Seems we've been focused on fuel economy for decades. And that's a good thing. The question then becomes how to get better gas mileage. Here are some tips to keep in mind. Tire pressure must be checked once a month. Most of us check it once a year and only if we see a bulging sidewall. Tire pressure must be maintained for fuel economy, and also for your safety.
The latest thing is to inflate tires with nitrogen, which runs cooler and maintains pressure better than air. Checking tire pressure periodically when filling up is a good habit to develop.
Drive with a light throttle, and do your best to stay in overdrive or final drive once you get rolling. Other fuel economy driving tips include aiming for the smoothest pavement, which requires less power. Consolidate errands and take the UPS approach to planning each journey to the letter. Are you a left foot braker? Left foot brakers tend to ride the brake pedal while accelerating.
Maintain a steady throttle and make finite adjustments to power. For optimum efficiency, you want ignition timing just shy of spark knock, where you achieve peak power and efficiency.
And if you live in the dusty and dry Southwest, air filters should be inspected frequently monthly , when you check tire pressure.
Sensors include coolant temperature, intake air temperature, mass-air flow, throttle position, oxygen O2 , crank trigger, cam triggers, exhaust gas recirculation EGR , manifold air pressure, evaporative emissions canister purge, and automatic transmission. Each of these sensors provides input the electronic engine control needs to provide proper engine function.
Every , miles have all electronic engine control sensors checked and, if necessary, replaced for optimum performance and fuel economy. It is true fuel injectors can live indefinitely. Even the most neglected fuel injectors still perform valiantly because fuel injectors are largely self-cleaning.
They rotate as they open and close, which cleans the needle and seat. And unless your automaker suggests injector cleaning, forget it. If you feel like you must replace fuel injectors, do it every , miles and sleep peacefully. Install overdrive If you own an older collectible car, especially one of the classic muscle cars, and desire better fuel economy for extended cruising, consider installing overdrive.
There are complete turnkey manual five-and six-speed overdrive packages from Modern Driveline where you can do it all in one stop. Gear Vendors has bolt-on overdrive packages for a variety of vintage manual and automatic transmissions. These are stealthy overdrive systems you can install in a classic car and no one will know they are there but you.
When in overdrive, your car will sip fuel rather than gulp it. But did you know a custom dyno tune can also improve fuel economy? This article is intended for educational purposes only, and should not be taken as legal advice or literal interpretation of any specific traffic law.
Before You Travel Try to purchase your gas at the coolest time of day. Gas is densest at these times, so you'll get more out of the volume. When starting your car, you don't need to run it for more than 45 seconds.
After that, you are just wasting fuel. Make sure tires are pressurized to the maximum limit provided by the manufacturer. Traveling on deep tire tread dramatically reduces fuel efficiency. Remove unnecessary devices such as snow tires if they aren't needed.
Remove excess weight from car that can also reduce gas mileage. When purchasing a new vehicle, look at the vehicle's rated fuel efficiency.

Check the pressure every month and adjust accordingly. Tires with overly worn tread? Replace them to increase gas mileage and to keep you driving safely. Reduce drag by removing excess weight.
