I usually just use 87 octane and have not had any issues. Is there any benefit to using 91 octane? Would I notice a difference?

run 91 just to be safe! especially if you have a cdi and advanced ignition timing. Octane ratings are basically a measurment of a fuels resistance to "knock" or pre-ignition. Higher octane fuels are safer for engine internals, but rarely make power unless you're running a higher compression ratio, or forced induction........

my 2 cents........

Maybe I'll try 91 next time I'm out. See if I notice anything. Do you guys think using 91 would be better for the engine in the long run?

Heres my 10 cents because my 2 cents is free 91/92 if you can get it. I run AV gas in my banshee and 91 in everything else, **** even in my generator. You probably won't notice any power improvements. 8)

octane

think all the lil manuals u get with toys say to run 91 shoot in cali 87 at 2.67
versus 91 at 2.87 if u run lets say 20 gallons for a weekend thats only 4 bux difference for better running gas and no chance of pinging or preignition. save money where it counts not buying BRP"s stuff LOL

octane

91 here all my bikes and toys get it, I run 110 in my YFZ450 I like the smell also. I was thinking about running it in the rhino probably just a waste of money. Not sure if the high octane would be hard on the motor. Also when I run the 110 I use leaded I here it lubricates better but not sure.
