If the fuel tank is less than full, you compensate by adding a corresponding weight where the fuel tank is located(around 6 pounds of gasoline per gallon.
From what I have seen, some premium/performance makes, like BMW, suggest weights(sand bags) on driver, passenger, trunk aside from having the fuel tank full. Hunter & Hofmann do follow them. This is to simulate their independent suspension's angles not just when the vehicle is loaded but also when it's driven at high speeds.
