What Octane are you running?

[chipworkz]

So my question is what octane rating is everyone running?
I know you don't need to run higher octane fuel than needed if you don't have a pre ignition knock problem.
The KFX is 12:1 and recommends 91 or higher.
I have only taken it out once so far with standard 91 octane premium and didn't hear any knocking. Has anyone had any problems running premium pump gas?
Thanks

It should be just fine running on premium pump gas.

you should have no issue running the premium fuel which is 93 around here.

I have tried every type of high-grade gas in western KY on a 05 WR450, 04 450R, 05 Rancher 350, and KLX 125 and the Shell 93 V-Power is the BEST. They all ran like **** off every other brand I have tried eccept the Shell. I don't know why but they do best off the Shell 93.

i would run 94 if i had one just because it is so high compression. just to be on the safe side.

93 is as high as it goes around here.

I believe it was a Shell gas station that I was @ recently, & their Premium 93 gas was Non Oxygenated,.....No ethanol gas

Hmmm the only gas avail. around me close that is not ethanol blend is only 89 octane? Are you saying that this engine does not like ethanol?

In older cars (carbureated)
&
High performance cars
They seem to me, & others I've talked with,
to prefer non ethanol gas premium gas.
I'm going to try some Klotz race fuel & pump gas mix this weekend.

If you want to pay $10 a gallon for gas, more power too you. Klots was $50 per 5 gallon can 7 years ago.
