Different pour points: The pour point of 15w40 oil is around minus twenty-five degrees Celsius; whereas the pour point of 20w50 oil is around minus nineteen degrees Celsius. The functions of engine oil include: 1. Reducing friction and high temperatures; 2. Cooling and temperature reduction; 3. Cleaning and purification; 4. Shock absorption and cushioning; 5. Rust and corrosion prevention. Engine oil, also known as motor lubricant, consists of base oil and additives.

What Causes Stiffness in Electric Power Steering?

The reasons for stiffness in electric power steering are as follows: 1. Incorrect toe-in value of the tires: If the car makes abnormal noises when turning while driving, it indicates that the toe-in value of the tires is incorrect, causing the front wheels to be misaligned and resulting in tire wear and stiffness. In this case, the toe-in value should be readjusted or a four-wheel alignment should be performed to ensure the tires are parallel. 2. Lack of lubrication: If the car makes abnormal noises and shows obvious stiffness when turning while stationary, it indicates that the internal components of the steering gear are scraping against each other. In this case, the steering gear should be disassembled and relubricated to ensure smooth operation of the internal components.
