How To Extend Gas Mileage

In these times of uncertain finances and economic downturn, you will want to be as practical as possible to save as much money as you can. You will want to learn how to start saving up and spending wisely: lowering your expenditures on luxuries and non-necessities is first and foremost, and you will eventually have to learn how to adjust your spending for your utilities and other necessities. One of the necessities that you will have to learn how to curb is your expenditures on gasoline. While having a car is an absolute necessity nowadays, you will have to learn how to drive wisely in order not to waste your money on fuel-inefficient cars and driving techniques. Here are some things you may want to keep in mind when attempting to extend your gas mileage.

  • Make sure you make fuel efficient choices. The larger the engine of a car, the lower its gas mileage. If you are going to be doing mainly city driving, you may want to go for smaller cars with smaller, and more fuel-efficient engines. Certain carmakers pride themselves on the fuel efficiency of their cars – the BMW Diesel 3 series claims to go up to 21 km on a single liter. Manual shift cars are also more efficient that automatic transmission vehicles.
  • Keep your car clean. Removing any excess junk in the trunk removes the dead weight that makes your car heavier and less fuel efficient. Try to clean your car daily, if not at least once weekly.
  • You should choose the right kind of gas for your car. Each car runs on a certain optimum gasoline (which is defined by octane rating). Make sure you refuel with the gas recommended by your vehicle’s manufacturer. Choosing the wrong kind of gas for your car will lower its efficiency. If you want to be more fuel-efficient, avoid “green” gasoline-ethanol mixtures. These provide less energy to your car, making it fuel-inefficient, and can possibly ruin your engine.
  • Increasing your tire pressure also improves your mileage. Studies have shown that an increase of 2 psi increases your mpg by at least 1%. If you lower the viscosity of your oil from 10W-40 to 5W-30, the decreased resistance will actually improve your gas mileage. Synthetic oils (or at least, conventional oil + additives) are also a way to improve your mileage.
  • The most fuel-efficient speed for your car is around 60 kph. Try to keep at this level, or below this speed. If you go above this limit, the car burns more gas in a fuel-inefficient manner. Leaving your car idling also wastes gas. If you anticipate being stuck in traffic jams for extended periods of time, you can opt to switch off your engine. Keeping your car in cruise control also can save up on gas, as well as avoiding constant switching of gears.
  • If you want to improve your car’s mileage through an overhaul, the best parts to replace include: spark plugs, oil, distributor, PCV valve, air cleaner, oxygen sensor and the preheater hose. Defects in any of these parts drastically reduce fuel efficiency. You can also choose to install radial tires, a vacuum gauge, an mpg gauge and a clean air filter to help improving your mileage.

Do not be fooled by products that claim to improve gas mileage. Tests by credible and authenticated bodies have shown that these products either improve the mileage only marginally or even reduce it. You could also put your car at risk with these products.
