Master the art of engine braking to save fuel and reduce wear

Engine braking is simple, but it requires familiarity with your vehicle. The process involves lifting your foot off the gas pedal while keeping the gear engaged. The general rule is that the lower the gear, the greater the reduction in the car's speed.

Shifting from fifth to fourth gear helps decrease speed when descending a hill. Moving to third gear will slow you down even more, but you must be cautious not to overdo it and excessively increase engine RPMs, which can lead to an expensive breakdown. Knowing your car is crucial— each gearbox has different gear ratios. The key to success is matching the gear to the speed and road conditions.

In modern cars, when you release the gas, fuel does not enter the cylinders, allowing you to move without using it. Older models with carburetors did not have this feature so that some older drivers may be unaware of this effect.

This technique is also recommended because it reduces brake pad wear. This is especially beneficial in mountainous areas, where descending without engine braking can overheat the braking system.

However, improper use of engine braking can be harmful. Abruptly reducing gears (for example, skipping multiple gears) can excessively strain the clutch, leading to its wear. Such actions can also negatively affect the flywheel, which helps reduce vibrations.

Safety is crucial, particularly with rear-wheel-drive cars. Although modern cars often have an ESP system to help control excessive rear axle movements, caution is necessary. Reducing the gear on a turn with a wet or sandy surface can lead to a skid. Technology is beneficial, but common sense is irreplaceable— the laws of physics are unchangeable.
