At what temperature should the car's air conditioner be set to consume the least amount of fuel?

The car’s air conditioning can almost be considered an active safety system, as it allows you to travel in more comfortable conditions, thus improving driving, especially in summer when temperatures start to rise. During the scorching days, which are almost unbearable, exhaustion and fatigue await the drivers and make the journey very hard. Benefiting from air conditioning in this period is a real luxury. It is still necessary to use it wisely, because it is very greedy on fuel. And as everyone knows, now is definitely not the time to splurge. The price of gasoline and diesel continues to rise. How to effectively adjust the air conditioning to avoid excessive fuel consumption?

With thermometers showing temperatures above 30°C, automotive air conditioning is your most valuable ally right now. But it must be used with intelligence and parsimony: although it saves the lives of the driver and passengers, this system greatly affects the car’s energy consumption. In fact, it is not uncommon to notice a significant drop in power while driving, with a consequent slowdown of the vehicle, a sign that the use of air conditioning is compromising engine performance.

What is the optimal temperature of the car’s air conditioning to consume less fuel?

We all know that the use of air conditioning increases the fuel consumption of the car. This is not good news, given current fuel prices. It should be noted that this consumption is influenced by the difference between the outside temperature and that of the passenger compartment.

Specifically, according to the Daily Drive, specialized in the automotive industry, if you try to reach a temperature difference between the outside and inside environment of 5 degrees, fuel consumption will logically be much lower than a possible difference of 15 degrees. Therefore, specialists recommend achieving a difference of no more than 6 to 8 degrees between the interior and exterior. Note that the age of the car and the performance of the air conditioning system must also be taken into account.

As a general rule, when we use air conditioning in the car, the additional fuel consumption will be between 0.5 and 1.5 liters per 100 kilometers. Older cars may have higher consumption. As for the most powerful vehicles, they may even need less than 0.5 liters of fuel per 100 kilometers.

Despite a slight drop, fuel prices have remained high of late, much to the chagrin of motorists who spend their time complaining about this problematic situation. Unfortunately, they don’t have many options and have to make do.

However, according to experts, there are certain methods to significantly reduce fuel consumption. Here are some tips that all drivers should follow:

– Do not drive at high speed

Driving at a moderate speed will save you a few liters of fuel. For example, reducing highway speed from 130 km/h to 110 km/h saves one liter of fuel every 100 kilometres. The difference in speed being small, the loss of time is really insignificant. Not to mention, you’ll avoid the risk of fines down the road.

– Do not force the engine in the first kilometers

I’m sure many drivers already know this: a car with a cold engine consumes more fuel than a car with a hot engine. Therefore, do not force the engine in the first kilometers, at least until it warms up. Therefore, it is preferable to drive at low speed for the first few kilometres. Warning: letting the car idle for a few minutes is not a good idea. And for good reason, the engine won’t heat up as quickly with low-speed driving for a few miles.

– Try to maintain a constant speed

Certainly, in some situations, it’s really hard to do, especially when there’s traffic. However, you will consume more fuel if you accelerate hard and brake soon after. And so right away. So try to maintain a constant speed, whenever possible of course.

– Fuel consumption also depends on engine speed

Generally, the ideal speed, in terms of rpm, is around 3,000 rpm for gasoline engines and 2,400 rpm for diesel engines. However, it is best to check these figures, as they differ depending on the engine displacement.
