What is considered high fuel consumption?

[VanReese]

Different cars, models, engine displacements, and driving habits all result in varying fuel consumption. Generally, for a family sedan with around a 1.6-liter engine displacement, the fuel consumption per 100 kilometers will be around 6-8 liters. Below is an introduction related to fuel consumption: Habits and road conditions: Fuel consumption is greatly influenced by driving habits and road conditions. Avoid stomping on the accelerator; gradual acceleration when starting is the most fuel-efficient. To save fuel, avoid pressing the accelerator heavily when starting, as heavy acceleration can increase fuel consumption by 2 to 3 times compared to normal acceleration. Braking: Maintaining a safe distance and avoiding frequent braking saves more fuel. If you don't maintain a safe distance, you may need to brake frequently on the road. When braking, an automatic transmission car will downshift, requiring the car to accelerate again from a lower gear. Starting from a standstill or in a low gear forces the engine to consume more fuel.

I've always been quite concerned about fuel consumption and often discuss it in car enthusiast groups. Actually, fuel efficiency largely depends on the vehicle model. For my compact sedan, getting over 9 liters per 100km in city driving is a bit excessive, since most similar models average around 7-8 liters. But for my friend's SUV, 12 liters is considered normal. The judgment criteria are simple: first, check the official fuel consumption data from the Ministry of Industry and Information Technology—if your actual consumption is over 30% higher than that, you should pay attention. Then compare it with vehicles of the same displacement. For example, 1.5T cars generally consume 6-8 liters per 100km, so if yours hits 10 liters, there's likely an issue. For cars older than five years, a gradual increase in fuel consumption is normal, but a sudden spike is probably due to carbon buildup or a faulty oxygen sensor.

As an experienced driver, I believe fuel consumption standards shouldn't be applied uniformly. I've driven turbocharged cars that easily achieve 6L/100km on highways, but it would be impressive if a small-displacement naturally aspirated car could match that. Generally, fuel consumption above 10L/100km for sedans and 13L/100km for SUVs is considered relatively high. It's also important to consider driving conditions - there's a big difference between daily city traffic jams and weekend highway driving. My advice is to track fuel consumption for three months. If you notice abnormalities, check tire pressure first. Last time my underinflated tires increased fuel consumption by 1L/100km. Also, minor issues like worn spark plugs or clogged air filters can significantly increase fuel consumption, so timely maintenance can save you a lot of money.

From the perspective of vehicle operating costs, I think high fuel consumption mainly depends on how it affects your wallet. With 92-octane gasoline now costing over 8 yuan per liter, a regular family sedan consuming 10L per 100km means commuting expenses of around 600 yuan per month can feel quite painful. Last time I drove a shared car, I noticed Japanese hybrids only use about 4L, while some American cars can easily consume 12L, which is really shocking. Normal reference standards: compact cars (A-segment) shouldn't exceed 8L, midsize cars (B-segment) shouldn't exceed 10L, and SUVs within 15L are acceptable. But be aware that cold starts and air conditioning affect consumption - especially in summer when AC use can increase fuel consumption by 10%, and short trips may double fuel consumption, which is normal and nothing to worry too much about.
