Temperature and Density: Warmer fuel (day) expands and is less dense, while cooler fuel (night) is denser. Volume vs. Energy: A given volume of cooler, denser fuel contains slightly more usable energy than the same volume of warmer, less dense fuel. Minimal Effect: For the average driver, the temperature difference bet
