how to improve your gas mileage.  I often get asked for advice on how to improve your gas mileage.  You’ll be happy to know that it’s really not too hard.  For example, one of the best things you can do that will have your gas mileage improving is to slow down and drive more conservatively.  Once you get out on the interstate, it isn’t a race – drive the speed limit and it will make a difference.  Also, when you’re accelerating, don’t punch it, do so slowly and the same goes for braking.  Try to anticipate when you’ll need to stop and apply the brakes gently (when safety permits – if you need to slam on the brakes for safety reasons, then by all means do so).
