What is the grade of Harley transmission oil?

Harley transmission oil is generally SAE90. Hazards of not changing transmission oil: 1. Damage to the transmission's shift control mechanism; 2. Abnormal wear of gears and clutch plates inside the transmission; 3. Affects the normal operation of the transmission, leading to damage of the transmission valve body. Transmission oil and engine oil are different. Although both serve a lubricating function, their roles are distinct and should not be confused. Difference: Engine oil is a lubricant for the engine system, possessing certain properties like oxidation resistance, anti-wear, and anti-corrosion. Transmission oil, on the other hand, is primarily used to keep the gear system clean and extend the service life of internal transmission components. Due to the different structures and operating environments of the transmission and the engine, transmission oil cannot be used as engine oil, nor can engine oil be used as transmission oil.

What are the methods for changing brake fluid?

Methods for changing brake fluid include using a vacuum oil extractor to remove the old brake fluid and then adding new fluid, or using a brake fluid changer for replacement. Effects of long-term non-replacement: If not replaced for a long time, brake fluid can corrode the braking system, posing significant safety hazards; the boiling point of brake fluid decreases after absorbing moisture, which can easily lead to insufficient braking pressure and affect braking performance; deposits and impurities in the brake lines can cause brake system malfunctions and impair braking efficiency. Functions of brake fluid: It effectively lubricates the moving parts of the braking system, extending the service life of brake calipers and seals; it adapts to various environments, ensuring the flexible transmission of braking force under conditions such as high temperatures, extreme cold, high speed, and humidity.

What is the shear value of Castrol Edge 5w30?

Castrol Edge 5w30 shear value is 11.84. Lubricant high-temperature shear value: The high-temperature shear value of lubricating oil is HTHS, which refers to the oil film strength of the lubricating oil under high shear conditions at 150 degrees Celsius. The higher the value, the greater the strength. When the engine is running, the oil film is less likely to break, providing better protection for the engine. Typically, full synthetic oils require this value to be greater than 3.5. Introduction to Castrol Edge: Edge is claimed to be the most powerful oil in Castrol's product line. Castrol Edge uses advanced Titanium Fluid Technology, which makes the oil harder under extreme pressure, reducing friction and metal separation. When the pressure decreases, the oil returns to its free-flowing state.

What is the screen in front of the steering wheel called?

The platform in front of the steering wheel is called the center console. Introduction to the center console: The platform in front of the steering wheel is called the center console, which integrates air conditioning vents, a central control screen, and many functional buttons. The vehicle's center console is very important as it incorporates numerous functions. Center console design: The design of the center console is equally important. Some vehicles feature a highly futuristic design for the center console, while others emphasize a sporty feel. Some center consoles may not be as aesthetically pleasing but focus more on practicality. Designers must consider many factors when designing the center console, as it houses numerous functional buttons that need to be operated while driving. A well-designed center console allows the driver to operate these functions without compromising driving safety, whereas a poorly designed one may reduce operational convenience or even affect driving safety.

Which Consumes More Fuel: Idling or Normal Driving?

Idling consumes more fuel than normal driving. Concept of Idling: When the engine is running without load, it is called idling. During engine operation, if the accelerator pedal is completely released, the engine enters an idling state. The idle speed of the engine can be adjusted by modifying the throttle opening size. When the accelerator pedal is released while the engine is running, the engine will be in an idling state. The idle speed should not fluctuate excessively, as this can cause wear and tear on the engine. Idling State: In the idling state, it is necessary to maintain the engine speed to prevent stalling. Typically, the idle speed for a car is set at 800 rpm, which means the engine injects fuel 1600 times per minute.

Should I Claim Insurance or Pay Out of Pocket for New Car Paint Touch-Up?

New car paint touch-ups require out-of-pocket payment. Toothpaste: Toothpaste inherently has polishing properties, equivalent to applying a layer of wax, thus providing a good repair effect. However, toothpaste can only repair minor scratches. Touch-up pen: Using a touch-up pen can cover some small and faint scratches, making them less noticeable. There is a certain gap compared to the original factory paint, with color differences. The touch-up pen can only perform localized paint repairs. Car paint scratch repair agent: The repair agent has polishing properties and can quickly repair the damaged part of the car paint, fixing minor scratches.
