1. Start by regularly checking your car’s maintenance schedule and make sure all recommended services are up-to-date.
2. Reduce the amount of air pollution you produce.
3. Make sure your tires are properly inflated.
4. Use the most efficient driving techniques, such as accelerating and braking gently.
5. Consider replacing your engine oil and filter every 3,000 miles or 6 months, whichever comes first.
6. Avoid hard acceleration and heavy braking whenever possible.
7. Try to maintain a steady speed when cruising on highways.
8. Check your tire pressure once a month, especially during hot weather.
