I was filling my car earlier today, and noticed a sticker posted on the pump.
This pump dispenses fuel at a volumetric amount measured in standard gallons (231 cubic inches). It does not adjust for temperature, or other factors that may affect the energy content of each gallon.
This got me thinking.
What would be the optimal conditions to fuel your car so that you can get the most energy per gallon? Let's assume we measure this in miles per gallon achieved traveling at 60mph in a standard car that advertises 30mpg. (a Honda Civic, perhaps)
Why would temperature affect the energy of each gallon?
Ps. I am not sure what to tag this. Please edit accordingly
