Then there is ethanol. When ethanol is blended into the gasoline the mileage decreases. That is, it takes more fuel to travel a given number of miles on ethanol blend than it did on undiluted gasoline. If the amount of ethanol added is 10% as it is, and the decrease in mileage is 15%+ as actually is, the ethanol actually increases the amount of gasoline consumed.
The net result is an increase in the amount of imported gasoline as a result of blending in ethanol.
That is what I have noticed — roughly a 15% reduction in mileage with 10% ethanol.
I hate the stuff, and I am extremely prejudiced against those idiots who forced that crap on us!
Every chance I get to bad mouth an environmental whacko, I do so.
They and the PC Police will be the absolute ruination of this country.
More to the point, I’m keeping my 1990 Cadillac Fleetwood Brougham. When it needs repairing, it’ll get repaired.
I’m averaging 17.8 mpg over 126,600 miles of combined highway/city driving, and 21 mpg on the highway is not at all uncommon. And that is with that #%&@ing ethanol!
Plus, it is a large, comfortable car. A keeper!
