Yes you can, infact you will get better Fuel mileage than E85.
less wind resistance, better fuel mileage
Less weight = better fuel mileage.
Better fuel mileage and cleaner emissions.
I would say the best fuel effecient cars would be the flex fuel cars.They get great mileage and cheap to fill up.
RAV4 vehicles feature off roading, high fuel mileage, and Flex fuel, which allows you to use up to 85% ethanol in them. They also have a spacious interior.
The less weight, the better the fuel mileage.
Cars get better gas mileage on the highway because they can maintain a more consistent speed, which reduces the amount of fuel needed to overcome frequent acceleration and deceleration. Additionally, aerodynamic drag is lower at higher speeds, further improving fuel efficiency.
So that the cars not make enviroment worse
Most car companies are going in the direction of creating fuel efficient cars and trucks, but you might want to contact Toyota at their website Toyota.com and ask them when they will start production on flex fuel cars. GM currently has vehicles that are flex fuel so go to Chevy.com or GMC.com and look at what flex vehicles are out on the road currently.
Less weight equals better fuel mileage. Crampled?
Newer cars are geared towards being more fuel efficient than older cars. Cars made in 2012, depending on engine size, will likely get much better gas mileage than your 1993 Buick. These older cars were geared more towards comfort and power and less towards improved gas mileage.
