E-85 is a mixture of 85% ethanol and 15% gasoline. Alcohol (the ethanol part) is more corrosive to certain engine parts than regular gasoline, so some components on a gas only engine will not stand up to E-85. Also E-85 will drop your fuel mileage by about 20% in some vehicles because it has lower energy content per gallon. But remember, ethanol can help support farmers and the US economy rather than foreign oil exporting countries. The modern engine control modules (ECM's) on many newer cars make switching between gas and E-85 as simple as filling up with your preference. Just be sure to check if your car is a "flex-fuel" vehicle first.

Because that's how an engine runs. it can only ever rev up if you give it gas. no gas, no revs. more gas, more revs

What is the difference between a Gas engine and a Gas turbine?

gas turbines and gas engines are different in mechanic designes uses diffrent liquid for engine we use flemmable gas we use for turbine liquide flemmable but they need air both gas turbines and gas engines are different in mechanic designes uses diffrent liquid for engine we use flemmable gas we use for turbine liquide flemmable but they need air both answer by I dont think so. Gas engine works as the same principle of a petrol engine. And in gas turbine gas is burned and high velocity gas is passed through the turbine. A gas engine is an internal combustion engine and have no turbines.

What is the difference between gas compressor and gas turbine?

a compressor does work on the gas , raising its pressure and temperaturea turbine does the reverse , it expands the gas as it passes through the turbine, extracting energy from the gas to do mechanical work.For a typical jet engine , the flow track on a compressor is of a converging cross section while is it diverging for the turbine, which is as per gas dynamic laws.The Turbine does two things here in the jet engine, one ,it runs the compressor and two, expands the gas to the propelling nozzle which produces thrust by accelerating the gas upto its exit.

yes, because the ac runs off the engine and puts more stress on your engine and has to work harder.(work hard waste gas)

What is the difference between a Gas engine and a Gasoline engine?

Gasoline is made from petrol. Gas is made from the gas collected in the layer above the petrol. Gasoline is faster and safer. Gas is less expensive, but you can't put in a garage because it can blow or leak. Hope I'm helping you =)
