Theoretically yes. The reason is that with less space in the top of the tank, there is less room for evaporation of the fuel in the tank, so you have less fuel turning to vapor in the tank. At least that is the theory.

No, the amount of fuel in the tank has almost no effect on fuel mileage. If anything the more fuel you are carrying around the more weight you are carrying around which will actually lower fuel mileage. Gasoline weighs about 8 pounds per gallon. But that little bit of extra weight is really meaningless. As to evaporation it is not a factor as the fuel system is sealed and any evaporation is miniscule. It is beneficial to fill your tank once it gets to 1/4 full. There are two reasons for this. Air contains moisture the more air in the fuel tank the more moisture in the fuel tank. Secondly the fuel pump uses the fuel to help cool itself. The less fuel the more chance the fuel pump will overheat which will shorten it's life.

How do you figure miles per gallon?

Start with a full tank of gas. Note the mileage on the odometer. When it's time to fill up, note the ending mileage and the number of gallons it takes to refill the gas tank. Subtract the ending mileage from the beginning mileage to determine how many miles you went on that tank of gas. Divide that number of miles by the number of gallons it took to fill the tank.Example:Starting mileage: 12,000Ending mileage: 12,360Total miles driven on tank: 360Gallons of gas to refill tank: 14So, 360/14 = 25.7 miles per gallon

How do you figure out miles per gallon?

Fill your gas tank to the top and write down your mileage (save it). Drive you car until you have about 1/4 of a tank of gas left. At the pump write down your mileage and fill your tank up to the top again. Subtract your start mileage from your finish mileage. Take the number of miles you drove and divide it by how many gallons of gas it took to refill your tank to the top. This will tell you how many miles you get to a gallon of gas. Example: Beginning mileage; 90,000 miles - Finish mileage; 95,200 miles Gallons used; 20 gallons 95,200 -90,000 ------------- 200 miles 200 miles divided by 20 gallons = 10 miles to the gallon

You feel mileage has been altered how do you check?

Fill your car's tank all the way full. Drive an exact number of miles. Fill your car's tank again and note how much gas was required to refill it. Divide the number of miles you drove by the number of gallons of gas. For example, if you filled your tank and drove 15 miles and then refilled your tank by adding .5 gallons of gas, you mileage would be 15 divided by .5 = 30 miles/gallon.

How do you find out how many mpg your car gets?

Go to the gas station and fill up the fuel tank.Record the mileage, before even pulling away from the pump. We will call this Mileage A.Drive normally until the tank is less than half full.Fill up the tank again (preferably at the same station using the same pump as pumps may be calibrated differently). This time, pay attention to how many gallons it takes to fill up the tank. This is usually shown at the pump.Record the mileage again, just like before. We will call this Mileage B.Subtract Mileage A from Mileage B. This will give you the number of miles you drove since your last fill-up.Divide your by the number of gallons it took to fill up your tank. This will give you your car's MPG.

It is not rocket science of dimensional analysis, just common sense.

What I would do is fill the gas tank all the way up. Note the cost of the fuel and the amount of gallons it took to fill it. Clear your trip meter so that it is on zero. then run the vehicle for a day or two (depending on how far you drive each day) then refill the tank , note the mileage that you had travelled and divide the mileage that you had gone into the number of gallons it took to fill the vehicle the second time. You now have a estimate of the miles per gallon. Just keep track of the miles you have driven after that.
