What is the actual fuel consumption of the BMW 730?

[VanEmmanuel]

The official combined fuel consumption of the BMW 7 Series is 6.4-12.6L/100km, while actual fuel consumption reported by some owners ranges from 9.9-13L/100km. The actual fuel consumption may fluctuate by about 10% depending on real-world driving conditions. The reasons for increasing fuel consumption are as follows: 1. Temperature effects causing fuel consumption fluctuations: In winter, lower temperatures generally lead to slightly higher fuel consumption, almost comparable to using air conditioning in summer. This is because low temperatures increase heat dissipation from the engine. 2. Lack of regular vehicle maintenance: Dirty engine oil and air filters can also increase fuel consumption. Contaminated oil leads to poor lubrication, causing increased resistance in engine components and requiring more energy to overcome this resistance, thereby increasing fuel consumption. 3. Spark plug replacement needed: Spark plugs are often overlooked. Even if they still function, worn spark plugs can cause delayed ignition due to insufficient energy, missing the optimal ignition timing.
