What is the best speed to drive to get the best gas mileage?
55-65mph
The Energy Saving Trust says that the most efficient speed you can travel in a car in terms of achieving the best fuel economy is 55-65mph. Any faster, though, and the fuel efficiency decreases rapidly. For example, driving at 85mph uses 40% more fuel than at 70mph (oh, and it’s illegal too).
When to refuel when your gas tank is half full?
On the flip side, the less fuel you’re carrying, the better your gas mileage (at the expense of traction). Half full seems way over the top. I normally refuel somewhere between 1/4 and shortly after the low-fuel warning coming on. If I were out in the back of beyond I would always make sure I had plenty of fuel to reach the next filling station.
How many miles can you go with a full gas tank?
Turns out, the answer varies greatly with every car. As a general rule, most cars have about 2.5 gallons left in the tank when the gas light comes on. So depending on how many miles you get per gallon, you can probably go anywhere between 30-60 miles.
What happens when fuel gauge drops to 1 / 4?
This could be compounded by the fact that having the tank under 1/4 full, the fuel could slosh away from the fuel pump inlet point and cause it to starve for fuel. If the car runs totally fine with a full tank, my suggestion for the short term would be to just keep the tank over 1/4 full, which is good practice anyway.
What happens when you fill up your gas tank?
Normally, air flows through that tube while you’re filling and the gas keeps flowing as long as you hold down on the trigger. When that hole gets covered by gasoline (when your tank is full), a vacuum forms inside the nozzle and an automatic shutoff switch gets tripped, turning off the flow of gas with a thunk.

Why is there more gas in the tank?
Still, the folks who never fill up and run around on 1/4 or lower all the time will have more fuel pump burnouts as the fuel in the tank helps cool the fuel pump. More gas in the tank is more cooling for the fuel pump.
What happens if your gas tank is low?
According to Consumer Reports, gasoline acts like a coolant for your vehicle’s fuel pump motor. If your gas tank is very low, the fuel pump can suck in air. The fuel pump can then become overheated, which may lead to premature wear on the fuel pump, and eventual failure. If your fuel tank has dirt in it, it can become clogged as well.
Do you run your car with less than 1 / 4 of a tank of gas?
Personally, I wouldn’t intentionally run my car with less than 1/4 of a tank of gas, simply because it doesn’t save any money, it may damage the fuel pump (unproven concept, but why take chances with an expensive repair job?), and–of course–it puts you in greater danger of running out of gas.
