P500 Quick question on fuel

[906UP]

All of our snowmobiles are 4 strokes now, they run on recommended 89 all winter but I will fill them with premium, 91 or 93 (non-ethanol) depending on gas station, before we park them for the summer. The sleds sit for a lot longer than our ORVs..... 8 months or more.

Here is a link to the best video that I have found that explains the purpose and benefits of higher octane gasoline. It is from Australia but is applicable worldwide.

As for the other claims about the benefits of using premium fuel

Enjoy!

Is it a ping or do you need to adjust the valves?

I wondered this as well, the P5 is such a noisey little fkr I'm not sure you could hear spark knock

Pretty sure it's ping. But I agree, they are noisy mutha's
