Just purchased a 1999 GP1200xl with 57 hours, with rebuilt carbs. The PWC mechanic I bought it from says to run 2 onces of Ringfree per tank of gas. I was told to use Ethanol free gas which is available near my Lakes. Plus to use Yamalube for the oil. My Yamaha dealer says they have not had nor had anyone request rigfree from them in over two years. So they don't carry it. Is there a alternative? Plus Yamalube is $35 a gallon is there anything similar for less that availabe in the USA?

Thanks for any help!
