# How Can I Improve Gas Mileage?

Check tire pressure every month. This simple step boosts fuel economy by up to 3% in most vehicles. Underinflated tires increase rolling resistance and hurt MPG.

## Key Maintenance Steps
Follow these steps to keep your car running efficiently:
- **Inflate tires correctly**: Aim for the pressure listed on the door sticker. Check when cold. Gain 3% MPG.
- **Change air filters regularly**: Clogged filters cut airflow and waste fuel. Replace every 15,000 to 30,000 miles for better burn.
- **Use the right motor oil**: Stick to the recommended grade. This cuts friction and improves mileage by 1-2%. Look for "Energy Conserving" on the label.
- **Tune the engine**: Fix spark plugs and ignition. A tuned engine saves 4% on average.

| Maintenance Tip | MPG Gain | How Often |
|---|---|---|
| Tire pressure | Up to 3% | Monthly |
| Right oil | 1-2% | Per schedule |
| Air filter | Varies | 15k-30k miles |
| Tune-up | 4% average | Yearly |

## Smart Driving Habits
Change how you drive for big wins. Aggressive moves lower MPG by 33% on highways.

1. Accelerate gently. Take 5 seconds to reach 20 mph. This cuts fuel use.
2. Maintain steady speed. Use cruise control on flats. Save 7-14% by slowing 5-10 mph.
3. Coast to stops. Avoid hard brakes. Keep momentum.
4. Turn off the engine when idling. It wastes a quarter gallon per hour. Restarting uses less fuel.

"Reducing speed by 5-10 mph boosts fuel economy 7-14%," says AAA.

## Cut Drag and Weight
Lighten your load. Every 100 pounds drops MPG by 1%.
- Remove junk from trunk.
- Skip roof racks when empty. They add drag.

Combine trips. One errand run beats many short ones. This skips extra warm-ups.

According to the Department of Energy, these habits save up to 25% fuel. Exxon notes proper tires alone add 3%.
