Question What type of gasoline to use?

Hey guys, I just have a quick question. I use 91 octane fuel in all my snowmobiles and I was wondering if that is the appropriate type of gas to use in normal gasoline sleds. I hear premium fuel or the higher the octane the better. I rarely see higher octane so I dont know how much better I could do anyway. Thanks for all the help!

Sorry if this is in the wrong forum.

besides race fuel 93vpower is arguably one of the best street gasolines imo.

and you will have people telling you 87 is what they are meant for ,and they are ..... low octane is easier to light which is true . premium will hurt performance of a stock sled ...

ill tell you what ... al of ours run impeccably no cold start issues and my wildcat seems to really like it too .. vpower / interceptor . winning 2 stroke combo !

I use 87 or 93 octane depending on whats available. though I use the 93 most often because it's not blended with ethanol where i'm at.

no but you could without any probs at all. im saying if your not riding sub zero temps you do not need the low octane ... my plugs look better on premium sled smells better and sounds better to me.

next year my cats runnin sunoco gt110 at 6 $ a gallon

local lakes and trails only for that thing ..

Ok, I don't know this for a scientific fact, but according to the experts at Snow-Tech magazine in an article they published in the last couple of years, if your sled is tuned for regular gas, it will make more power with regular. Maybe your sled will 'run better' on premium, but you will make less horsepower. They say regular is 'hotter' than premium, and the only reason to run premium is if you have a high compression motor that will detonate with regular.

I run regular in my stock sleds and premium in my high compression overbore shaved head sleds. I'd love to run regular in them too, but they did detonate or 'knock' when I tried it.

There's no mistaking the power of the V. I put V-Power in everything. Best fuel for the streets.

cant fergit about timing as well ..... advanced timing needs detonation resistant fuel
