94 XLT Polaris 580 Tripple, what Octane?

I just purchased a Polaris 94 XLT 580 Tripple, and I want to run the proper gas. I asked the previous owner, and he said he ran low, mid, and hi 92 octane. Kinda left me guessing. I read some past threads here on Octane, and really got information directing me everywhere!

Did read that the XLT 94 shouldn't be running anything with ethonal in it, is this true?

So, I figured I'd ask some Polaris guys that own a 94 tripple for what should be run in my sled! Don't have an original owners manual to look at either...

Hey, thanks for any help on this...

Kevin

I have a 1991 RXL and I just run whatever gas we have in town. Just make for sure it has absolutely no ethanol in it. My cousin's friend ran ethanol in his brand new Doo and blew it up. My sled runs better on premium, but it's not necessary. Add in some Iso-Heet every once in a while...it helps keep everything clean and you should have no problems. I love the old triples!!! Keep her runnin strong.

If it's stock just run a good 87 oct! If it has different heads and a timing key then 91!

I run a 95 and mine likes 91 but as long as it's not ethanol I'll run it.

I looked and asked at my local gas station about ethanol, it didn't seem to have it. I've never paid much attention, is this something that they mark clearly on the pump, I'm assuming it would be a law to do so?

not sure where you are located but here in wisconsin almost all gas has some percentage of ethanol. meant to stimulate the corn industry here. i'm sure i run it all the time, never had any problems. it will say on the pump though.

I'm going with the 87 octane. It calls for a minimum of 87 octane in the manual, so that would indicate to me that using higher would be fine too. It is a very confusing issue to me. Maybe it doesn't matter much.

only reason you would need to use higher grade is if you have different heads like kccats specified. sleds are designed to run on regular unless otherwise specified

My '91 is pretty boggy running on just regular gas but with premium it runs like a top and has no hesitation at all. It runs perfectly fine on either one, premium is just a little better, so that's what I usually run.
