BMW M4 uses Castrol original equipment manufacturer (OEM) engine oil. Precautions for changing engine oil: 1. Pay attention to the timing of oil changes. The interval for oil changes is generally determined by mileage and time: conventional mineral oil should be changed every 5,000 kilometers or six months; semi-synthetic oil every 7,500 kilometers; and full-synthetic oil every 10,000 kilometers. 2. Be mindful of the amount of oil added. The oil level should be slightly below the mark on the dipstick and not overfilled. Engine oil is crucial for engine operation as it serves the dual functions of lubrication and heat dissipation. Therefore, the engine must never run without oil. However, excessive oil can increase the rotational resistance of the crankshaft, reduce engine output power, and cause the excess oil to enter the combustion chamber, leading to oil burning, blue smoke emissions, and increased fuel consumption. 3. Choose the right engine oil. In terms of types, the most common engine oils on the market today are semi-synthetic and full-synthetic oils. This is because modern car engines are increasingly advanced, requiring higher-quality engine oil. Comparatively, full-synthetic oil is of higher quality.

Does the Arrizo 5 headlight come with a lens?

Arrizo 5 headlights come with a lens. More details about the Arrizo 5 headlights are as follows: 1. The lens has strong light-gathering ability, so when used for road illumination, it not only brightens the road surface but also provides clear visibility. Due to minimal light dispersion, its light range is farther than that of ordinary halogen lamps. 2. The lens reflects the scattered light of the bulb into parallel beams, greatly enhancing the luminosity by hundreds or even thousands of times, ensuring sufficient illumination within a range of 150-400 meters in front of the car. 3. The lens refracts the parallel beams reflected by the reflector; it has a distinct cutoff line. In practical use, the lens has strong light-gathering ability. When properly installed on the headlight, it can clearly illuminate the road, and the light can present a left-low, right-high effect. Whether in low beam or high beam mode, the light does not scatter, but the ground illumination is excellent, avoiding glare and not affecting the normal driving of oncoming vehicles. This type of lens is commonly used in various car headlights for both low and high beams.

What is the reduction policy for the purchase tax on small-displacement vehicles in 2021?

2021 vehicle purchase tax rate is 10%. The vehicle purchase tax is a tax levied on entities and individuals who purchase specified vehicles within China. All purchases, including buying, importing, self-producing, receiving as gifts, winning as prizes, or obtaining through other means for self-use of taxable vehicles, are subject to the vehicle purchase tax. However, the state makes minor adjustments to the preferential policies for the purchase tax every year. The calculation formula for the taxable amount is as follows: 1. Calculation for self-use vehicles: out-of-pocket expenses × 10%, where out-of-pocket expenses do not include VAT; 2. Calculation for imported vehicles: taxable price = customs duty-paid price + customs duty + consumption tax taxable price × 10%; 3. Purchase tax amount: The purchase tax amount is 10% of the vehicle's selling price (excluding tax), and the formula is: new vehicle purchase tax amount = vehicle purchase price (including tax) / 1.17 * 10%.

How to Replace the Coolant in a Lavida?

Lavida coolant replacement method is as follows: Before completely replacing the coolant, conduct a thorough inspection to check for any signs of leakage or cracks in the pipelines, with a special focus on the five-way water pipe. The five-way pipe is named for its five interfaces connecting various parts, and the coolant is distributed to different sections of the car after flowing through it. If there is any coolant leakage in this section, replace the water pipe or re-secure the interface as needed. Drain the old coolant, then flush the liquid channels with clean water. Add clean water to the coolant reservoir and continue to pour water into the reservoir, allowing it to circulate continuously through the engine cooling system. Then, start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water flowing out from the reservoir will have a faint pink color. Continue adding clean water until clear water flows out. Remember to remove the heater hose and drain the water from the heater core. After draining for about an hour, add the new coolant through the radiator hose to allow it to flow quickly into the radiator. Then, add another bucket of coolant to the reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. During this time, the coolant level will drop slightly as air is expelled from the cooling system. Top up the coolant to the maximum mark "MAXT" on the reservoir.
