The guy peddling atv and motorcycle specific oil at the stealership will tell you there is a huge difference...LOL. In reality, the only auto oils you wanna stay away from is 5w-30 and 10w-30 because they have "energy conserving" ingrediants that some clutches do not like.

Several years back federal law required gasoline makers too start producing "cleaner" gasoline. The only problem with the cleaner fuel is that approx 10% of fuel economy was lost. Govt applied pressure too oil companies and passed laws that would mandate oil companies come up with a "slicker" oil that creates less friction. This was an attempt too get back some of the lost fuel economy. ALL conventional oils that are 5W-30 and 10W-30 are of this formulation. All of these oils have a "sunburst" designated on the front of the container....usually the lower right. I have rode my Raptor with 10w-30 oil no problem....but SOME clutches do not work well with the energy conserving oil. I always ran Dexron 3 auto tranny oil in my 2 strokes with no probs. Shifts like butter too.
while we are on the topic. The Guy at My "stealership" told me last week when I bought my Raptor that I only need to change the oil once a year..... How the hell is that true? Can anyone back up this argument.?
