The national regulatory standard is 0.3 liters of oil consumption per thousand kilometers. The following explains the reasons for engine oil consumption: 1. Oil is used to lubricate pistons, piston rings, and cylinders: When the piston moves downward in the cylinder, it leaves a thin oil film on the cylinder wall; during vehicle deceleration, the high negative pressure generated draws this oil into the combustion chamber; this oil, along with some of the oil film remaining on the cylinder wall, is burned during combustion due to high temperatures. 2. Oil is used to lubricate valve stems: Some oil will be drawn in with the intake air and burned together with the fuel; high-temperature exhaust gases will also burn the oil used to lubricate the exhaust valve stems.

Does the Nissan Sylphy require bumper removal for fog light replacement?

The Nissan Sylphy does not require bumper removal for fog light replacement. Below is relevant information about fog lights: 1. Function: The purpose of fog lights is to make the vehicle visible to others during foggy or rainy conditions when visibility is significantly affected by weather. Therefore, fog light sources need to have strong penetration capability. Most vehicles use halogen fog lights, while LED fog lights represent a more advanced option. 2. Activation conditions: According to traffic regulations, when visibility is between 100-200 meters, fog lights, low beams, position lights, and tail lights must be activated. The speed should not exceed 60 km/h, and a distance of over 100 meters should be maintained from the vehicle ahead.

What type of engine oil does the Rena use?

The engine oil specification for the Rena is 5W-20, which is the original Beijing Hyundai factory oil. For later maintenance and oil changes, you can choose international brands such as Mobil, Shell, Castrol, and Total, or domestic brands like Great Wall, Kunlun, Tongyi, and Longpan. The official manual recommends the 5W-20 specification, and any oil of the same specification can be used. The viscosity of engine oil changes with temperature, so it's important to pay attention to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother for the car. The second number represents the kinematic viscosity of the oil at 100°C. A higher number means the oil can maintain its viscosity index better at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the Rena's engine oil is as follows: Wait for the engine temperature to cool down, allowing the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan underneath to catch the old oil until no more oil flows out. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain out; Use a special wrench to remove the oil filter; Apply some oil to the oil seal of the new oil filter and tighten it clockwise by hand; Add the new oil through the engine valve cover filler port. Typically, fill up to three-quarters of the oil bottle; Start the engine and let it run for 5 minutes, checking for any leaks around the oil drain plug and oil filter. If there are leaks, perform necessary repairs; After stopping the engine, pull out the oil dipstick and check that the engine oil level is within the standard range.

How Long Can China V Vehicles Be Driven After China VI Implementation?

After the implementation of China VI standards, China V vehicles can still be driven for at least 13 more years, for the following reasons: 1. Large market share: Compared to China II and China III vehicles, China IV and China V vehicles account for over 60% of the market share. In 2017, the number of China IV and China V vehicles nationwide accounted for 69.5% of all vehicle types, totaling nearly 150 million vehicles. 2. Slowing down of traffic restriction policies: Current traffic restriction policies are slowing down. A report in China Daily predicted that the buffer period for traffic restriction policies would be more than 3 years. Moreover, because traffic restriction policies actually involve the exercise of citizens' property rights, the 2015 revision of the Air Pollution Prevention and Control Law removed the authorization that allowed local governments to impose traffic restrictions on motor vehicles.
