Quick Wins for Better MPG
Use this list to start saving fuel today:
- Smooth acceleration and braking: Jackrabbit starts waste 20-30% more gas. Aim for steady speeds.
- Keep tires inflated right: Check to 32-35 PSI weekly. Underinflated tires drop mileage by 3% per PSI low.
- Lighten your load: Remove roof racks and extra weight. Every 100 pounds cuts 1-2% MPG.
- Use cruise control on highways: Holds steady speed to save 5-10% on long trips.
According to AAA's 2025 Driving Costs study, fuel costs hit $1,950 a year for typical cars at 15,000 miles. "Proper tire pressure and smooth driving save drivers up to 15% on fuel," says the AAA Research Team, based on analysis of 1.2 million vehicle records (Source: AAA Your Driving Costs, 2025).
Maintenance Checks That Pay Off
Stay on top of these to gain 5-10% better mileage:
| Check | How Often | MPG Boost |
|---|---|---|
| Air filter | Every 15,000-30,000 miles | 5-10% |
| Oil change | Every 5,000-7,500 miles | 1-4% |
| Spark plugs | Every 30,000 miles | 3-5% |
| Fuel system clean | Yearly | 4-8% |
Fresh oil and clean filters keep engines running at peak. Dirty parts force harder work and burn more gas. In zip code 80239, gas runs about $3.25 per gallon. That means a 10% mileage boost saves $195 yearly.

Shift how you drive for steady gains:
- Avoid idling over 10 seconds. Restarting uses less fuel.
