Ok guys, I am just wondering what octane of fuel everybody is running in your General?

Ok guys, I am just wondering what octane of fuel everybody is running in your General?

motor has 10:1 compression. I run the highest grade I can get.

No alcohol in Alaska. Not afraid to run regular but premium mostly. For 10 gal fill ups it's not a big economical decision. Like rusty said. Highest you can get, but its ok to run regular.

I wish we didn't have alcohol in our fuel! I play with some old cars and these fuel blends are rough on everything from fuel tank to the tune ability of the carbs.

I run 93 octane, it's the only one around here that doesn't have ethanol in it.

 

[Rocklong]

All I can get is 87 without driving an hour and a half to the nearest place with 91.

first time i used regular gas with ethanol to burns weeds:frown2:very yellow looking in a white bucket,would barley light:frown2:and when i mixed it in my drip torch,hard to keep lit.

 

[icecap]

Definitely will be running the highest octane we have down here, 93

Beside the fuel type. What kind of mileage do you all get with your General. This weekend we were trail riding in the Black Hills of SD and we went through two tanks in 2-1/2 days. One day we started full and 8 hours later we were nearly empty. The Ranger 900 who was with us only went through one tank all weekend and they only have .5 gal more capacity. This thing seemed like a gas hog. I know I have a heavy foot in my truck but this I couldn't believe. Thoughts?

Anytime I can have that much fun for the price of 9 gallons of premium gas I'm good.
And since I drive a modified FJ? Piss poor gas milage is nothing new to me.

I think I am getting about 13.5 miles per gallon and I spin those tires in the sand all day on every corner. I am not 30 anymore but I ride pretty hard. The only thing that slows me down are blind corners on two way trails. >

the owners manual says 87 so that's what i run, anything higher would be a waist of money and more than likely bring your mpg down along with a little loss in power, higher octane is for higher compression motors

 

[icecap]

The fuel octane discussion can legitimately go on forever lol

 

[Kenny G.]

Calls for 87 octane doesn't it? 1080 miles-14.88 mpg. 87 octane

 

[bullet112233]

I agree, high octane in a stock motor equals waste.

 

[Trapper]

I would think the mpg would be like my truck which has a computer to measure mpg. Mine changes by about 2 mpg depending how hard I push my right foot. >

I would really like to know how a higher octane fuel would result in a lowere mpg and a loss of power.
Also what is your definition of a high compression motor?
This motor is a 10:1 motor which I consider high. Of course I'm a car guy so my comparisons may be misguided. Most everything these days has a knock sensor that will at sensing a knock will retard the timing however that results in a loss of both powere and mpg. Also the ecu likely has a small window in which it can't retard the timing after that she's free to destroy herself. Altitude and ambient temperature will contribute to preignition. I run mostly in the low desert. Hot and low altitude. I'll play it on the safe side since I would never hear the preignition until the motor is destroyed.

Rusty nut the points you make are solid. I would like to here from Polaris why they recommended the rating they did. 10-1 is a high compression ratio by normal standards, but their reasoning I would like to know.

For many years premium is all I buy for all of my small engines. The cost difference is very marginal for the performance and longevity of your engine and fuel components. I bought a new 2000 Cevy 3/4 ton 6.0 liter gas engine and if I ran 87 octane it would ping. Go cheap on fuel and pay the difference down the road. Don't take my word for it search on the Internet and you will find plenty on low octane, ethanol and alcohol fuels. There is a reason why when you buy quality machines such as Stihl or a performance automobile they say only to run 91 or above.

higher octane equals less combustible, so a vehicle that recommends higher octane usually has a compression of 11:1 or higher for a less combustible fuel that can be compressed more.......remember there is a difference between combustible and flammable
