Gah, damn my insatiable thirst for knowledge. After doing some research and make some of my own conclusions.
At 6 feet down the temperature of the ground is relatively stable year round. Depending on where you live it can be anywhere from 45F to 70F, but usually doesn't delta more than 5-10%.
What does this mean. In short it means pumping gas early because of it being cooler is absolute BS. I know how to work out the math to show much the volume will change over a 10 degree delta, and if you want that I can get it.
