What type of gas ?

[Ruckzuck]

Just wondering your thoughts on fuels . I recently had my fuel pump die while out . People are suggesting that this likely happened from running Dyed premium gasoline. I'm not sold on this theory and just looking for opinions from others .

I have a stage 1 flash and run premium gas. No problems.

87 in the RZR.
91 (premium) in my stock quad
101LL (Av gas) in my fast quad
Whatever is close by for the ATC.

I always run 91 or better.

I run premium

I don't think dyed fuel would cause any problems. I only run regular gas in all our SXS's and premium in my quads .

not going to get in a pissing match so short n sweet if you run a higher octane than your eng needs your wasteing it. higher octane slows the burn down to stop detonation if your eng doesnt need it and you run it the slower burn goes out faster and isnt used up. the amount lost is very small and you most likely wouldn't feel it and it also emits more smog.... i took a class and this was proven on a dyno and emission mach. i know many of you say your eng runs cooler wile this is min this is because of the raw unburnt fuel that could cause washed out cyl... this is my one and only comment on this. as it has been proven a fact on test equipment so fight amounst yourselfs as i wont comment.

You are 100% correct JC8 !!!!

I use 91 in my Mav cause that's what it says on the sticker by the gas fill, it may be because the turbo has lower compression Pistons ?
