Hi Is anyone using 87 octane in there 800Xc the reason I ask is the owners manual recommends 91 but the plaque on the back near the 2" receiver says 87 minimum. So I wondered what people were using?

My wifes Polaris runs on 87 and with the current prices I would rather use it!

I've only ever run premium.  I run premium in my others as well, my newest Polaris (a 2009) recommends the 91 also. 

Thanks my wife Has the 2021 Polaris 570 trail and dealer told her 87 is fine and manual confirms it, I was supposed to get the touring 1000 Polaris but hard to come by in GA on top of the shortage, the manual for that says 87 is fine for that as well

So it's a bit annoying I only get 18mpg but that is off road adventure playground. I would like to do the Hatfield McCoy touring and need better mpg
