You would get a very small amount of better mileage in the second half of the tank due to the fact that your engine has to haul a half tank less of weight around.
The functioning of the engine doesn’t change due to the amount of fuel in the gas tank, except when there is no gas in the gas tank.
Does your gas last longer with a full tank?
The wait until the gas tank is almost empty before filling folks proclaim that you get better gas mileage due to less weight. Well, they’re right, but how much of an advantage? If you have a 15 gallon tank, that’s 92 lbs less of weight and your gas mileage will definitely be better.
Is your car more fuel efficient with a full tank?
If you drive from full to empty you are carrying on average a half a tank. So the average weight savings is 1/4 tank or about 30 pounds. That’s about .75% weight savings for a typical 4000 lb car. That might get you from 25 mpg to 25.19 mpg assuming mileage is roughly inversely proportional to weight.
Do cars drive better with a full tank?
Cars have better gas mileage the fuller the gas tank. As the tank empties out, more and more gas will vaporize to fumes to fill up the volume of the tank above the liquid. That means you have less and less gas to burn.
Why is my car not getting good gas mileage?
Bad Gas Mileage Causes: Incorrect tire pressure is a common cause of bad gas mileage. Having bad oxygen sensors and air filters can reduce your gas mileage by up to 20%. The oxygen sensors help keep the proper mixture of air and fuel, and having this off balance can be inefficient.
What speed is most fuel efficient?
Increasing your highway cruising speed from 55mph (90km/h) to 75mph (120km/h) can raise fuel consumption as much as 20%. You can improve your gas mileage 10 – 15% by driving at 55mph rather than 65mph (104km/h).

What is the best time to fill petrol?
1) Always fill petrol when early in the morning or late in the evening when the climate is relatively cooler, the density of fuel is highest when the climate is cooler.
Is it better to pump gas fast or slow?
Pump a Little Slower
Most nozzles are set to pump gas at three speeds – slow, medium, and fast. Pumping at high speeds releases more gasoline vapors, which your nozzle pulls back in with a vapor recovery system most pumps are outfitted with. This means you could be paying for more gas than you receive.
Is it bad to let your gas tank run low?
The fuel pump has the function of pumping fuel. When there’s not enough gas in the tank, the fuel pump doesn’t get the same level of protection as it would otherwise. If you run the car low on fuel consistently, you can wear out the fuel pump prematurely, over-stressing it and making it hotter.
Is it better to fill your gas tank all the way?
Don’t fill up your tank
Each gallon of gas is 8.34 pounds, so depending on the size of your fuel tank, that means you could be saving 60 or more pounds just by filling up less, which in turn means using less fuel to schlep around all that extra fuel.
What happens if you overfill your gas tank once?
Overfilling the gas tank can cause liquid gas to enter the charcoal canister, or carbon filter, which is designed only for vapor. Gas in the system can affect your car’s performance by causing it to run poorly, and damage the engine, he says.
