I drive a 2007 Pontiac G5 that has a pretty decent Air Conditioner, however, I tend to only use it either when the weather tempature reaches above 90 degrees or I have passengers in the car with me. The reason I hesitate to use the Air Conditioner is that I tend to believe that its use drasticly reduces the fuel economy of the engine and therefore, wastes gas. My friends and family on the other hand believe that the Air conditioners in cars today are much more effecent than those in previous cars and that the drop in fuel economy is very small and therfore, the comfort of the air conditioning is worth lossing a little fuel economy.
Please help settle the argument once and for all. Thanks.
