14 liters means a fuel consumption of 14L per 100 kilometers. Whether this is high is relative. For example, it is considered high for small sedans with an engine displacement of around 1.6-2.0L, but it is normal for large-displacement vehicles, such as large SUVs. Ways to reduce fuel consumption: 1. Correctly adjust tire inflation pressure: Proper tire pressure can reduce rolling resistance and lower fuel consumption. Additionally, slightly higher tire pressure (about +0.2bar above the recommended value) can also save fuel. 2. Use in-car auxiliary electrical equipment moderately: Some electrical devices significantly increase fuel consumption, such as the air conditioning system's cooling function. If the heating purpose has been achieved, the seat heater should be turned off promptly. The rear window heater should also be turned off when there is no fog or ice. 3. Use gears correctly: Match the gear to the speed; avoid high speed with low gear or low speed with high gear. Shift gears in advance, ensuring the gear matches the appropriate speed, and avoid driving at high speeds with low gears or low speeds with high gears.

I think 14L/100km fuel consumption depends on the situation. I drive a midsize SUV with a 2.0T engine, and 14L is quite normal during rush hour in the city with AC on. Once on a long trip with friends, highway fuel consumption dropped to 9L. However, if a compact sedan burns 14L, that's indeed on the high side. Research shows ideal fuel consumption for small cars is 7-8L, while 10-12L is acceptable for midsize vehicles. Factors like insufficient tire pressure or a fully loaded trunk can secretly increase fuel usage. I recommend tracking fuel consumption under different road conditions for a month - for an SUV, 14L in pure city driving isn't outrageous.

As an experienced driver who frequently goes on road trips, 14 L/100km is considered moderately high. My experience shows that a new car's fuel consumption becomes most accurate after its first maintenance, but it will gradually increase if not properly maintained over time. Last week, while helping a friend check his decade-old car, cleaning the throttle body and fuel injectors reduced the fuel consumption from 14 to 11 L/100km. Warming up the car for more than three minutes in winter also consumes extra fuel, so remember to check the spark plugs and air filter during seasonal maintenance. It's normal for air conditioning to increase fuel consumption by 10% in summer. A new car during its break-in period might reach 15 L/100km, but if it doesn't drop below that after 3,000 kilometers, it's worth paying attention to.

After comparing numerous vehicle data, whether 14L/100km is considered high mainly depends on three factors: engine displacement, road conditions, and driving habits. My 2.5L naturally aspirated car consumes 11L/100km in suburban areas, but surges to 15L in congested urban sections. A colleague's hybrid model only uses 7L on the same route. Aggressive acceleration and braking significantly increase fuel consumption - one test showed gentle driving saved 3L/100km. For domestic compact SUVs, under 12L is normal, while American brands typically consume 1-2L more. If the average speed is below 20km/h, 14L/100km falls within reasonable range.
