Whether a fuel consumption of 20L is normal for a new car depends on the model. For some high-displacement models, a consumption of 20L can be considered normal. However, if ordinary family cars show such fuel consumption, it is not quite normal. Actual fuel consumption is related to many factors, such as season, temperature, road conditions, driving habits, and vehicle load. The following are related introductions to car fuel consumption: Constant-speed fuel consumption: refers to the fuel economy indicator when the car is driving at a constant speed on a good road surface. Since constant-speed driving is a basic operating condition for cars on highways, and this type of fuel consumption is easy to measure, it is widely adopted. Road cycle fuel consumption: the fuel economy indicator measured when the car drives in repeated cycles according to specified speed and time regulations on the road, also known as multi-condition road cycle fuel consumption. The speed and time regulations specify each cycle to include various driving conditions, and also specify the shifting time, braking and stopping time, as well as the values of driving speed, acceleration, and braking deceleration for each cycle. Therefore, the fuel economy measured by this method is closer to the actual driving conditions of the car.

My newly bought SUV also gave me a shock at first, showing over 19L/100km fuel consumption. It's normal for the engine to have higher friction resistance during the first few hundred kilometers of the break-in period, especially when frequently stuck in city traffic with AC on - the fuel consumption will definitely spike. Also, watch your driving habits - avoid aggressive acceleration and hard braking with a new car, this alone can reduce the gauge reading by 2-3L. My advice is to first drive 1000km steadily while recording actual fuel consumption at each refill. If it remains this high after break-in, you should really visit the dealership to check sensors or the fuel system - don't be like my neighbor who drove for half a year before discovering a clogged charcoal canister.

Hey bro, your 20L fuel consumption is just like my old off-roader! The factory oil viscosity is set high for new cars, so the first 100km doesn't count at all. Pay attention to these details: Are you using sport mode? Is tire pressure below 2.0? Last time my low tire pressure increased fuel consumption by 15%. Turn on the start-stop system, don't blast the AC too hard, and remember to tighten the fuel cap. Take it on the highway this weekend and you'll see - my new car gets just 7.8L/100km on highways but still 18L in city driving. Don't jump to conclusions yet, wait until you've burned through two full tanks. Nowadays many cars show higher fuel consumption readings than actual.

Just helped my cousin with this issue last week. A new car consuming 20 liters per 100km sounds alarming, but break-in period figures tend to be higher. Focus on three key areas: check the trip computer's average speed - anything below 20km/h will definitely increase fuel consumption; verify if the start-stop system on the dashboard is functioning properly; and inspect the energy recovery system activation status. Last time we found she kept the AC at 22°C with max fan speed year-round and had a whole case of mineral water in the trunk. For the first month with a new car, remove all unnecessary weight - the engine oil will be replaced with thinner viscosity at the first service. If abnormal consumption persists, have the dealership check the oxygen sensor data stream - there might be assembly residue causing blockage.
