What is the SM grade of engine oil?

SM is one of the quality grades of engine oil, ranking third after SN and SP grades. SM-grade engine oil includes both synthetic and mineral oils, such as LIQUI MOLY oil which is API SM grade. More details are as follows: 1. The API quality grade represents the quality level of engine oil, using simple codes to describe the working capability of engine oil. In the API quality grade, engine oil is divided into the S series and C series. The S series is specialized oil for gasoline vehicle engines, with grade levels including SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, SN, and SP, while the C series is specialized oil for diesel vehicles. 2. Whether it is gasoline or diesel engine oil, as the letter in the quality grade designation moves further in the alphabet, the grade improves sequentially, with the oil quality and performance becoming more superior. 3. When selecting engine oil, in addition to the viscosity grade, the quality grade is also an important indicator. Generally, the grade recommended in the maintenance manual or for the engine model is sufficient. However, if frequently driving in congested traffic conditions, it is advisable to use a higher grade of engine oil, which is more environmentally friendly and economical. Nevertheless, vehicle owners do not necessarily need to pursue the highest grade of engine oil, as while the oil quality and performance may be relatively superior, the price will also increase accordingly.

How to Replace Coolant in a Jetta?

Jetta car coolant replacement method: Before completely replacing the coolant, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with a focus on the five-way hose. The five-way hose gets its name from having five connections to different parts, and the coolant is distributed to various sections of the car after flowing through it. If there is any coolant leakage in this part, replace the hose or re-secure the connections as needed. Drain the old coolant, then flush the liquid channels with clean water. Add water to the coolant reservoir, then continuously inject water into the reservoir so that it flows through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water draining from the reservoir will have a faint pink tint. Continue adding clean water until the drained water runs clear. Note: 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 bottle 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 purged from the cooling system. Top up the coolant to the maximum mark "MAXT" on the reservoir.

What are the reasons why the auto start-stop function cannot be used?

There are several reasons why the auto start-stop function may not be usable, including the system being turned off, conditions for activation not being met, or system malfunction. Below are the detailed explanations: System being turned off: Generally, vehicles equipped with the auto start-stop function have the system enabled by default. If it fails to start, it might be due to accidentally pressing the auto start-stop button, which turns off the system. It is necessary to check whether the system has been turned off. Conditions for activation not being met: For manual transmission vehicles, the conditions for activating the auto start-stop function are more complex. When parking, the system will only activate after recognizing three actions: "shifting to neutral, pulling the handbrake, and releasing the clutch." Different models from various brands have different designs for the auto start-stop system. Taking the New Passat's auto start-stop system as an example, it must meet certain conditions, such as fastening the seatbelt, closing the second left front door, and the engine being in the started state. It is advisable to refer to the precautions in the user manual. System malfunction: If the auto start-stop system malfunctions, or if the system fails to work due to wiring or other reasons, it is best to have it inspected and repaired at a 4S shop.
