How can you make your car last 500,000 miles? Irv Gordon, owner of the world's highest-mileage car, a 1966 Volvo with 1,753,000 miles:

1. Change the oil every 3,000 miles.
2. Check the tire pressure weekly.
3. Switch to 15W-40 oil in the winter.
4. Inspect the belts and hoses for cracks every single time you buy gas.
5. Keep it clean. If you take pride in your car, you're going to do a better job of keeping it up mechanically.
6. Powerwash the undercarriage to clean off the road salt in the winter. That stuff will corrode the body if it stays on too long.
7. Degrease the engine once a year.
