CarChooser How to Improve Your Car's Fuel Efficiency
Tips and tricks to maximize your car's fuel economy and save money at the pump.
With rising fuel prices, maximizing your car's fuel economy is more important than ever. By following a few simple tips and tricks, you can save money at the pump and reduce your environmental impact.
Understanding Fuel Efficiency
Fuel efficiency refers to how far a vehicle can travel on a specific amount of fuel. It's typically measured in miles per gallon (MPG) or liters per 100 kilometers (L/100 km). Improving your car's fuel efficiency means getting more mileage out of each tank of gas, which can lead to significant savings over time.
Regular Maintenance
Keep Your Engine Tuned
A well-maintained engine runs more efficiently. Regular tune-ups can improve your car's fuel economy by an average of 4%. Ensure that your spark plugs, air filters, and fuel injectors are in good condition.
Check Tire Pressure
Under-inflated tires can lower gas mileage by about 0.2% for every 1 psi drop in the average pressure of all tires. Check your tire pressure monthly and keep them inflated to the manufacturer's recommended levels.
Use the Right Motor Oil
Using the manufacturer's recommended grade of motor oil can improve your gas mileage by 1% to 2%. Look for motor oil that says "Energy Conserving" on the label to ensure it contains friction-reducing additives.
Driving Habits
Avoid Aggressive Driving
Speeding, rapid acceleration, and hard braking can lower your gas mileage by 15% to 30% at highway speeds and 10% to 40% in stop-and-go traffic. Drive sensibly to improve fuel efficiency.
Observe Speed Limits
Gas mileage usually decreases rapidly at speeds above 50 mph. Each 5 mph you drive over 50 mph is like paying an additional $0.20 per gallon for gas. Use cruise control on the highway to maintain a constant speed.
Reduce Idling
Idling can use a quarter to a half-gallon of fuel per hour, depending on engine size and air conditioner use. Turn off your engine when parked to save fuel.
Vehicle Load and Aerodynamics
Lighten Your Load
Carrying excess weight in your vehicle can reduce fuel economy. An extra 100 pounds in your vehicle could reduce your MPG by about 1%. Remove unnecessary items from your car to improve efficiency.
Reduce Drag
Car roof racks and carriers can increase aerodynamic drag and lower fuel economy. Remove them when not in use to improve your car's aerodynamics.
Fuel Choices and Alternatives
Choose the Right Fuel
Use the octane level recommended by your car's manufacturer. Using a higher octane fuel than necessary does not improve fuel efficiency and is a waste of money.
Consider Alternative Fuels
Hybrid and electric vehicles offer significant fuel savings. If you're in the market for a new car, consider these options for better fuel economy and reduced emissions.
