5 'completely wrong' ideas about saving gas for cars

Besides useful ways to save fuel for cars, there are also some wrong views that are not effective when applied.

High quality gasoline, more economical

Using high-quality fuel does not always result in fuel economy. For cars with small engines and used only for daily commuting, using high-quality fuel, although it will improve the power consumption of the engine and avoid pre-ignition, does not help save fuel.

High quality fuel is only suitable for sports cars because the engine capacity of these cars is large, which has higher fuel requirements.

Open the door, turn off the air conditioner

Many people still believe that opening the windows and turning off the air conditioning while the car is running will significantly save fuel. However, the truth is that doing so will cause outside air to flow into the car and affect the car's aerodynamics without improving performance much.

Filter dirty air

Many people believe that dirty air filters will waste fuel. However, this is no longer entirely true. Today's cars no longer use carburetors but instead use flow sensors and fuel injection to optimize engine performance. For older cars, clogged air filters only slow down the intake process and do not significantly affect fuel consumption.

Fill up when it's cool

In fact, refueling in cool weather conditions does not affect fuel economy much. Because fuel tanks at gas stations are always designed to be deep underground, ensuring that temperature changes during the day do not affect fuel.

Since the temperature difference is only about 2°C, the expansion is not much, if you buy 1 liter, it will only expand by a thousandth. This will not make any sense to save gas.

Fuel efficient tires

Low rolling resistance tires are tires that improve fuel efficiency by minimizing the energy wasted as the tire rolls down the road. While this is an important factor in fuel economy, studies have shown that the two types of tires are almost equally fuel efficient.
