Things to do > Car Care Tips
Keep your car well-maintained - get regular tune-ups

The engine will pollute less, run smoothly and save you money.

Change the fuel filter and air filter at least once a year, or every 12,000 miles

A dirty air filter has restricted air flow causing the engine to operate less efficiently.

Keep tires properly inflated and aligned

This will reduce emissions and save fuel.

Fill up your gas tank after sunset

This will keep evaporative emissions from reacting with sunlight to form ozone pollution (smog).

Don't top off your tank when you refuel

It may cause spillage, which evaporates and contributes to smog.
