It depends on a trailblazer 250 they have no crankcase oil but on a 400 water cooled scrambler they do so yes you need to change the oil with regular motor oil

No, you don't mix oil into the gas of a Polaris Trail Boss 350 4-stroke. It is a 4-stroke engine, and you do notmix oil with the gas.
There is no valves as it is a 2-stroke engine .
There is no oil to change in a two stroke engine. The lubricant is the oil that is mixed with the gas.
If it is a 2 stroke then use any brand of 2 stroke oil mixed to the correct ratio with gasoline.
well about 487.9 and 1/2 years
Hey, if im thinking right Polaris 250 s were all 2 stroke, no oil needs to be changed.
if you have to mix oil with the gas its 2 stroke or cycle and if you have to change the oil its a 4 stroke or cycle
