The internal combustion engine converts heat to motion or kinetic energy. Since ethanol has less "heat" than gasoline per gallon the fuel mileage will be less. Heat content of conventional gasoline = 115,500 Btu/gallon
Heat content of ethanol = 76,000 Btu/gallon E85 is a blend of 15% gasoline and 85% ethanol so you can expect a drop in MPG of 20% or more.

What is the gas mileage on a 2002 Chevy Tahoe?
www.fueleconomy.gov The Tahoe should get between 12 and 18 mpg on gas or between 9 and 12 mpg on E85 if you have the flex fuel version.
Does the flexible fuel vehicle get less mpg than a non flexible fuel vehicle?
If you are using E85 fuel yes it will get less mileage. If you are using regular unleaded there will be no difference.
What MPG should a 2002 1500 5.3 4wd suburban mine get 10mpg highway what can i do to help it e85 is worse?
I would have the vehicle inspected by a mechanic who is familliar with the engine. 10 mpg is NOT anywhere close to what you should be getting even with E85. My 454 Suburban gets 10 mpg with leaky injectors and a bad fuel pressure regulator, and only 9 towing 9000 lbs. And 8 mpg with those problems on E85. The 5.3L is much more common to get 14-15 on E85 highway, and 17-18 on gasoline highway. Typically 15-20% is the loss in mpg with E85. And a well optimized flex fuel vehicle will only lose 10%. A purpose built ethanol only vehicle will typically have no change and could see an improvement in mpg.
Is gas mileage better with E85 or Regular gasoline?
Gas mileage is way better with regular unleaded gasoline over E85.
Can you use unleaded gas in an e85 car?

E85
Can you run gas in an engine made for E85 fuel?
It is not made for E85 it is just designed to be able to use E85. You can use regular fuel and it will get better fuel economy in the process.
How does flex fuel improve gas mileage?
If you are referring to E85, from my experience using E85 actually lowers the fuel economy.
Can you use e85 gas in a 1971 Ford F-150?
No , the engines are not designed to use e85 in a 1971 Ford F-150
What is the gas mileage for a 1983 Ford F-150 V8?
Not much, 15 mpg or less.
What drop in MPG is expected with 15 ethanol gas?
The one difficult intricacy is that E85 fuel will give you lower fuel mileage. In a car that would typically get 20 miles per gallon, you might get 16 or 17 miles per gallon on the E85. An October 2006 report from Consumer Reports studied the fuel economy of a 2007 Chevy Tahoe, a flex fuel vehicle that can operate on E85. The study found a decrease in fuel economy for all categories. "Overall fuel economy on the Tahoe dropped from an already low 14 mpg overall to 10," the report read. "In highway driving, gas mileage decreased from 21 to 15 mpg; in city driving, it dropped from 9 mpg to 7." The report also found that the fuel tank of a flex fuel Tahoe depletes sooner than that of a non-flex fuel Tahoe. "It (Consumer Reports study) found that it (Tahoe's driving range) decreased to about 300 miles on a full tank of E85 compared with 440 of gasoline," the report concluded. "Motorists using E85 would have to fill up more often."
