What is the fuel consumption for a 1.8L displacement engine?
2 Answers
Fuel consumption for a 1.8L displacement engine is 6~8L. Vehicle fuel consumption is calculated based on the fuel consumed per 100 kilometers traveled (commonly referred to as 100 kilometers). For example, when people say "8 liters" or "9 liters," they mean 8 liters or 9 liters per 100 kilometers. Methods to reduce fuel consumption: Maintaining normal tire pressure levels is also a good way to reduce fuel consumption. If tire pressure is insufficient, rolling resistance will increase significantly. According to tests, if tire pressure is 2 psi (pressure unit: pounds per square foot) below the specified value, fuel consumption will increase by 1%. Additionally, misaligned or excessively worn tires may also increase fuel consumption. Related information: Oxygen sensors are prone to silicon poisoning after prolonged use. Once this occurs, the electronic fuel injection system's computer cannot obtain information about the oxygen concentration in the exhaust pipe, often resulting in a higher concentration of the air-fuel mixture in the engine and increased fuel consumption. Similarly, when there is insufficient power, the oxygen sensor and fuel injector cannot function properly, leading to a richer air-fuel mixture and higher fuel consumption. Typically, replacement is needed at 80,000 to 110,000 kilometers.
I've driven various 1.8L displacement cars, and fuel consumption is far from a simple number—it depends on driving style, vehicle model, and road conditions. For example, in city traffic with stop-and-go driving, it can spike to 10 liters per 100 km; on the highway at a steady speed of 60-90 km/h, it can drop to 6-7 liters. Vehicle models also make a big difference: SUVs are heavier and often exceed 9 liters, while lighter sedans stay lower, around 7-8 liters. With 30 years of driving experience, I've found the key to fuel efficiency is smooth driving—avoiding sudden acceleration and hard braking, and not running the AC at max all the time. Tire pressure matters too; underinflated tires increase resistance, boosting fuel consumption by over 5%. Regular engine maintenance, like oil changes, is crucial, and a dirty air filter also wastes fuel. Overall, 1.8L engines average 7-9 liters, but it's best to test your specific car. Safe driving without speeding naturally leads to more stable fuel consumption.
