I'll be passing by this station after work but it's hot when I pass it. The best time to get gas is when It's cold outside.
Something else I've found is that if drive less than a few miles before filling up, you can get more gas in the tank. This is because there hasn't been as much warm gas returned to the tank throught the return line.
So you are saying get gas while the car is cold???
Yes. I haven't figured out whether or not you get any more mpgs or not but it should help you pack more fuel into the tank. It could help with those temporary price spikes so you can wait until the price comes back down.
Horsepower is how hard you hit the wall, torque is how much of the wall you take with you.
