Castrol 5w40 fully synthetic oil can run 8000 to 10000 kilometers. What is fully synthetic oil: Fully synthetic oil is laboratory-synthesized oil. It is designed to provide stronger engine wear protection and high-temperature protection. Fully synthetic oil can also reduce resistance generated within the engine, thus delivering greater horsepower and higher fuel efficiency compared to conventional lubricants. Advantages of fully synthetic oil: Fully synthetic oil has a wider temperature range compared to semi-synthetic and mineral oils; Synthetic oil is less prone to deterioration, has lower evaporation loss, and a longer service life than conventional oils; It has excellent chemical stability, good radiation resistance, high oil film strength with less foaming, superior lubrication, and reduced wear; Fully synthetic oil has minimal thermal degradation, saves fuel, and provides better engine protection.

Is there no inspection sticker for vehicle inspection in 2021?

2021 vehicle inspection does not have an inspection sticker. According to the notice from relevant departments, electronic annual inspection labels have been implemented nationwide since June 2020. When vehicle owners go for annual vehicle inspection, no paper inspection label will be issued after the vehicle passes the inspection. Here are some precautions regarding vehicle inspection: 1. Keep the vehicle clean and tidy: To leave a good first impression on the inspector, it is recommended to wash the vehicle before the inspection, and minor scratches on the vehicle will be less noticeable, making it easier to pass the inspection. 2. Handle vehicle violations: Ensure all vehicle violations have been processed before the inspection, otherwise it will affect the inspection progress. Not only will the annual vehicle inspection fail to be completed, but time will also be wasted queuing at the traffic police station to handle violations. It is recommended to check for any vehicle violations before the inspection. 3. Prepare relevant materials: Before the inspection, prepare the necessary materials in advance, including the handler's ID card, the valid compulsory traffic insurance policy for the vehicle (copies, originals, electronic policies, or duplicates with the insurance company's red stamp within the validity period are acceptable, and the compulsory insurance must include the vehicle and vessel tax), and the vehicle registration certificate. 4. Make an appointment in advance: Try to avoid peak periods for vehicle inspection. Before the inspection, you can call the inspection station for consultation or make an online appointment. Some time ago, Anche Inspection's vehicle inspection appointment platform was highly recognized by customers upon its launch. The appointment platform can set the number of appointments within a certain time period. Once the number is reached, no further appointments can be made during that time, effectively reducing crowd gatherings, minimizing waiting time, and scientifically controlling the epidemic.

How to Adjust the Brakes on a Truck with Air Brakes?

Turn the screw in the opposite direction to tighten it, then loosen it three turns in the forward direction. Relevant details are as follows: 1. Air Brakes: Air brakes are a type of braking system. In vehicles, a series of specialized devices are used to apply a certain force from the external environment (primarily the road surface) to specific parts of the vehicle (mainly the wheels), thereby enforcing a certain degree of braking. This system is collectively referred to as the braking system. 2. Classification: Based on their function, vehicle braking systems can be divided into service brakes (air brakes), parking brakes, emergency brakes, and auxiliary brakes. Parking brakes can further be categorized into central disc brakes and spring brake chambers, with the latter commonly known as "spring brakes."

How to Use the 2 and L Gears in an Automatic Transmission?

2 and L gears are low-speed modes on an automatic transmission. For a 5-speed automatic transmission, when shifted into D (Drive) gear, the transmission will only move between gears 1-5. However, when the gear is set to 2, it will only shift between gears 1-2 and will not switch to higher gears like 3-4-5. In L (Low) gear, the transmission will stay in the lower gears. The difference between L and 2 gear is that in L gear, the transmission may still shift up to 3rd gear. Here are the details: 1. L gear: The L gear in an automatic transmission is the climbing gear, also known as the low-speed gear. When in L gear, the transmission only shifts between 1st and 2nd gears, primarily used for climbing hills. 2. Function: L stands for LOW, meaning low-speed gear. The L gear is often used when driving up steep hills, as it allows the engine to provide more power, making the climb easier and smoother.

What Causes a Truck Not to Consume Urea?

If you notice that the vehicle's urea has not been consumed or the emission warning light is on, it may indicate that the SCR system is not functioning (commonly referred to as not "burning" urea). This issue cannot be resolved by DIY methods and requires immediate inspection and repair at a professional 4S shop. Possible specific causes include: damaged urea pump, blocked urea lines, or clogged nozzles. The impacts are as follows: 1. Environmental Pollution: Diesel vehicles without urea can severely harm the ecological environment, and it is also prohibited by national laws and regulations. 2. Reduced Power: This is not a direct result of not using urea, but rather because the engine's electronic control system limits torque output when it detects no urea injection and excessive tailpipe emissions. 3. Damage to the SCR Injection System: Long-term absence of urea may cause crystallization blockages in the SCR system's nozzles, lines, and urea pump, or damage due to high temperatures.
