Does the Engine Oil Passage Need Cleaning?

Engine oil passages do require cleaning. If you haven't completed high-speed running-in yet, you can wait until after the first maintenance to perform high-speed running, then clean the engine oil circuit during the next maintenance. Additionally, engine cleaning should be performed during every maintenance service. The reasons why engine cleaning is necessary are as follows: 1. If the engine isn't cleaned, once clogged, it will affect engine performance. Dirt remaining on internal engine components will accelerate wear, causing insufficient oil pressure that leads to valve noise and engine knocking, ultimately shortening the engine's lifespan. 2. Due to the characteristics of electronic engine control, wax and gum deposits from gasoline remain after each combustion cycle. Repeated heating hardens these deposits, forming carbon buildup. When carbon accumulates on valves, part of the injected fuel gets absorbed, diluting the actual air-fuel mixture entering the cylinders. This causes poor engine performance and various abnormalities. In severe cases, it may result in incomplete valve sealing, causing complete cylinder failure due to lack of compression, or even valve sticking. This creates interference between valves and pistons, eventually damaging the engine.

Differences Between 6-Seater and 7-Seater Vehicles

Differences between 6-seater and 7-seater vehicles are as follows: 1. Seating arrangement: 7-seater vehicles adopt a 2-2-3 layout, while 6-seater vehicles use a 2-2-2 layout, making the third row relatively more cramped. 2. Annual inspection difference: There are also distinctions in vehicle inspections. 6-seater vehicles are exempt from inspection for the first six years, whereas 7-seater vehicles require biennial inspections. First, let's discuss 6-seater vehicles. Vehicles with six or fewer seats don't need on-site inspections within six years, but require annual inspections thereafter. Compared to 7-seaters, 6-seaters offer more convenience regarding inspections. 3. Compulsory traffic insurance cost difference: For 7-seater vehicles, the first-year compulsory insurance typically costs around 1,100 yuan. From the second year onwards, premiums adjust based on the vehicle's previous year's driving record. If accidents occur in the first year, the second-year premium increases by 30%.

Will the Car Lock Automatically with the Key Inside?

If the car key is left inside the vehicle, the car will automatically lock itself. After the engine is turned off, if the doors are closed without taking the key out, both the doors and the trunk will automatically lock after a few minutes. Here is some relevant information about the automatic locking feature with the key inside: The original intention of this function is to prevent the owner from forgetting to lock the car. A car key is a tool used to start and stop the car. Modern car keys use chips, which are part of a magnetic chip system. The reading coil in the car's ignition lock cylinder reads the chip in the key, and each chip contains fixed digital information. A remote key allows the user to lock and unlock the car from a distance without inserting the key into the lock. It emits a weak radio wave from the owner's vicinity, which is received by the car's antenna. The electronic control unit (ECU) then identifies the signal code, and the system's actuator performs the locking or unlocking action. This system mainly consists of two parts: a transmitter and a receiver.

How to turn off the ECO mode in Levin?

Levin's ECO mode is an energy-saving mode. Press the SPORT button next to the handbrake, and the ECO light will turn off. The car will then be in sport mode, with increased engine speed, enhanced power, and higher fuel consumption. When the car is turned off and restarted, it will automatically return to the energy-saving mode. Here is more information about the ECO mode: 1. The ECO mode primarily operates during vehicle movement by comprehensively analyzing and judging factors that affect fuel consumption, such as automatic transmission gear, engine speed, vehicle speed, braking, and transmission oil temperature. The ECU control unit calculates the optimal fuel amount to supply the engine, effectively reducing fuel consumption compared to normal driving mode. 2. The ECO mode acts like an intelligent fuel-saving co-driver, guiding and reminding the driver to adopt appropriate driving habits. When the optimal fuel supply is achieved, the dashboard will display a green "ECO" indicator. However, if the accelerator is pressed hard for rapid acceleration or when encountering uphill driving, the "ECO" indicator will disappear.

Is the BMW 530 Full-Time Four-Wheel Drive?

The BMW 530 is not full-time four-wheel drive; it uses an on-demand four-wheel drive system. The on-demand four-wheel drive system can automatically identify driving conditions and switch between two-wheel drive and four-wheel drive modes based on changes in the driving environment. On low-traction roads such as bumpy, hilly, or winding surfaces, the vehicle automatically sets to four-wheel drive mode. On relatively flat urban roads, the vehicle will switch to two-wheel drive on its own. The BMW 530 is a mid-to-large luxury car under the BMW brand, measuring 5087mm in length, 1868mm in width, and 1500mm in height, with a wheelbase of 3108mm. It is equipped with high and low power 2.0-liter turbocharged engines. The low-power version of the 2.0-liter turbocharged engine has a maximum power of 184 horsepower and a maximum torque of 290 Nm, with a maximum power speed range of 5000 to 6500 rpm. The high-power version of the 2.0-liter turbocharged engine has a maximum power of 252 horsepower and a maximum torque of 350 Nm, with a maximum power speed range of 5200 to 6500 rpm.

Where to Check the Production Date of Vehicle Tires?

Tire production dates can be found on the sidewall. The production date of a tire is usually represented by a four-digit number, where the first two digits indicate the week of production and the last two digits represent the year. Here are specific details about tires: 1. The shelf life of tires is generally 5 years. When replacing tires, the production date should not exceed 3 years. For example, "3512" means the tire was produced in the 35th week of 2012. 2. Tires are an essential part of a vehicle, consisting of ring-shaped rubber products mounted on metal rims. If the production date is unclear, it is advisable not to purchase the tire to avoid buying overstocked or retreaded tires. 3. The 11-digit number and letters immediately following the "DOT" marking on the tire sidewall represent the tire's identification number or serial number. The last four digits of the serial number indicate the tire's production date.
