Why Are Gas Prices So High?

Whats the best way to add gas mileage in the most affective way for a 2006 Chevy Malibu?

it only has 30,000 miles and the gas mileage has been reduced drasticly and nothing has chanced on the car.

1. Maybe it is time for a tune-up? Also, with the cost of gas increasing, if you usually put say $30.00, it will run out a lot faster, because nowadays you get less for the money. However I am sure it is because it needs the tune-up :) !
2. change O2 sensors,tune-up(plugs, air & fuel filters, PCV throttle cleaning, engine decarb.) ,tires at proper pressure. I would think that it is still under warrentee, if so, take to dealer and tell them about your mileage drop.
3. How long has the check engine light been on, or barring that, when did your driving habits change? A dramatic drivability (engine) problem or a dramatic change in driving habits (new job perhaps) are the most likely culprits for a drastic change in gas mileage. That or all of your tires are almost flat because like most American's you don't check them once a month like you should and keep them properly inflated.
