Tire pressure also goes down with temperature drop. I think it is 1 psi drop per each 10 degree F drop. I can see a 40 degree drop could easily be seen on the gas gauge if the tires were not topped off.

Around here they put 10% ethanol in the gas from November until the end of March, they say it is for emission reasons. BS. I would normally see a 8 - 10% drop in mileage when I was driving a gas vehicle. I went from 320 mile tanks to about 287 mile tanks before the fuel light would come on. How is burning an extra 1.5 gallons of fuel good for the environment?
