Misconceptions about saving gas for cars

In addition to smooth operation, users are also interested in the car's fuel economy. Notably, some concepts that were once thought to help save fuel are actually ineffective.

Fill up your tank in the morning and your car will go further.

Many people believe that gasoline and oil will expand under the influence of environmental temperature. Therefore, pouring in the morning when the weather is still cool will put more gasoline and oil in the tank. Thanks to that, the car can travel a longer distance.

But in reality, at gas stations, fuel is stored in tanks located underground, and the ambient temperature does not affect the expansion much. Therefore, with the vehicle's fuel tank capacity, filling the tank at any time of the day does not make a difference.

High quality gasoline will save more money

Using high-quality fuel does not always result in fuel economy. For cars with small engines and daily driving, using high-quality fuel improves engine lag but does not have the fuel economy effect that many people think.

High quality fuel is suitable for sports cars because of large engine capacity and higher fuel requirements.

Manual transmission cars are more fuel efficient than automatic transmission cars.

Many people believe that using a manual transmission car will save more fuel than an automatic transmission car. However, this view is no longer correct. Modern technology today helps automatic transmission cars have the same fuel consumption as manual transmission cars of the same type, or even save more.

Starting the car takes more time than idling.

Many drivers believe that leaving the engine running when stopping ensures that the systems are always running and saves fuel compared to turning the engine off and restarting it. In fact, depending on the engine capacity, the car will consume about 1 - 2 liters of gasoline per hour when operating in an idle state.

Furthermore, most current car models are integrated with the new electronic fuel injection system, which uses very little fuel each time the car starts compared to idling.

Therefore, if you stop for a long time, you should turn off the engine. If you only stop at a red light or are not in traffic for long, it is not necessary to turn off the engine.

Changing the air filter helps save gas

This is an outdated concept because today's cars no longer use carburetors, but instead use flow sensors and fuel injection to optimize engine performance.

So, replacing a dirty air filter will not improve fuel efficiency. However, replacing the air filter can improve engine performance.
