Bob, I think you will find that dragsters run on methanol, which is a different 
kettle of fish.
In Australia we have E10 (10%) supposedly 94?? octane. I won?t use it in my 
Healeys as it is rubbish (2c per litre cheaper than 91 unleaded). One  small 
fuel company makes E85 which a friend uses in a Datsun 1600 (510) race car 
fitted with EFI. He had to increase the fuelling by 30% from that for 100 
octane Av-gas to obtain the same hp figures. The exhaust stink is sickly and 
sweet and unbearable. Might be great for the environment, not good for humans

I use 95 or 98 octane in all my cars. For the low mileage they do, the extra 
expense is negligible.

I totally agree with David Nocks comments in his recent email

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

('alternate fuels,' not 'alternate facts')

 

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.

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.

 

Best regards,

Jim
