Better fuel efficiency saves money and reduces emissions. Many factors affect gas mileage, and maintenance plays a key role.

**Maintenance tips for better efficiency:**
- Keep tires properly inflated (under-inflation increases drag)
- Replace air filters regularly (a clean filter helps your engine breathe)
- Use the correct oil viscosity (thinner oil reduces friction)
- Keep your engine tuned (worn spark plugs or injectors waste fuel)
- Check wheel alignment (misaligned wheels drag)
- Service your transmission on schedule

**Driving habits also matter:**
- Avoid aggressive acceleration and braking
- Remove excess weight from your vehicle
- Maintain steady speeds on highways
- Use cruise control when appropriate
