Effective Tips for Gas Saving

With the recent economic turmoil, it is essential to try as much as possible to save gas. Gas prices have been rising steadily over the years, which necessitate the need to save more. There are several gas mileage tips that can play a fundamental role in reducing the gas amount used. Some of the tips will be highlighted in this article.

Efficient Driving

It is essential to drive efficiently and sensibly. Aggressive driving, including rapid acceleration, speeding and braking, leads to gas waste. Such driving can lead to reduction of gas mileage by up to 33 percent at speeds on the highways and by 5 % at town speeds. Sensible driving is not only safer for the driver, but also to other people. Therefore, you can actually save more by choosing to drive efficiently and sensibly.

Observing Speed Limit and Removing Excess Weight

It is essential to keep in mind that while every car attains its maximal fuel economy at different speeds, speeds above 50 mph rapidly decrease gas mileage. It is therefore safer to observe the speed limit. Another advice is to remove excess weight. Drivers should not keep unnecessary items in their cars, particularly heavy items. The car’s mpg could be reduced by up to 2% by having additional 200 pounds in the car. The basis of the reduction is the extra weight percentage relative to the weight of the vehicle. Smaller vehicles are affected more than the larger cars.

Avoiding Excessive Idling

Twenty-five percent to 50 percent of gallons of fuel per hour can be used when idling. This depends on the air conditioner and engine size. When a vehicle is packed, drivers are advised to turn off their engines. Restarting a car takes only a few second worth of fuel. However, starter wear may be increased by turning excessive on and off turning of a car engine. Therefore, turning that engine off may go a long way is saving on gas in the current harsh economic situation.

Using Cruise Control

The use of cruise control on the highways not only helps in maintaining constant speed, but also in saving gas. Hence, it is worth trying when possible.

Using Overdrive Gears

The engine of a car goes down when overdrive gearing is used. This not only saves gas, but it also minimizes instances of engine wear. This means that one can achieve a double advantage by choosing to use an overdrive gear.

Generally, gas saving tips should be kept in mind, and most importantly practiced during the tough economic times.

Basics of Electric Vehicles

An electric motor plays the role of propelling electric vehicles. This motor is powered by battery packs that are rechargeable. There are a number of advantages associated with electric vehicles over vehicles that have internal combustion engines.

Environmental Friendliness

Electric vehicles emit fewer pollutants, despite the fact that the power plant generating electric power may emit them. No air pollutants are caused by electricity from solar, nuclear or hydro-powered plants.

Energy Efficiency

In electric vehicles, about 59 to 62 percent of electric energy is converted from the electric grid to power. Only about 17 to 21 percent of energy is stored in gasoline to power in conventional gasoline vehicles.

Reduced Energy Dependence

Electricity has often been considered to be a domestic source of energy. This means that driving an electric car will minimize the rate of foreign energy dependence.

Performance Advantage

Electric motors offer smooth and quiet operation. Additionally, the acceleration provided is strong. Such motors would also need less maintenance compared to internal combustion engine-based motors.

However, there are battery-linked challenges that are faced by electric vehicles. Some of these challenges are as follows.

  • Battery Cost

Electric vehicles need large-sized battery packs that are extremely expensive. These battery packs may also need replacement two or more times.

  • Recharge Time

It can take four to eight hours to recharge a battery pack fully. Even 30 minutes may be required to charge up to 80 percent of the battery capacity.

  • Driving Range

For most electric vehicles, 100-200 miles is the average distance that they can go prior to recharging. This is contrary to gasoline-fueled vehicles that can go up to 300 miles prior to refueling.

  • Bulk and Weight

Battery packs have been thought to be extremely heavy. This means that they often take up considerable space in a vehicle.

Despite the mentioned pitfalls, researchers are working towards innovating battery technologies that would increase the driving range and minimize the costs, weight, and recharging time. These factors serve as the key determinants for electric motors’ future.

Hybrid cars are both electric and gasoline-driven. This means that they combine the benefits of both gasoline motors and electric motors. One of the key benefits that a hybrid car derives from its gasoline segment is in terms of mileage. As mentioned, gasoline vehicles can travel further when compared to electric vehicles. Hence, a hybrid car has an advantage of having better mileage. Other key advantages include energy efficiency, high performance, and promoting a cleaner and safer environment. Additionally, hybrid cars have a unique appearance.
