Can engine oils of different brands be mixed?

Engine oils from two different brands should not be mixed because the additives used in different brands of engine oil vary and can cause chemical reactions, leading to the oil becoming thicker or thinner, partially losing its lubricating properties. Mixing different brands of engine oil can result in: 1. Layering, turbidity, and deterioration of cleaning ability; 2. Abnormal exhaust emissions, as mixing different brands may cause unusual smoke from the exhaust; 3. Formation of sludge, which reduces the cooling effect of the lubricant, leading to higher engine temperatures and potential malfunctions; 4. Accelerated wear, as mixing oils can significantly alter their anti-wear properties, damaging the oil film and increasing the risk of wear between the piston and cylinder wall, potentially leading to piston ring breakage in severe cases.

How to Prevent Rain on Car Rearview Mirrors?

Methods to prevent rain on car rearview mirrors: Before driving in the rain, you can evenly apply soap to the car's rearview mirrors. After the soap hardens, wipe it off with a towel. This will form a wax layer on the glass surface, which has excellent water-repellent properties. Alternatively, you can use a water-repellent spray or solution. Apply it evenly to the rearview mirrors, and it will form a protective film with hydrophobic properties, effectively preventing fogging and ensuring clear visibility. Installing rain guards on the rearview mirrors can also help block rainwater and prevent it from accumulating on the mirror surface. However, rain guards do not solve the issue of fogging on the rearview mirrors.

How to Disable the Anti-lock Braking System?

Method to disable the anti-lock braking system: The ABS (Anti-lock Braking System) cannot be disabled as it is in a default active state. Unless there is a malfunction, the system remains on standby at all times. Whenever there is a tendency for the wheels to lock, the ABS system intervenes to prevent wheel lock-up. The primary function of the ABS system is to prevent the wheels from locking and losing directional control, rather than to shorten the braking distance. In some braking situations where the vehicle cannot come to a complete stop before colliding with an obstacle, the ABS ensures that the driver retains the ability to steer, allowing them to maneuver around the obstacle during braking to avoid an accident.

Where is the VIN code?

VIN code is usually located on the adhesive label or nameplate inside the driver's side door. More information about VIN is as follows: 1. VIN is the abbreviation for Vehicle Identification Number. 2. According to SAE standard (Society of Automotive Engineers), the VIN code consists of 17 characters, hence commonly known as the seventeen-digit code. 3. The VIN contains information such as the vehicle manufacturer, year, model, body type and code, engine code, and assembly location. Correct interpretation of the VIN code enables accurate diagnosis and maintenance.

How to Determine the National Emission Standard of a Vehicle?

Here are the methods to determine the national emission standard of a vehicle: 1. Check the vehicle's environmental protection label, which usually has clear markings on the back. 2. Visit the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center to inquire. 3. Take the vehicle registration certificate (original or copy) to the vehicle management office for inquiry. 4. For new cars, you can refer to the vehicle's factory certificate, which contains this information. However, the vehicle certificate is usually kept at the vehicle management office, so it's advisable to make a copy when purchasing a new car. 5. Make a rough estimation based on the year the vehicle was registered.

Can a vehicle undergo annual inspection in another location?

Vehicles can undergo annual inspection in another location. Currently, the traffic management authorities have fully implemented cross-province inspection services for small cars, trucks, and medium-sized buses. Applicants can directly have their vehicles inspected in provinces other than where the vehicle is registered and obtain the inspection qualification mark without needing to go through the entrustment inspection procedure. However, large passenger buses and school buses cannot be inspected in another location and must return to the vehicle's registration location for inspection. The annual inspection process includes: Checking whether the engine, chassis, body, and auxiliary equipment are clean, complete, and functional, whether the paint surface is uniform and aesthetically pleasing, whether the main assemblies have been replaced, and whether they match the initial inspection records; verifying whether the vehicle's braking performance, steering control, lights, exhaust, and other safety features comply with the "Technical Conditions for Safe Operation of Motor Vehicles"; Inspecting whether the vehicle has been modified, reconstructed, or altered, whether the driving license, license plate, and vehicle records match the actual condition of the vehicle, and whether any changes have been made, and whether approval and modification procedures have been completed; Checking whether the license plate, driving license, and enlarged license plate characters printed on the vehicle are damaged, altered, or illegible, and whether they need to be replaced; For large vehicles, verifying whether the unit name or the name of the street, township, or town where the vehicle is located and the maximum seating capacity in the driver's compartment are printed in Chinese imitation Song font on both sides of the door as required; For trucks, checking whether the rear tailgate (including the trailer's rear tailgate) has the vehicle number printed in 2~3 times enlarged size as required, and whether the words "individual" are printed on both sides of the door for individual or joint-operation vehicles. The characters must be clear, and unit codes or other patterns are not allowed (special circumstances require approval from the vehicle management office).
