Depends on afew things, if there is any types of fuel savers on the vehicle, if the engine has decent compression, if there is any sludge build up and what not... id say tho probably 30-40min... maybe even longer, my Dodge Spirit with a 2.5 can go probably about an hour or more, idling on a gallon of gas.
The duration a 350 engine can run on a gallon of gas at idle varies based on several factors, including engine condition and idle speed. On average, a small block Chevy 350 engine consumes about 0.5 to 1 gallon of fuel per hour while idling. Therefore, you can expect it to run for approximately 1 to 2 hours on a gallon of gas at idle. However, actual performance may vary.
Until it overheats, runs out of oil or gas, or has a mechanical failure.
To save gas, it is better to completely shut off the engine rather than allowing the vehicle to idle. This saves about 5 percent more gas than idling.
Approximately 5,000 gallons of air are needed to burn one gallon of gasoline in an internal combustion engine. This air combines with the fuel in a precise ratio for efficient combustion to power the engine.
2.5Oz per gallon of gas
Depends on what engine it has
Because the engine is running. Shut it off or give it gas and it will not idle.
6.4 ounces for each gallon of gas.
It varies widely. There is no single answer to your question.
Check the alternator.
you will have a bomb. your engine could explode from the increased compression of a diesel engine
It is not supposed to.
