SAE 10w30 synthetic is a great choice.
Gears in transmission are bad .
Polaris has its brand of hub oil , which is not cheap . Ford ATF :automatic transmission fluid is recommended if you do not want to pay for Polaris oil .
Need the fuse location on a 2003 Polaris Sportsman 400.

how do u bypass the oil injection on a polaris 400 2x4 scrambler
There is not a fuse box on the Polaris 400. This machine has circuits and breakers which are generally located under the seat.
The 95 Polaris sport is a 2 stroke model, with oil injection. the oil tank holds about 2 quarts. it doesnt have a crank case level as its lubrication comes from the injected oil. though some models come with a balancer that takes oil. I suggest you get a Clymer manual , it will give you all the info you need and more about that atv.
