or semi to run your engine in? does that means when your engine is freshly rebuilt
as for the gear box (its whining) -Redline lightweight shockproof 75w90?
what for the diff ? (it whins too) - ????????
