David,

The readings are based on ambient temp and humidity.

Google R134a pressure chart, find one that includes humidity, because the higher the humidity the higher the low and high side pressures will be for a given ambient temp. Here is an example of one:

I have the same situation Gil Does. The local stations are now running about $.15 cheaper than the truck stops. But no matter which way I approach or leave the house going to the cheap local one costs me 16 miles. At 6MPG it is almost 3 gallons so at todays prices I need to save enough to compensate for the almost $11 in fuel I burn.

At $.15 cent savings I need to pump at least 73 gallons. But even if I pump 125 gallons and save the $7.80 I can’t use my credit card because at those stations they let you pump about $85 to $100 dollars worth and the pump shuts off. So instead you have to walk in and wait for everyone buying cigarettes, lottery tickets or milk, leave a pile of cash and then try to pump all that fuel through a nozzle the size of a #2 pencil.

Truck stops equal stop, swipe, pump, go. and they are in the path of my travels and the pump will actually fill my tank in a few minutes.
