6 Ways to Maximize Your Car’s Fuel Efficiency – Easy Tips for Saving Money at the Pump

With gas prices constantly fluctuating, improving your car’s fuel efficiency isn’t just smart—it’s essential. At Southport Automotive Service, we want to share some commonly recommended suggestions that may help boost fuel efficiency and reduce trips to the pump.

1. Keep Your Tires Properly Inflated

Many experts suggest that under-inflated tires could reduce gas mileage by up to 3%. When your tires lack air, your car must work harder to move, which might require more fuel. Checking your tire pressure regularly and keeping it at the recommended level (usually found in your owner’s manual or on the driver’s side door jamb) could help reduce rolling resistance. This simple step might improve your fuel efficiency and extend the life of your tires.

2. Stay on Top of Routine Maintenance

Routine automotive maintenance, like oil changes, air filter replacements, and spark plug checks, is often recommended for better fuel economy. A clean air filter allows your engine to breathe more easily, and fresh oil keeps engine parts lubricated and running smoothly. While results vary by vehicle, keeping up with scheduled automotive maintenance could help your engine run more efficiently and reduce fuel consumption.

3. Lighten Your Load

Carrying unnecessary weight in your vehicle can force the engine to work harder, which might lead to using more fuel. Removing heavy items you don’t need, whether from the trunk or back seat, can reduce this burden. Additionally, if you have roof racks or carriers that aren’t in use, taking them off could decrease wind resistance, helping your car run more efficiently on the road.

4. Drive Smoothly

How you drive plays a significant role in fuel efficiency. Rapid acceleration and hard braking are often linked to increased fuel consumption—studies suggest they could reduce fuel economy by up to 30% on highways and 40% in city traffic. Maintaining steady speeds, anticipating stops, and using cruise control on highways when appropriate may promote better gas mileage. These driving habits can also contribute to safer road behavior.

5. Limit Idling

Idling your car wastes fuel and increases emissions unnecessarily. If you anticipate being stopped for over a minute, turning off your engine and restarting when you’re ready to move might be more fuel-efficient. Modern vehicles are designed to use minimal fuel during startup so that this practice could save gas over time.

6. Use the Right Motor Oil

Using the manufacturer’s recommended motor oil for your car is often suggested to improve fuel efficiency by 1–2%. Some motor oils labeled “Energy Conserving” contain additives that may reduce engine friction, allowing your engine to run more smoothly and efficiently. Always check your owner’s manual for the correct oil type and grade for your vehicle.
