Fuel Saving Tips
On hot days with the windows rolled up, your car's interior can quickly reach high temperatures. Roll down all the windows to vent the hot air before starting your air conditioning. The outside air will also feel cooler than the hot interior. Once I've gotten to the edge of the parking lot, the interior is much cooler. Your car will become cooler quicker and your A/C compressor will not have to work as hard (saving you gas). If you are able to leave the windows rolled down a half inch while parked, then your car's interior will not be much hotter than the outside air when you return.
