Do you mix snowmobile gas?

With either AMSOIL choice, go with the prescribed 50:1 ratio. This is a very conservative ratio that will deliver clean combustion and the best possible wear protection in any 2-cycle snowmobile engine. Use this ratio regardless of the original oil/gasoline mix ratio recommended by the snowmobile manufacturer.

What kind of gas do you use in a snowmobile?

The minimum fuel requirements for Polaris snowmobiles are fresh quality unleaded fuel with an octane rating of at least 87. Do not use fuel containing more than 10 percent ethanol (E10). For maximum performance from a 600, 650, 800 or 850 engine, Polaris recommends the use of 91 octane fuel with no ethanol.

How does a fuel pump on a snowmobile work?

The fuel pump is driven by pressure/vacuum impulses from the rise and fall of the piston in the crankcase. If you remove the impulse line, the only fuel that will go through the pump is what gravity allows.

Is ethanol bad for snowmobiles?

Ethanol can destroy your fuel system parts. This was true a couple of decades ago but all snowmobiles since about 1978 use grades of plastic and rubber for impellers, floats and lines that are impervious to ethanol.

How do you mix a 25 1 2 stroke?

Usually the ratio is 50:1, that’s a little container of two cycle oil (2.6 oz) to one gallon of gas. To make 25:1 use the 2.6 oz two cycle oil to a 1/2 gallon of gas. That’s the simple way.
