Driving with Excess weight is another way to throw money down the drain. If you have tons of junk in your trunk then you need to get rid of it. There's no point of carrying beach chairs if your not going to the beach!
Get a tune up and you can see a world of difference. If its been a while since your car was last serviced, then you could be wasting a ton of gas. If your car isn't in peak shape then it will require more gas to push the car since it is losing power.
