Ethanol in New York Gas Too !
Archer, Daniels, Midland Corporation gets a HEAVY subsidy for making Ethanol which would otherwise probably not exist commercially. They add Ethanol to our gas here in New York, or so all the gas pumps say. My understanding is the ADM company gets about 3 bucks a gallon from our tax dollars for producing and selling it before they actually sell it to the oil company's who add it to our gasoline.
My 1987 6 cylinder 4.0 litre Jeep Cherokee Laredo (AMC) got 21 MPG at 50 to 55 mph, lower mileage at higher speeds, using premium fuel.
The 1994 Grand Cherokee limited (Chrysler) with a 3.73 : 1 rear end ratio and the 5.2 cast iron V-8 gets 20 to 21 at 50-55 MPH, at 70 that drops down to about 18.5 to 19 mpg. If I replaced the 3.73 with lower ratio I could up the mileage, but loose a lot of power at the low end. Again Premium gas.
The 2004 Grand Cherokee Overland (Daimler) with the 4.7 alloy V-8, and Quadra Drive 2 system gets 18 on the highway at 50-55. I've only had it two years, and drive the 94 most of the time so I haven't yet tested the 70 MPH mileage. I just passed the 3000 mile mark on the odometer. Next week I'm taking it on a trip and will measure it, and get back to you. Premo gas too.
I also use 100% synthetic oil in all these engines, and transmissions, and differentials, and transfer cases. That is a plus for my mileage as well.
I could spend more to get a Hybrid, but I'd rather drive the Jeep and put the Hybrid upcharge into gasoline. Besides the Huge battery in those rides will need replacement if the battery in my cars is any indication, and what a battery case that's about four feet square will cost to replace, I'd rather not learn.
