I think about airplanes, let's take a 747 for example with full fuel, it may cruise at first at maybe FL350 then as it burns more fuel, it gets lighter and may stair climb to FL390.
It got me thinking I think diesel weighs like 7.5 lbs per gallon so a fully loaded tank has somewher around[16gallons] 120lbs or so. Let's say you burn a good 8 gallons, you have now shed 57 lbs or so. The engine isn't pulling as much weight etc.
How much does this affect performance.
Let's model a 2000 GOLF 5SPD
Without getting complex
80MPH steady with a full tank 16 gallons, vs 80MPH with a half tank 8 gallons
