According to the information released by the Ministry of Industry and Information Technology, the combined cycle fuel consumption of this vehicle is 7.5L/100km. Below is some related information about engine oil: 1. The role of engine oil: Also known as engine lubricant, English name: Engine oil. With a density of approximately 0.91×10³ (kg/m³), it serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and cushion shocks in the engine. It is often referred to as the 'blood' of a car. 2. Engine oil consists of two parts: base oil and additives: Base oil is the main component of lubricating oil, determining its basic properties. Additives compensate for and improve the shortcomings of the base oil, providing certain new properties, making them an important part of lubricating oil. 3. Synthetic oils are divided into: Full synthetic and semi-synthetic. Lubricating base oils are mainly categorized into mineral base oils and synthetic base oils. Mineral base oils are widely used and account for a large proportion (about 95% or more), but in some applications, products blended with synthetic base oils must be used.

The fuel consumption of the Boyue depends on the specific model. I've been driving the 1.8T version for over a year, with an average combined fuel consumption of around 8.5 liters per 100 kilometers. In city traffic with congestion, it can rise to 10 liters, while on smooth highways, it drops to just over 7 liters. Personal driving habits have a significant impact: gentle acceleration and steady driving save fuel, whereas aggressive throttle or sudden braking increases consumption. Road conditions also play a key role—fuel usage is higher during rush hour commutes but lower on weekend outings. I make it a habit to record each refueling and calculate manually, which is more reliable than the dashboard data. After regular maintenance, like changing the air filter, I noticed a slight drop in fuel consumption. Using the heater in winter or air conditioning in summer increases consumption by 5% to 10%. Overall, as an SUV, the Boyue's fuel efficiency is mid-range for its class, and with experience, learning how to optimize it makes driving quite satisfying.

From a technical perspective, fuel consumption is largely determined by the Boyue's powertrain. The mainstream 1.8T turbocharged engine has a combined fuel consumption of 8 to 9L/100km, while the 1.5T plug-in hybrid version can reduce it to 5 to 6L/100km. Engine efficiency is influenced by compression ratio and valve control; the heavier body weight and higher drag coefficient of SUVs result in higher fuel consumption compared to sedans. Proper transmission tuning can optimize performance, with automatic transmissions being more fuel-efficient during cruising. Using air conditioning increases fuel consumption by about 10% due to the additional compressor load. Poor maintenance, such as dirty engine oil or low tire pressure, can also increase fuel consumption. It is recommended to conduct regular inspections and maintain normal tire pressure to reduce rolling resistance, thereby keeping fuel consumption stable within the theoretical range.

From an economic perspective, calculating fuel costs directly is the most practical approach. The Boyue 1.8T averages 9L/100km. With 92-octane gasoline priced at 8 yuan per liter, the fuel cost per kilometer is approximately 0.72 yuan. Driving 15,000 kilometers a year would cost just over 10,000 yuan, which is slightly more expensive than fuel-efficient cars. The hybrid version has a combined fuel consumption of 6L, saving 30% on fuel costs, amounting to only about 7,000 yuan annually. Improving driving habits, such as smooth acceleration, less sudden braking, and using cruise control on highways, can further reduce costs by 5%. Regular engine maintenance and replacing filters can also lower fuel consumption. Using air conditioning with moderate temperature settings saves a bit more. Crunching the numbers, driving sensibly can save hundreds of yuan each month.
