Fuel efficiency is the ability of the vehicle to withdraw energy from the fuel. By modifying certain driving habits and with proper vehicle maintenance, fuel efficiency can be improved. Fuel efficient practices are not only healthier for the pocket but also benefit the environment. Here are some tips that can help you increase gas mileage for better fuel efficiency. Driving Practices that Benefit Fuel Efficiency Avoid hard brakes and rapid acceleration- pressing on the brake or accelerator constantly can wear off the pads and rotors. Do not "warm-up" the engine- cold engine operations consume more fuel. The engine reaches the optimal temperature faster if you start and drive the vehicle without "warming up." Utilize the cruise control- it reduces fuel consumption by maintaining a constant speed. Avoid idling or stop the engine when doing so- it's best to avoid idling because the fuel consumed during idling is more than that required to restart an already warm engine. Drive slowly- reducing speed is a fuel-efficient choice because an accelerating engine utilizes more fuel. Roll up the windows when driving on a highway- closed windows are a better option to improve gas mileage because opening windows increases resistance by trapping air, and the engine utilizes more fuel to work against this resistance. Run multiple errands in a single trip- planning the trip can save unnecessary driving and fuel consumption. Well-Maintained Vehicle Improves Fuel Efficiency Properly inflated and well-aligned tires- smooth driving with minimum resistance enhances fuel efficiency. Use synthetic, low-viscosity motor oil- thinner oils and fluids are fuel-efficient as they decrease resistance. Buy fuel from the top tier brands- quality fuel prevents deposits in the engine system and aids in improving fuel economy. Switch off the air conditioning- opening windows is a better choice to avoid fuel consumption by air conditioning systems. Clean the air filter if you have an older carbureted car- dirty filters make the engine work harder to draw air and decrease fuel efficiency. Do not carry stuff in the truck or roof- excess weight in the vehicle increases the aerodynamic drag. Removing heavy stuff from the car increases fuel economy. Bottomline Improving our driving practices and complying with the maintenance schedule of our vehicle can lower the fuel expenditure and also minimize the release of harmful gases into the environment.
