Why does the last half of a tank of gas never last as long as the first half?
Most car's I've had don't accurately measure the "true" last half. The level sender measures depth only, but the shape of the tank changes. Also I've noticed that if you check the manual for the tank capacity and the amount required for a fill, you can't fit that much.
The Short Answer
Most car's I've had don't accurately measure the "true" last half. The level sender measures depth only, but the shape of the tank changes. Also I've noticed that if you check the manual for the tank capacity and the amount required for a fill, you can't fit that much. Even when the dash computer in my last two cars indicated 0 miles left to go I always seemed to have 1.5 to 2 gallons left based on the amount it too to fill the tank subtracted from the total capacity.
