Improve fuel economy through regular maintenance (tires, filters, oil), steady driving (moderate speeds, cruise control, less idling), and reducing weight and aerodynamic drag (remove rooftop carriers, clear out heavy cargo). Do not use unapproved additives like acetone. Consider hybrids or EVs if you want bigger, long-term reductions in gasoline use.
Why fuel economy still matters
Rising fuel prices and cleaner-vehicle standards make using less gasoline both practical and responsible. Small, consistent actions - maintenance, driving habits, and equipment choices - add up to real savings.Maintenance that helps
- Keep tires inflated to the vehicle manufacturer's recommended pressure and check alignment regularly. Proper tire care reduces rolling resistance and can improve fuel economy by a few percent.
- Replace a severely clogged engine air filter and follow the manufacturer's tune-up schedule. Modern fuel-injected engines need fewer tune-ups than older cars, but worn spark plugs or ignored service items can harm efficiency.
- Use the right grade of motor oil and change it at the intervals recommended in your owner's manual. Some modern engines benefit from lower-viscosity oils specified by the manufacturer.
Driving habits that save fuel
- Drive smoothly. Accelerating gently, anticipating stops, and avoiding hard braking reduce wasted fuel and wear on brakes.
- Keep highway speeds moderate. Fuel economy declines quickly as speed and aerodynamic drag increase above roughly 50-60 mph. Using cruise control on steady highway stretches helps maintain an efficient speed.
- Minimize idling. When safe and practical, turn the engine off rather than idle for long periods. Many newer cars include automatic start-stop systems that reduce idling fuel use.
Reduce weight and drag
- Remove unnecessary cargo. Extra weight reduces fuel economy; for many passenger cars, every 100 pounds of added weight can measurably cut efficiency.
- Avoid rooftop carriers when not needed. Roof racks and cargo boxes increase aerodynamic drag and lower highway fuel economy.
Air conditioning and windows
- At low speeds, opening windows has little effect; at highway speeds, open windows increase drag. Use the air conditioner judiciously and rely on the vehicle's recirculation setting to improve efficiency when cooling is needed.
Additives and "hacks" to skip
- Do not use household chemicals such as acetone or unapproved octane boosters in your fuel. Manufacturers and experts recommend only fuel additives approved for your vehicle. Unverified additives can harm engine components and void warranties.
When to consider different powertrains
- Hybrids, plug-in hybrids, and electric vehicles offer substantially better fuel economy or eliminate gasoline use for many drivers. If reducing fuel consumption is a long-term priority, evaluate these options alongside fuel-saving habits.
Bottom line
A combination of routine maintenance, smarter driving, and reducing unnecessary weight and drag delivers the most reliable fuel-economy gains. Avoid unproven fuel additives and follow your vehicle maker's guidance for optimal results.FAQs about Increase Gas Mileage
