Saving gas isn't just for the car. As spring nears, it's a good time to remember that simple lawn mower maintenance can save gas, and cut pollution by as much as 50%. That's a significant cut, considering a push mower can produce as much pollution per hour as 11 cars.

Here are the four steps you can take, short of replacing your old gas mower with an electric or self-propelled model, to help improve fuel efficiency and cut down on one of the largest sources of residential pollution.

1. Change the oil: Just as in a car, dirty oil cuts down on engine performance.

2. Check the air filter: Consult your owners manual for specifics, but regularly clean your air filter, and consider replacing it at least every two years.

3. Swap the spark plugs: Old spark plugs should be replaced.

4. Sharpen your blade: A sharp blade not only cuts on the first pass, but will leave grass in a healthier state for regrowth.
