I got a 2000 250 TrailBlazer and ive had it for about a mounth and i ride it kinda hard but i havent filled it up with oil at all i filled the gas tank up about 3 times so far. Do i need to change oil or how often do i need to fill it up? and a good brand? any help would be great thanks

 

Stick with the Polaris stuff. Running the synthetic wouldnt hurt. The TB's dont use much oil. You should only really have to fill it up maybe twice a year. Dont be alarmed
