The Elantra uses 5W40 oil. Below is an introduction to the functions of engine oil: 1. Lubrication: There is rapid relative sliding between the piston and cylinder, and between the main shaft and bearing. To prevent excessive wear of parts, an oil film of sufficient thickness needs to be established between the sliding surfaces to separate them, reducing wear and extending mechanical life. 2. Sealing: Engine oil can form a seal between the piston rings and the piston, reducing gas leakage and the entry of pollutants. 3. Cleaning: Engine oil can circulate and carry away carbon deposits, sludge, and worn particles from engine components back to the oil pan. 4. Cooling: Engine oil can circulate and dissipate some of the heat from the engine.

How to Restore a Worn Steering Wheel?

First, use a small amount of cleaner to wash the affected area. Spray the cleaning solution onto the dirty spots, then scrub with a scouring pad, followed by further cleaning with a clean towel. Finally, apply a leather protectant with a sponge for polishing. If the steering wheel is covered with a fur or leather wrap, you can remove it first for separate treatment. Cleaning the steering wheel is essential as it is frequently touched by hands and can easily become dirty. If it feels sticky, it may affect driving comfort. Simply wiping it with water is usually sufficient for cleaning. Adding a bit of cleaner can make it easier to remove stains, but be sure to wipe it clean with water afterward.

Manual Transmission: Brake First or Clutch First?

Manual transmission vehicles require pressing the clutch first when stopping. Below is relevant information about manual transmissions: 1. Introduction: A manual transmission is a gear-shifting device used to alter the engine's rotational speed and torque transmitted to the drive wheels. It enables vehicles to obtain different traction forces and speeds under various conditions such as stationary starts, hill climbing, turning, and acceleration, while keeping the engine operating within favorable working ranges. 2. Classification and Structure: Manual transmissions consist of gear transmission mechanisms, transmission housing, and control mechanisms. The gear transmission mechanisms can be classified by the number of forward gears or the form of shafts. Based on forward gears, they can be categorized as three-speed, four-speed, five-speed, or multi-speed transmissions; according to shaft forms, they can be divided into fixed-shaft and rotating-shaft types.

What Causes an Automatic Transmission Vehicle to Suddenly Stall While Driving?

Automatic transmission vehicles may suddenly stall while driving due to battery issues, high-voltage circuit faults, or engine fuel line blockages. Battery Issues: When a battery reaches the end of its lifespan, its capacity and output voltage decrease. This can directly cause starter malfunctions, insufficient voltage, and failure of the engine spark plugs to generate sparks. In severe cases, the engine may stall and become difficult to restart. Solution: Replace the battery. High-Voltage Circuit Faults: Inspect the high-voltage circuits for signs of aging, detachment, short circuits, or open circuits. Engine Fuel Line Blockages: Irregular fuel supply can interrupt the engine's stroke, or severe carbon buildup or erosion in the spark plugs can cause unstable ignition, leading to difficulty starting the engine and abnormal stalling when the throttle changes. Solution: Perform regular cleaning and maintenance of the engine's fuel lines (including both fuel supply and lubrication lines), promptly inspect and replace spark plugs, and if necessary, conduct a carbon removal treatment inside the cylinders.
