Agreed. To put some rough numbers to it ethanol has approximately 60% of the energy content of gasoline (petrol if you prefer). Methanol is even worse at around 55%. To produce equivalent work you need to burn approximately 4% more 10% ethanol fuel. The reason
alcohol is used in racing engines is (as noted below) that its higher octane rating allows huge increases in compression ratio. To achieve power gains on alcohol requires a massive increase in the amount of fuel used. A single run for an alcohol powered dragster
may use 5 gallons of fuel or more. Other advantages to alcohol burning are that mixing the larger concentrations of alcohol provides a cooling effect that improves volumetric efficiency and that alcohol contains some oxygen that promotes better burning.

<div>Ethanol has a much lower energy content than gasoline, hence the lower mileage with gasahol. See here:<br>

<div>It does, however, have a higher octane rating allowing the huge compression ratios in dragsters and other racers; which is what produces the massive power in those engines.<br>

<p class="MsoNormal"><span style="font-size:12.0pt; font-family:"Times New Roman","serif"">The correct AFR for alcohol (ethanol) is around 8 to 1 versus gasoline at 14.7 to 1. Switching to 10% ethanol should equate to about a 5% richer mixture. Ethanol produces
more power than gasoline – hence alcohol race engines but much more fuel required. Your mileage will suffer.</span></p>
