How many miles can you drive on one gallon of gasoline?
I just watched a movie where the lead character pays for 37 cents worth of gasoline. That made me wonder how far I could drive while spending as little money as possible. How many miles can you drive on a gallon of gasoline?

What a fun question! When it comes to gasoline, your mileage may vary (no pun intended).
The modern American sedan or truck has an average fuel economy of around 25 miles per gallon.
But there are several internal factors that can affect a vehicle’s fuel efficiency, including the following:
- Oil type changes the friction in your engine and can change your gas mileage by up to 12%.
- Maintenance can affect vehicle performance, thereby lowering or increasing gas mileage. A clogged air filter, for example, leads to higher fuel consumption.
- Tire or alignment issues can cause excess strain on your vehicle and lower your fuel economy. A properly aligned car with adequately inflated tires will have better gas mileage than a car with worn-out tires.
Your driving habits also affect fuel economy, including braking or accelerating quickly, speeding, towing a trailer, or driving in the wrong gear.
Winter idling
also wastes massive amounts of fuel. The traveling environment also impacts your vehicle’s fuel economy. Driving on hills and mountainous terrain, road conditions (such as stop-and-go city traffic or highway driving), and weather conditions (like high winds or snow) also waste or save gas.
It’s safe to assume that under a variety of circumstances, one gallon of gasoline allows you to drive between 20 to 30 miles. Keep in mind, however, that driving on empty is not recommended and you should avoid letting your fuel level drop below a quarter of a tank.
