I work at New England Dragway gas shack and the unleaded race fuel has ethenol in it. Has been for a number of years. Non of the racers have ever complained about it, and only a very few even noticed so don't really know if there is a "fix" for any probs. We run it in our race car and have not noticed much of a decrease in power, or rubber deterioration. Ethenol in unleaded (or white gas as we used to call it) has been around for maybe 20 or 30 years. Always has been a controversy to some, especially in the early years (70's gas crisis) because they tried to make the blend too heavy.
PS. Methanol (alcohol) does eat up rubber gaskets and rings.

New fuel to fix the crap comming out of the pump
Given facts : 1.0 horsepower (hp) = 550 foot-pounds per second = 2545 Btu per hour = 745.7 watts = 0.746 kW
Kerosene (No. 1 Fuel oil) 135,000 BTU per gallon
gasoline 92 octane 125,ooo Btu per gallon
ethanol 84,400 BTU per gallonGal.
gasohol (10% ethanol, 90% gasoline) 120,900 Btu per Gal.
So: when we run todays std mix of summer Gasoline/Gasohol we get less Btus per gallon than plain Gas
125,000 Btu - 120,900 = 4100 less or 4100 / 2545 = 1.611 hp/gal
1 gallon = 128 Oz so we add 10% Kerosene (12.8 OZ.) to the present Gasohol mix to increase the Btu content say 10% of 135000 = 13,500 btus for the 13 oz addition.
the remaining 115 oz of Gasohol will produce 90% of its 120,900 btu, = .90 x 120,900 or 108,810 btus
therefore 13,500 + 108,810 = 122,310 mixed btu.
you can add more kero to get back to the old gasolinespower potential.
H.P. potential theory = 122,310 / 2545 = 48.04 H.P per gallon burned.
111 Oz of typical pump Gas
13 OZ #1 Kerosene
4 Oz Airomatic Hydrocarbon (Acetone or Xylene,or Tolune or Benzene) Octane and btu content exceeding gas,kero,alch even race gas- so its all a plus here to err on the more Ozs side.
A much more power producing mixture and also more stable in the tank. you need a few Oz. of Acetone or xylene to promote the mixing by lowering surface tension generally speaking. Plus the Kerosene has lubricating propeties.
and yes ive done the octane and heat of vaporization and dessity mix for 14;1 optimization.

We've had it for 25 years. absorbs water, cleans out the system(which did cause problems) attacked old original gaskets(sometimes) only real bad was made some of my cars die repeatedly at the stoplight in the summertime.

I just use Sunoco 104. No ethanol there.

I ran it back in 81 in my Charger2.2. A year or 2 later Chrysler had a TSB saying bad for the Holley 2bbl, and great for causing vapor lock! That car vapor locked on any gas in 40* weather!

The Sunoco 104 at the track has ethenol added. At least that is what it says in the finer print on the drum. The 100 also has ethenol added. They are the only two unleaded they sell.
