On the other hand, on Cartalk, a woman called in wondering why her gas mileage went down when she needed an oil change, and went back up when she changed the oil. The answer, of course, is that the garage automatically checked her tire pressure when they changed the oil. Her tires were probably pretty low.

"You PAY for air?!" Around here gas stations have coin operated air, 50 or 75 cents, and they usually don't work well. I bought a cheap compressor at Lowes recently. Also, since I have asthma, I would gladly pay for CLEAN AIR. So, I'd like to thank all you hybrid owners for helping me breath!
