What is considered normal fuel consumption for city driving?

[SanHaley]

Vehicle fuel consumption varies under different road conditions, typically ranging between 7-11 liters per 100 kilometers, and is not a fixed value—sometimes it can be even higher. On highways, consumption is around 7-8 liters, while in city driving, it's between 8-11 liters. The reasons for increasing fuel consumption are as follows: 1. Temperature effects causing fuel consumption fluctuations: Generally, in winter when temperatures are low, fuel consumption increases significantly, almost comparable to summer air conditioning usage. This is because lower temperatures cause the engine to dissipate more heat. 2. Lack of regular vehicle maintenance: Dirty engine oil and air filters can also lead to increased fuel consumption. Contaminated oil results in poor lubrication, increasing resistance in the engine's moving parts and requiring more energy to overcome this resistance, thereby raising fuel consumption. 3. Spark plug replacement needed: Spark plugs are often overlooked. Even if they continue to function, worn spark plugs can cause delayed ignition due to insufficient energy, missing the optimal ignition timing.
