Petrol Usage Car AC: In today’s times, the AC facility in a car is no longer just a luxury item, but has become an essential necessity. Especially in the hot summer sun, driving without AC seems not only difficult, but almost impossible. However, running an AC has a direct impact on your pocket, as it increases petrol consumption. For this very reason, many people use their car AC carefully and thoughtfully.

How much does it cost to run an AC for an hour?

Now, the big question is: If you leave your car’s AC on for an hour straight, how much gasoline does it cost? The answer varies depending on the specific car model. Actually, it totally depends on the engine of the car and its capacity (size). Smaller cars like hatchbacks and sedans usually have lower fuel consumption, as they are fitted with 1.2 to 1.5 liter engines. In contrast, larger SUVs have engines of 2.0 liters or more, resulting in higher petrol consumption.

What is the difference between small and large cars?

As a rough estimate, cars with 1.2 to 1.5 liter engines can typically consume 0.2 to 0.4 liters of petrol to run an AC for an hour. Conversely, in SUVs with 2.0 liter or larger engines, this consumption can increase to 0.5 to 0.7 liters per hour. However, these figures are not definitive; Because various factors like driving style, traffic conditions and weather also play an important role in this.

Follow these methods for better cooling

If you want your car’s AC to keep providing excellent cooling without consuming too much petrol, adopting some simple measures is essential. First and foremost, make sure your car AC is regularly serviced. If the filter is dirty and the amount of ‘refrigerant’ (gas) in the AC is low, the cooling efficiency deteriorates and additional stress is placed on the engine. It is beneficial to have AC checked every 6 to 12 months. Also, avoid running the AC at full speed immediately after starting the vehicle. Instead, open the car windows first, so that the hot air trapped inside the car can escape; And then turn on the AC. This helps in cooling the interior of the car very quickly.

Keep these things in mind while driving

Always keep your car’s AC (air conditioning) on ​​medium setting while driving. Driving it continuously at full speed increases fuel consumption. Try to park your vehicle in the shade or use a ‘sunshade’ to keep the interior of the car (cabin) from getting too hot. Avoid opening windows frequently during travel; Because this causes the cold air in the car to escape and the AC has to work harder. Additionally, use ‘recirculation mode’; This prevents hot outside air from entering the car and helps cool the car faster.

Use it wisely to save money

Although car AC certainly provides a comfortable experience, if not used judiciously, it can put a big dent in your pocket. So, by following the right practices, you can enjoy a cool and comfortable ride at the same time, while also saving on fuel costs.
