Why is the fuel consumption of Refine so high?
2 Answers
There are many factors that can lead to excessive fuel consumption, such as driving habits (sudden acceleration, sudden braking, coasting in neutral, speed and gear mismatch), low tire pressure, use of low-quality fuel, ignition system failure, and electronic control system failure. These issues will all increase the vehicle's fuel consumption. The specific reasons for high fuel consumption are as follows: 1. Idling: When the car is idling, fuel continues to be consumed while the mileage does not increase, inevitably leading to higher fuel consumption. 2. Warm-up time: The fuel injection volume is very large during idle warm-up. Prolonged warm-up before driving in winter will cause an increase in fuel consumption. 3. Driving conditions: Frequent starts and stops in traffic jams will inevitably lead to wasted fuel. Choosing a good driving route is an effective way to reduce fuel consumption. 4. Driving habits: Poor driving habits have a significant impact on fuel consumption. Sudden acceleration and braking waste a lot of fuel and increase the wear on brake pads and discs.
As a veteran driver who has been driving the Refine for many years, I can relate to the frustration of high fuel consumption. The main issue lies in the somewhat outdated engine design, especially in older models where the powertrain isn't very efficient, leading to noticeably higher fuel usage during acceleration. Additionally, the vehicle's weight is significantly heavier than typical sedans. When fully loaded with passengers or cargo, the engine has to work much harder, causing fuel consumption to spike. From my daily driving experience, regular maintenance is crucial—things like a dirty air filter or underinflated tires can increase fuel consumption by over 10%. On highways, the high wind resistance also drives up fuel usage. Overall, using better engine oil or maintaining speeds between 60-80 km/h can help somewhat, but it still consumes more fuel compared to newer models.
