Thanks the reason I ask is, sometimes you can't get the good stuff and I would hate to get in that situation on a trail gas station at any point. Ill use the good stuff when available.You do not NEED to use it, but I wouldn't use anything other than premium. It is recommended. Using regular will primarily reduce performance only, but using nothing but regular all the time will leed to more engine "maintenance" if ya know what I mean [/b]
I can not beleve that reg runs cleaner then prem any time I don,t care what it,s running. Prem will always run hotter then reg so how can it dump exc gas in the pipe?[/b]
Great answer! You're info is what I assumed everyone on the forum knew already, hence the short post I first gave simply suggesting premium as that's what his engine is designed to burn.You obviously do NOT understand OCTANE
the higher the # the COOLER the burn
This subjects make me laugh everytime someone says something ignorant
I was going to respond after the 1st reply but refrain to do so
as I was not sure if the sled in question was recommended FROM the FACTORY to run 87oct or 91
But as always you will get the ignorant statements aka premium burns cleaner,premium is hotter etc etc etc....................
Point being if the sled is made by the factory to burn 87oct burn 87 oct anything higher is a waste of $$$$
BUT if it says run 91oct by all means run 91[/b]
I gave my answer based on what I know: Polaris engines are designed to burn premium gas. That's why I recommended it. Any engine that's designed for 91 octane can burn 87 octane and vise-versa, but if it's designed for premium, you're better off burning premium. Polaris sleds are designed for premium; burn premium. I've mentioned many times before that the Fusion does not like regular, will not run properly with regular, runs great with premium. Regular gas in the Fusion results in the same as adding water to the tank, which is not good.
Premium also allows the engine to run cooler, as it ignites faster. ...............[/b]
This is my point exactly. Read me words more carefully, man, lol. If it's designed for 87, don't run 91. If it's designed for 91, don't run 87. I do realize that Polaris does not require 91, but recommends it. In that case, I run what I know my machine runs best. When I tried burning 87 in my Fusion (just the one time) it did not run well at all, and regardless of what the computer is supposed to do to adjust the timing, it still did not behave properly. I'm talking it wouldn't idle as well, wouldn't warm up properly, and wouldn't even pull out of the driveway without sputtering. Was half decent when giving it a large amount of throttle though. I have never experienced this with 91, so I always stick with 91. Not all machines are this picky though, but I do get good mileage... I also have no idea if this has anything to do with the octane level I'm burning or not.Pepsi
Check it out, no matter where you end up, you'll see there is absolutely no benefit to running 91 in an engine designed for 87. Period.[/b]
