You’ve got your number, but what does it actually tell you? Fuel efficiency can vary dramatically based on your vehicle’s type, age, and engine size. Here’s a general guide to help you benchmark your result:

If your MPG seems low, don’t worry! There are many simple things you can do to improve it.

10 Actionable Tips to Improve Your Gas Mileage (And Save Money)

Even a small improvement in your MPG can lead to big savings over time. Here are proven strategies to get more miles out of every gallon:

1. Maintain Proper Tire Inflation: Underinflated tires create more rolling resistance, which can lower your gas mileage by up to 3%. Check your tire pressure monthly.
2. Drive Smoothly: Aggressive driving (rapid acceleration, hard braking) is a major fuel-waster. Accelerate gently and anticipate stops to coast more.
3. Reduce Your Speed: Fuel economy typically peaks around 50 mph (80 km/h) and decreases rapidly at higher speeds. On the highway, driving 65 mph instead of 75 mph can save you up to 15% on fuel.
4. Eliminate Excess Weight: For every 100 lbs (45 kg) of extra weight in your car, your MPG can drop by 1-2%. Remove unnecessary items from your trunk or cabin.
5. Avoid Excessive Idling: An idling car gets 0 MPG. If you’ll be stopped for more than 60 seconds, it’s more fuel-efficient to turn off the engine.
6. Use Cruise Control on Highways: Maintaining a constant speed on flat, open roads helps the engine work most efficiently.
7. Stick to Your Maintenance Schedule: Regular tune-ups, oil changes (using the recommended grade of motor oil), and clean air filters help your engine perform at its peak efficiency.
8. Reduce Aerodynamic Drag: Remove roof racks or cargo boxes when not in use. They can decrease your fuel economy by 5-20%.
9. Plan Your Trips: Combine errands into a single trip. A warm engine is more efficient than a cold one, so several short trips can use more fuel than one longer, multi-stop trip.
10. Use Air Conditioning Wisely: The A/C compressor puts a significant load on the engine. On cooler days or at lower speeds, consider using the fan or opening windows instead.
