Some tricks to saving gas.
1. Try not to use the AC.
2. Keep your tires inflated at 32-35 pounds of pressure. Your car has exact specifications on the door to your gas tank or the lid to the gas tank.
3. Keep the car tuned up. Read your manual and it will tell you the frequency of tune ups and oil changes and other necessary maintenance.
4. Try to drive the car at about 2 RPM's. This is more difficult to gauge on an automatic transmission but if you listen to the pitch of the engine you can get an idea. If she is squealing like you are pushing her, you are probably going too fast and using up more gas.
5. Go the speed limit.
6. If you have a manual transmission, let it coast in neutral when you can. Just to be on the safe side, don't go into neutral when you are using an automatic transmission. If you accidentally put the car in reverse you will end up having transmission problems. My husband is an excellent driver and he won't even take that chance. On the other hand, if you are sitting in line at McDonalds, neutral is good.
7. Don't keep your life in the back of your car. Obviously, extra weight is going to make the engine work harder and use up more gas.
Hopefully these things help. People tend to freak out a little when gas prices go up, but even when they are down, save yourself some money and trouble by using these tricks to keep your gas tank filled.
