Hey guys.  Hope everyone is doing well.  I came across the following article today and figured I would share it.  It is talking about Ethanol in boat engines, but it is definitely worth looking at for our sleds, atvs, etc…

Rick, I agree that this is a major problem.  There are a lot of good products on the market that can be used.  The product in the article that you posted sounds like it is very good.  My suggestion is to consult with your local dealer and see what they have available, as I said there are a lot of good products for this problem.  I have been using NAPA brand, and that works for me.  Also another very good product is made my SPECTRO.  They make a lot of different products (oil-oil blends-wash-stablizers-etc.) that are some of the best on the market.
