Fuel Economy...
Something I was thinking about on my way in to work this morning...
My wife filled up the tank yesterday in our Explorer. That thing has a larger gas tank than I thought... Anyhow, does having more gas in your tank cause worse fuel economy? For example, my Explorer apparently has an 18 gallon tank. When that's full, that's an additional 120 pounds (or so) that I'm now lugging around... Does that make my gas mileage worse?
What my gasoline weight research revealed:
"The typical weight of gasoline at 72 degrees F was around 6.25# per gallon. As it became cooler it became more dense and thus weighed more and above this temperature it was less dense and a gallon weighed less."
