Proper air pressure saves gas
My mechanic told me that I should be checking tire pressure weekly and also whenever it was a particularly hot or cold day. Apparently tire pressure can fluctuate quite a bit with temperature changes and when the pressure is not within the optimal range, you use more gas. These days we need to save every bit that we can so I thought I'd pass this one in case someone else didn't know.

The car person you spoke
The car person you spoke with is correct and its one of the first things they told us years ago in driving school. I think many people don't realize how something unbalanced can really effect things until its broken down and noted more than once.
I check my tire pressure
I check my tire pressure every time I put in gas as well as anytime I feel the temperature is so hot or cold I need to use the AC or heat. I bought a nice digital pressure reader to make it quick and easy compared to the manual ones which never seem to work well.
I know that I SHOULD do
I know that I SHOULD do this, but I next to never do. How much of a difference does it make? I always seem to be filling up on the run, and I wouldn't tend to think about it any other time.
