Its about time for me to add some 2 cycle oil to my sons 05 SP 90. I have pure polaris premium oil and the gold. As I dont know what they put in it which one do yall think I should use. It will be mixing with what is already in there. I didnt know if it was okay to mix as long as they are both pure polaris brands.

Since both are Polaris oils, it's probably ok to mix. But just to make sure, you'd probably want to run your current oil near dry. Then, pour in other in. If you are very worried, run it near dry, pour out the little amount in the bottom of the OI tank, then pour the different stuff in. Don't worry about draining the lines. Getting an air lock in the pump or lines isn't worth it. Just pour in the tank - when the tank is near dry.

Hope this helps...
