What is the real fuel consumption of the BMW 5 Series 525Li?

The 525Li has a total of 10 models currently on sale, which are divided into the following categories: The BMW 5 Series 2022 Modified 530Li xDrive M Sport Package and the BMW 5 Series 2022 Modified 530Li xDrive Luxury Package, equipped with a 2.0T 252-horsepower L4 engine, have an NEDC fuel consumption of 7.2L per 100km. The BMW 5 Series 2022 Modified 525Li Luxury Package and the BMW 5 Series 2022 Modified 525Li M Sport Package, equipped with a 2.0T 184-horsepower L4 engine, have an NEDC fuel consumption of 6.5L per 100km. The BMW 5 Series 2022 Modified 530Li Leading Luxury Package, BMW 5 Series 2022 Modified 530Li Executive Luxury Package, BMW 5 Series 2022 Modified 530Li Leading M Sport Package, BMW 5 Series 2022 Modified 530Li Premium Luxury Package, BMW 5 Series 2022 Modified 530Li Executive M Sport Package, and BMW 5 Series 2022 Modified 530Li Premium M Sport Package, all equipped with a 2.0T 252-horsepower L4 engine, have an NEDC fuel consumption of 6.7L per 100km. Different models have varying fuel tank capacities, and the distance that can be covered on a full tank of fuel is as follows: For the BMW xDrive series models equipped with a 2.0T 252-horsepower L4 engine, the fuel tank capacity is 68L, and the distance that can be covered on a full tank is 68/7.2*100=944km. For the BMW 525 series models equipped with a 2.0T 184-horsepower L4 engine, the fuel tank capacity is 68L, and the distance that can be covered on a full tank is 68/6.5*100=1046km. For the BMW 530 series models equipped with a 2.0T 252-horsepower L4 engine, the fuel tank capacity is 68L, and the distance that can be covered on a full tank is 68/6.7*100=1014km. The level of a car's fuel consumption is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. Specific factors that can increase a car's fuel consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not easing off the throttle in advance when approaching a red light, can increase fuel consumption. The car itself: Cars with larger engine displacements generally consume more fuel than those with smaller displacements because larger displacements usually mean higher power, requiring more gasoline for combustion and work. Cars with higher self-weight will have higher fuel consumption because greater self-weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases the car's resistance and fuel consumption. Low environmental temperatures result in lower engine block temperatures, making the injected gasoline less likely to vaporize during cold starts, requiring more gasoline to be injected for combustion, thus increasing fuel consumption. Additionally, low temperatures cause the engine's computer to control higher RPMs for warming up the engine, which also increases fuel consumption.

What kind of oil should be added to an Audi A4?

Audi A4 should use 0W40 fully synthetic oil or 5W40 fully synthetic oil. Engine oil, also known as motor lubricant, is composed of base oil and additives. The base oil is the main component of the lubricant, determining its basic properties, while the additives can compensate for and improve the shortcomings of the base oil's performance. The Audi A4 is a mid-size sedan with a body structure of 4 doors and 5 seats. Its dimensions are 4858mm in length, 1847mm in width, and 1439mm in height, with a wheelbase of 2908mm. In terms of power, this car is equipped with three types of engines: a low-power version 2.0-liter turbocharged engine, a medium-power version 2.0-liter turbocharged engine, and a high-power version 2.0-liter turbocharged engine.

Why Are Low Rolling Resistance Tires Not Popular?

Currently, low rolling resistance tires are still relatively popular. Here is relevant information about low rolling resistance tires: 1. Vehicle fuel economy is becoming increasingly important: On one hand, to conserve fuel resources, and on the other hand, to promote technological progress in the automotive industry and improve the energy-saving standard system for heavy-duty commercial vehicles, China implemented the first-phase fuel consumption standard for heavy-duty commercial vehicles in 2012, the second-phase standard in 2014, and the third-phase standard in 2019. Each update to the fuel consumption standard has tightened the fuel consumption limit by more than 10% compared to the previous phase, significantly reducing vehicle fuel consumption and increasing the demand for fuel-saving performance. Moreover, there will be a fourth-phase fuel consumption standard in the future. 2. Low rolling resistance tires excel in fuel-saving performance: Tire rolling resistance, also known as rolling friction, includes static friction and elastic losses. It is closely related to road type, tire structure and materials, vehicle load, etc., and is one of the three key performance indicators of tires. The three key performance indicators of tires are wear resistance (service life), rolling resistance (rolling friction), and wet grip (traction), known as the "Magic Triangle" in the tire industry. Often, improving one or two of these performance aspects leads to a loss in the others, making it difficult to achieve all three simultaneously. In Europe, tire rolling resistance levels are classified into seven grades: A, B, C, D, E, F, and G. In China, commonly used tires include large-pattern off-road tires, regular tires, and low rolling resistance tires, catering to different usage scenarios.

What are the symptoms of a broken engine mount?

Symptoms of a broken engine mount include: 1. Obvious engine vibration when reversing; 2. Noticeable shaking when starting the vehicle; 3. Significant engine vibration when the engine is cold, with noticeable improvement after warming up; 4. Steering wheel vibration during idle and noticeable brake pedal vibration. When the engine is running, it generates certain vibrations. The engine mount contains rubber components to eliminate resonance produced during engine operation. Some mounts also feature hydraulic oil pressure reduction, all serving the same primary purpose. If the engine mount is damaged, the vibrations from the engine will cause the entire vehicle body to vibrate.
