What steps can I take to increase the fuel efficiency of my automobile?

In order to get maxiumium fuel effeciency drivers should take several steps. First, ensure that all tires are inflated to the manufactuer reccomended levels. Low tire pressure can cause a loss of fuel economy. Also, drivers should ensure their intake is clean, as a dusty/dirty intake can limit the flow of air into the engine, causing a loss of fuel economy. Finally, owners should go to have their car inspected at a dealership at least once a year to ensure that everything is running properly and there are no issues with the engines, which can become damaged over time which can result in bad fuel economy. Also, cleaning out the inside of the car is a great option, as any unnecessary weight in the car will decrease fuel economy as well, the lighter the car, the greater the fuel efficiency. Accelerating slower is also helpful, the faster you accelerate, the worse milage you are getting.
