Here's a general guideline for the fuel requirements of different Polaris Sportsman models:
Sportsman 450 and 570 models: Use unleaded gasoline with an octane rating of 87 or higher.
Sportsman 700, 850, and 1000 models (carbureted): Use unleaded gasoline with an octane rating of 87 or higher.
Sportsman 700, 850, and 1000 models (fuel-injected): Use unleaded gasoline with an octane rating of 91 or higher.
It's important to use the recommended fuel specified in the owner's manual for your particular Sportsman model. Using fuel with an octane rating lower than recommended can cause engine knocking and performance issues.
Always refer to the owner's manual for the most accurate and up-to-date fuel recommendations for your Polaris Sportsman.
