Forgot to add, I cant be the only one who thinks this way. My Polaris dealer also stated that you had to completely flush the oil system before going to synthetic.

 

Well I have an addition to be added and admit that the rumors floating around (at least for me) were wrong. I did some extensive research about Mobil1 since they have been making synthetic for a long time and here's what they said. " Our supersyn oil can be mixed with conventional oil, although the effectiveness will be reduced". I admit I was wrong and was mis-understood. My wife has been in auto parts for over 10 years and is a store manager and she even thought the same way I did. I am gald to find out the truth, though, because as they say "KNOWLEDGE IS POWER". Thanks,Chet. So Jtrundle, go ahead and do it.LOL Bubba

I service polaris atv's and the two stroke polaris oils are compatiable.(we regularly mix syn.and non syn blue)just be sure you stay with the Polaris oil.We have a 87 250 Trailboss that has never had the head off the motor. It is switched to Polaris Gold synthetic.
