    whats everyone running for premix on powervalve motors

    I'm currently using yamalube at 32:1 since that's what's recommended,but I was thinking of switching to amsoil interceptor at 40:1 cause that's what I read a lot of people run,or since its a powervalve motor do I need to stick to 32:1

    I ran yamalube on my single pipe at 40:1. The triPle pipe ski is ran on amsoil dominator at 50:1

    I run Amsoil Dominator in my Lowell 1390.

    Interceptor is Amsoil's rec oil, while Dominator is supposed to be their race formula.

    Yamalube is a great protectant oil (that's why everyone swears by it for engine break in), the only issue is it produces a lot of sut when it burns and causes the powervalves to get gummed up and they'll stick open after many hours of run time.

    40:1 is easy at the marina. 1qt oil to 10 gallons of gas. (AMSOIL is best!)

    40:1 is the best from our testing... with a good oil like Klotz or Amsoil, you can go up to 50:1 if you like
