    oil for 4-tech supercharged ski's

    I was curious exactly what is the best oil for the 4-tech supercharged ski's both of my skis have the Riva clutch washers. I have been reading about amsoil but was not sure exactly what the correct amsoil type to use in these ski's.
    Thanks to anyone that can help me out.

    This is what most of the people are using the AMSOIL 10w-40 Synthetic Marine Oil

    How many of you guys run this oil in your supercharged machines? I've seen this add a thousand times but have always been skeptical of running anything other than the BRP recomended products. If this is recomended by other well known forum members I will order a case....

    LOTS of us use Amsoil WCF 10w-40, I've used it since 2005 in my doo's and my vehicles since 1990. This topic has been beat to death on this forum, and you will find nothing but positive results.

    mobil racing 4t is good stuff too and used by quie a few people with high performance setups however its not cheap.

    duke recommended Valvoline to me a while back as well and said its fine it you change it regularly ( due to GIO etc...) and best of all its cheap.

    Many of us run valvoline 4-Tec 10-40 motorcycle oil from autozone. Half price through the end of the month.

    The reasons they recommend thier oil is one they make money off you buy selling thier oil,two,back in the day when Scer clutches were ceramic you had to use a mineral based oil, now that we have metal clutch washers you can use any oil that is JASO MA rated and it will work fine and you will have NO issues..

    If you go with the Valvoline right now it is about 3-4 dollars a quart cheaper than the BRP oil...
