Fully synthetic oil is generally recommended to be changed every year or approximately every 12,000 kilometers, though the exact interval should be determined based on the vehicle's condition. Here are the specific details about fully synthetic oil: Advantages: Fully synthetic oil has a stable molecular structure with uniform molecule sizes, offering excellent lubrication and oxidation resistance. Replacement Interval: Due to poor road conditions in China, such as frequent traffic jams and stop-and-go driving, the oil degrades faster, shortening its service life. Therefore, the replacement interval for fully synthetic oil in China is relatively shorter compared to other countries, typically around 12,000 kilometers.

What does it mean when a car displays 'Check Engine System'?

The reasons why a car displays 'Check Engine' are as follows: The message 'Check Engine System' means that the engine needs to be inspected to see if there is a fault in the emission system or an issue with the oxygen sensor. The owner should take the car to a 4S shop to read the fault code and identify the specific cause. Extension: 1. The engine consists of three major parts and five service systems: the engine block assembly, the crank-connecting rod mechanism, the valve train, the ignition system, the starting system, the lubrication system, the cooling system, and the fuel supply system. 2. The functions and basic components of each part are as follows: the engine block assembly supports the entire engine and also houses the crankcase, cylinders, etc.; the crank-connecting rod mechanism converts the reciprocating motion of the piston into the rotational motion of the crankshaft, which is then output, including components like the connecting rod and crankshaft; the valve train supplies fuel and air to the cylinders and expels exhaust gases, composed of components such as tappets, valves, and control circuits.

What is the fuel tank capacity of the Borgward BX5 in liters?

Borgward BX5 has a fuel tank capacity of 60 liters, as announced by the automobile manufacturer. Owners who have purchased the Borgward BX5 can also check this information on the vehicle's configuration sheet. The Borgward BX5 requires 95-octane fuel, with a fuel consumption ranging from 5.8 to 7.6 liters per 100 kilometers. A full tank can cover a distance of approximately 500 to 600 kilometers. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically done by observing the fuel gauge inside the vehicle. Under normal circumstances, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel mid-journey. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the manufacturer's specified tank capacity is measured from the bottom of the tank to the safe fill level, leaving some space between the safe fill level and the tank opening. This space ensures that the fuel can expand when temperatures rise without overflowing. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.

How to Display the Remaining Mileage on the Fuel Gauge in a Land Rover?

Land Rover displays the remaining mileage that can be driven with the current fuel level as follows: 1. Press the brake pedal and press the one-touch start button. At this time, the dashboard will light up, indicating that the vehicle's power is fully connected. 2. Then press the function selection button on the multifunction steering wheel and press the OK button to confirm the operation. At this point, the remaining mileage based on the fuel level will be displayed on the dashboard. The fuel gauge shows 0 km under the following circumstances: 1. When the fuel gauge shows 0 km, the fuel warning light comes on. This is actually just a reminder to refuel, and there is still some fuel left in the tank. 2. In this situation, a typical family car can still drive about 20-30 km, but the exact distance depends on the vehicle model, fuel tank size, and fuel consumption. In the city, you can usually make it to a gas station. If you're on the highway, it is recommended to drive at a steady speed in the right lane and turn off the air conditioning to maximize fuel efficiency.

What is the Stella car?

Currently, there is no Stella; it should be Tesla. Tesla is an American electric vehicle and energy company that manufactures and sells electric cars, solar panels, and energy storage devices. Headquartered in Palo Alto, the company was named 'Tesla Motors' by its founders in honor of physicist Nikola Tesla. Tesla's vehicle lineup includes the Model 3, Model S, Model X, and Model Y. Taking the Model S as an example: it is a mid-to-large-sized sedan with dimensions of 4979 mm in length, 1964 mm in width, and 1445 mm in height, and a wheelbase of 2960 mm. The Model S comes in two configurations: a Long Range version and a Performance version. The Long Range version features a front motor with a maximum power of 202 kW and a maximum torque of 404 Nm, and a rear motor with a maximum power of 285 kW and a maximum torque of 440 Nm. The Performance version has a front motor with a maximum power of 202 kW and a maximum torque of 404 Nm, and a rear motor with a maximum power of 375 kW and a maximum torque of 650 Nm.

How to Adjust the Rear of the Car to the Left?

When reversing, turning the steering wheel to the left will make the rear of the car move to the left, while turning it to the right will make the rear move to the right. The steering method is the same as when driving forward. Here are some precautions for reversing: 1. Before reversing, always check the current environment and terrain to see if there are any people or obstacles around. If there are, extra caution is needed. 2. Try to reverse at a slow speed, which helps in braking promptly. If an obstacle or person suddenly appears, timely braking can avoid unnecessary trouble. 3. While reversing, keep your eyes on the rearview mirror and the front, and do not lean your head out of the car to prevent accidental injuries. 4. If the reversing space is not spacious enough, be careful not to reverse too much; just enough to move forward is sufficient, as reversing is generally less safe than driving forward. 5. Remember not to focus only on the rear while reversing. Often, focusing solely on the rear can lead to the side mirrors scraping someone else's car or object, causing unnecessary disputes. Maintaining a slow speed and paying attention to both the front and rear will ensure a smooth reversing process.

Is the Subaru Outback a Domestic Car?

Subaru Outback is an imported car model. More relevant information is as follows: 1. Subaru is the only automobile manufacturer besides Porsche that uses a horizontally opposed engine. The pistons on either side of the crankshaft in an opposed engine resemble two fists facing each other. The Outback is equipped with a 6-cylinder 3.0-liter horizontally opposed engine, which has the advantage of a lower center of gravity compared to a V-type engine, less vibration, and the power output shaft aligns with the drive shaft direction, eliminating the need to change the power output direction, thus achieving high transmission efficiency. However, the structure of the horizontally opposed engine is relatively more complex. 2. An opposed engine can be considered as a V-type engine with an angle of 180 degrees. Comparatively, its valve system is distributed at both ends, and the ignition interval is unique, making maintenance somewhat difficult. The lubrication system has relatively higher technical requirements, and the engine occupies more space, making its application more troublesome compared to a V-type engine. Particularly due to the lubrication system and the large space it occupies in the engine compartment, only Porsche and Subaru use horizontally opposed engines.
