Ethanol fuel

[Allseasons]

I use shell 91 cause of the non ethanol


And reason why not to use ethanol, is the moisture it attracts and holds, along with the less Btu per unit

i fully agree Tex. And the environment a sled runs in is far more extreme than a race car.... Warm to cold and back again, the inside and outside of a tank is always sweating moisture.
My knock sensor works, from a pump I can’t run ethanol fuels, she puts me in limp, but my my compression is higher than stock. Shell 91 works, never had a problem
