My miles per gal. went down over 12% with 10% ethanol,
on long trips, 300 miles and above. I have checked this
going and coming on several occasions. Apparently using
more gas plus the ethanol. Another gov’t screw up.
From my younger days, I remember that carb. jets size had to be increased, to run alcohol in racing engines.
So true. Not mentioned also is the cost depletion of water from underground aquifers.
I read somewhere that the government is considering raising the maximum ethanol content in "Regular Unleaded" from 10% to 15%. You can bet the price per gallon won't come down - and the cost per mile traveled keeps going up as fuel economy drops.
BTW, this is why none of the hybrids run on E85.
