    Fuel ratio and oil compatibility

    01 carb'd gtx 951 just purchased over the winter from Florida. Rave inspection looks alright. I'm gonna replace all the fuel and vent lines. Last owner claims he used a Yamaha synthetic 2 stroke oil at all times. I'm not sure if the full tank of gas / oil mixture will be compatible with the 100% synthetic oil of my choice. Fuel around here has 10-15% ethanol. Should I dump all the fuel and start over? Or should I run it close to dry then fuel up with my mixture?
    I have read some confusing and inconsistent things regarding this and need some help? Lastly, What ratio (premix) do you recommend? I have heard of some using 32:1 and others at 40:1. I am a recreational rider and looking for longevity not for 2 more mph or rpm etc.

    Are you sure the oil pump has been disabled? Mix XPSII @ 40:1, their recommendation. I'd dump the old fuel, and if the pump is still there, change the oil filter between the pump and engine when you remove the oil tank, flush, and install only XPSII.

    pump is gone. Oil tank too. It has been converted to pre-mix before I got it.

    If it were me I'd run Amsoil over XPSII. You use less (50:1, always use the oil manufacture's recommendation for their own oil), and the RAVES stay cleaner. Plus it's cheaper too. I run Dominator in my pre-mix skis. But they are highly modified.
