What are the reasons for the high fuel consumption of the Reiz?
2 Answers
The reasons for the high fuel consumption of the Reiz are as follows: 1. Poor fuel quality: The quality of fuel directly affects fuel consumption. Inferior fuel with too many impurities can clog the fuel system. A clogged fuel system leads to incorrect air-fuel ratio, excessively rich mixture, and incomplete combustion of fuel, resulting in increased fuel consumption. 2. Damaged oxygen sensor: The oxygen sensor primarily monitors the air-fuel ratio of the engine. Once damaged, it can cause an imbalance in the air-fuel ratio, leading to higher fuel consumption. 3. Poor driving habits: Poor driving habits, such as sudden stops and starts, and aggressive acceleration, can significantly increase fuel consumption.
Fellow Mark X owners might have noticed that this car is quite fuel-thirsty, and I have to say driving this model itself is bound to consume more fuel. The Mark X is equipped with a large-displacement V6 engine, rear-wheel-drive layout, and its weight is also a factor. In daily city driving, 12-15 liters per 100 kilometers is considered normal. However, if the fuel consumption is unusually high, it might be worth investigating the issue. For example, my car once experienced a sudden spike in fuel consumption, and upon inspection, it turned out the oxygen sensor was faulty. This component inaccurately monitors exhaust emissions, causing the engine to inject more fuel. Poor maintenance can also affect fuel efficiency, such as severe carbon buildup, clogged air filters, or faulty spark plugs that fail to ignite properly—all of which should be checked. Neglecting to replace transmission fluid can also hinder performance, especially in older cars where solenoid valves are prone to sticking. While upgrading to larger wheels might look stylish, the increased rolling resistance significantly boosts fuel consumption. It's best to focus on these areas when diagnosing the cause.
