How to Derive Better Gas Mileage

Fossil Fuels that fuel automobiles come from non-renewable sources and contribute to pollution and global warming in a big way. President Obama’s tough auto efficiency standards that aim to improve cars’ mileage by 40 percent are likely to mitigate the energy crisis in a big way.

Regulations apart, there are various methods by which individual drivers can increase gas mileage for the vehicles. Good driving style, adherence to basic car maintenance tips and making optimal use of the car increase fuel economy by as much as twenty percent!

Driving Style

Irrespective of the declared fuel efficiency of your car, your driving style improves gas mileage, or decreases it in a big way. The following are the major fuel economy driving tips:

Aggressive acceleration and braking increase gasoline consumption and decreases fuel economy. A smooth driving style, with constant speed that does not stretch the aerodynamic resistance of the car, combined with smooth and linear acceleration or deceleration improves gas mileage. Maintaining a safe distance between your car and the one ahead allows sufficient reaction time to apply brakes smoothly.

Driving with your foot in the clutch wastes engine power and not only increase gas consumption, but also wears out the clutch faster. Keeping your foot away from the clutch and pressing the clutch only to change gears or apply brakes leads to better gas mileage.

Waiting for an extended period at traffic signals or other places with the engine on is a waste of gasoline. Switching the engine off during such prolonged waiting periods saves fuel and increases fuel economy.

Vehicles with manual transmission, where the driver shifts gear manually are usually more fuel efficient compared to vehicles with automatic transmission, where the vehicles selects the gears automatically. In manual transmission vehicles, it is however pertinent to shift to a higher gear as early as possible without straining the engine. The optimal shift point is between 1500 – 2000 rpm for most vehicles. Remaining in a lower gear at very high speed or in a higher gear at low speeds strains the engine at increase fuel consumption, leading to poor gas mileage.

Car Maintenance

Adherence to basic car maintenance tips contributes to better gas mileage in a big way.

The car gulps fuel voraciously if it is not in the right state of tune. Tuning the car at regular intervals, cleaning air-filters and spark plugs, and changing engine oil at the recommended maintenance intervals contributes to a better gas mileage. Dirty air intake filter and spark plug decrease the amount of air entering the engine, resulting in incomplete combustion and more fuel consumption.

Manufacturer-recommended tire pressures optimize the level of rolling resistance and contribute to an increase in fuel efficiency. Deviance from the optimal tire pressure not only increases rolling resistance leading to more fuel consumption, but also causes uneven wear to the tire. Oversized tires also increase the rolling resistance and rotating mass, and increase fuel consumption.

Optimal Usage

How you use your car has a significant impact on the fuel efficiency.

Taking the car for short trips leads to increased fuel consumption. Car engines have an optimal running temperature when it consumes the least amount of gasoline. Short trips usually results in the car running at a cold temperature for a majority of the distance, leading to poor gas mileage. If walking or cycling is out of your radar, then planning your trip to cover more tasks per trip is a good alternative to frequent short trips.

The greater the weight, greater the work for the engine, and greater the amount of fuel consumed. Unloading unnecessary cargo and baggage to keep the car as light as possible increase fuel economy.

Constant acceleration and deceleration and frequent use of the clutch and brakes lead to increased consumption of gasoline. Avoiding rush hour traffic by traveling either before or after the peak hours ensures a comparatively smooth ride and better gas mileage.

Open windows affect the cars aerodynamic efficiency at high speeds. Keeping the windows rolled up and the air-conditioner on at speeds over sixty miles per hour contributes to aerodynamic efficiency and improved gas mileage.

All these measures, individually and in combination contribute to better fuel efficiency in a big way, and not only provide you considerable savings on gasoline prices, but also reduces pollution and global warming and make the world a better place.
