Here is the official answer from the dealer and wikipedia. I don't like it but you might. Bottom line is just because you have a 13.2 gallon tank does not mean you can put 13.2 gallons of gasoline the tank. The reason is the fuel pump is inside the tank. I think they should change from the 13.2 gallon designation to whatever the to the actual liquid volume. I feel cheated.
Has anyone had the Juke fuel tank capacity measured by a mechanic?
