What does SM grade engine oil mean?

SM grade engine oil refers to the API engine oil quality classification. API is the abbreviation for the American Petroleum Institute. The API classification represents the quality grade of engine oil, using simple codes to describe the working capability of engine oil. Engine oil grades are divided into SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, and SN levels, with higher grades indicated by letters further in the alphabet. Among international brands, engine oil grades are mostly above SF level. The C-series represents oil for diesel engines. If both S and C letters are present, it indicates that the oil is suitable for both gasoline and diesel engines. Different quality grades of engine oil vary in terms of lubrication quality, cooling effect, oil film toughness, thermal stability, and anti-degradation capability.

Where is the installation location for the rear camera of a car dash cam?

Car dash cam rear cameras are generally installed at the top left or top right corner of the license plate, while some are mounted directly above the license plate. Depending on the brand and camera angle, there may be slight variations in the installation position, which requires adjusting while testing different locations. For installing a dash cam rear camera, it is necessary to visit a 4S store or a professional auto repair shop to have qualified personnel assist with the installation. When selecting the camera angle, a wider field of view is better for the car owner, as it captures more area on both sides of the vehicle. Night vision capability refers to a small light that turns on at night to enhance recording clarity.

How to Identify the Manufacturing Date on a Car Windshield?

Understanding the manufacturing date on a car windshield: The numbers and black dots on the glass indicate the production date. For example, the number 8 represents the year, meaning it was produced in 2008. If the black dot is before the 8, it indicates production in the first half of the year; if the dot is after the 8, it means production in the second half of the year. To identify the production date of imported car window glass, you can refer to the car glass code: Since car glass codes are usually overlooked, regardless of the glass specifications, there will be a corresponding number under each string of symbols indicating the production year. Typically, the glass marking consists of a combination of symbols, numbers, and English letters printed in the lower left corner of the glass, which includes information such as the car brand, glass brand, certification marks, glass type, and production date.

How to Forcefully Disable the Engine Lock?

Insert the ignition key into the ignition switch. The stop ECU command receiving coil emits electromagnetic energy, converts it into electrical energy, and temporarily stores it. Used to transmit the key code signal. After receiving the code signal from the key, the receiving coil amplifies it through an amplifier and transmits it to the stop ECU. The stop ECU compares it with the pre-stored identification code in the storage area. If they match, the engine can start.

What are common engine failures?

Common engine failures include: 1. Engine abnormal noise: Engine abnormal noise is divided into cold start noise and hot engine noise. During cold start, the oil pump cannot establish oil pressure and form an oil film immediately, causing parts to lack lubrication and produce noise; 2. Engine carbon deposits: Mainly caused by incomplete combustion during engine operation, combined with gummy substances generated from impurities in fuel and engine oil during combustion, which gradually form carbon deposits over time; 3. Frequently dirty throttle body: A dirty throttle body can cause high idle speed, poor acceleration, and engine warning light alerts; 4. Engine oil burning: Oil burning is usually caused by incorrect oil grade, aging or damaged valve stem seals, piston ring sealing failure leading to oil blow-by, or damaged oil separator/crankcase ventilation system.
