Why does the engine light turn yellow while driving?

When the engine light turns yellow while driving, it is due to poor gasoline quality, oxygen sensor malfunction, air flow sensor failure, spark plug carbon buildup, engine knocking, water temperature sensor damage, or engine misfire. Solutions for the yellow engine light on the car dashboard: Replace with compatible gasoline, replace the oxygen sensor, air flow sensor, engine, water temperature sensor, and clean the spark plugs. Functions of indicators on the car dashboard: The engine warning light indicates engine malfunction, the battery light indicates depleted battery or alternator failure, the oil warning light indicates low oil level, and the water temperature warning light indicates overheating.

What is the concept of SL-grade engine oil?

SL-grade engine oil is considered a lower-tier classification among commonly used quality grades of engine oil. The functions of SL-grade engine oil are as follows: Anti-friction: When the engine is running, the oil forms a thin film on the surfaces of various components inside the engine, preventing direct contact and friction between these parts. Cleaning: This refers to the removal of carbon deposits, oil stains, and other contaminants generated during combustion, either by dissolving them in the oil or filtering them out using an oil filter. Engine oil cleans the engine and removes residual impurities from the filter, protecting metal surfaces from corrosion caused by acids formed during combustion. Additionally, engine oil carries away combustion residues (carbon deposits), combustion by-products of the lubricant, or oxidation products (low-temperature sludge), quickly settling them to the bottom of the oil pan.

What to Do When a Car Skids on Snow?

When driving on snow, adopt a gentle approach to avoid skidding and refrain from abrupt actions. Here are some useful tips for handling car skids: Preventing Skidding While Going Uphill: For front-wheel-drive cars, pull the handbrake during the ascent to prevent rolling back and rear-end collisions. Then, engage first gear (or second gear if the car has sufficient low-end torque), lightly press the accelerator while partially engaging the clutch until you feel the tires gain traction, then release the handbrake. Many high-end cars feature a snow mode—activate this mode when driving in snowy conditions. Handling Skidding While Driving: First, avoid sudden acceleration or braking while driving. If the car skids during acceleration, ease off the throttle; if it skids during braking, release the brake pedal.

How to Deal with Engine Piston Slap?

When piston slap occurs mildly, the engine power becomes slightly unstable, the engine shakes severely, and it may cause the engine to overheat and emit black smoke. The solutions for engine piston slap are as follows: If there is a knocking sound when the engine starts and runs at low temperatures, but the sound disappears when the temperature normalizes, it can be temporarily ignored, and the engine can continue to run. If there is a noticeable knocking sound when the engine is at normal temperature, high-speed operation should be avoided as much as possible, and the engine should be disassembled for repair as soon as possible. If the cylinder is severely out-of-round or scratched, or if the gap between the piston and cylinder is too large, replacement is necessary. If the connecting rod is found to be deformed, it should be replaced if possible.

How to Use ETC for Trucks?

Even if a truck is equipped with an ETC card, it still needs to use the dedicated truck lane because it requires weighing. After weighing, use the ETC card to pay or record the charge at the toll window. ETC Usage Notes: The ETC transaction sensing range is 8 meters. When encountering a vehicle in front that has stopped, to prevent the vehicle ahead from having a faulty ETC device or no ETC device at all, maintain a distance of more than 10 meters to avoid automatic sensing and paying for the vehicle ahead. Unauthorized disassembly or movement of the OBU device, or if the ETC electronic tag falls off or becomes loose, will cause the electronic tag to fail. It can be taken to the bank where the ETC card was issued or the highway service office for inspection. If the loosening or detachment is not due to human factors, it only needs to be reactivated. When using a debit card linked to ETC, insufficient balance will also result in a failed deduction. Follow the guidance of on-site staff to use the manual MTC lane and pass by cash or card payment.

How to Read the Vehicle Temperature Gauge?

Automobile water temperature gauges are marked with the two English letters "C" and "H", or distinguished by white and red zones. "C" is the first letter of the English word "cool", meaning cold. "H" is the first letter of the English word "hot", meaning heat. Relevant information about the automobile water temperature gauge is as follows: Introduction: The water temperature refers to the temperature of the coolant. After the engine warms up, it generally displays 70-90 degrees as normal. When the water in the cooling tank is low, the water temperature will rise, and it is necessary to add water at this time. If the temperature gauge approaches the "H" or the red danger zone, and in severe cases, the water temperature warning light comes on, it indicates that the engine coolant temperature is too high. Working Principle of the Water Temperature Gauge: The sensor of the water temperature gauge is a thermistor-type sensor. It is fixed with threads on the engine cooling water passage. The thermistor determines the magnitude of the current flowing through the coil winding of the water temperature gauge.
