What Level Does SP Grade Engine Oil Belong To?

1 Answers

SP grade is the highest level in the engine oil industry. Characteristics of SP Grade: SP engine oil solves the low-speed pre-ignition issue in turbocharged direct-injection engines, meaning the engine has better low-speed anti-knock performance, resulting in smoother engine operation. It enhances the lubricant's protection against wear on the engine's timing chain. Due to the higher certification standards, SP oil also possesses excellent features such as anti-wear, cleaning, and fuel efficiency. Requirements for SP Standard Engine Oil: It must contain low-SAPS (low sulfur, low phosphorus, low ash) additives, which effectively prevent excessive byproducts from oil combustion from adhering to the particulate filter, thereby reducing the likelihood of clogging.

What does the Highlander snow button mean?

The Highlander snow button refers to the vehicle's snow mode. The snow mode is achieved through an automated program that starts the car in second gear to reduce torque output during startup, ensuring a gentler and smoother power delivery to prevent wheel slippage on snowy surfaces. Additionally, during driving, the operating range of the ABS (Anti-lock Braking System) is expanded. Under normal circumstances, the ABS only engages when the brake pedal is pressed hard, but in snow mode, it activates even during non-emergency braking. All these features are designed to ensure safer driving on icy and snowy roads. The Highlander's body dimensions are 4795mm in length, 1910mm in width, and 1760mm in height, with a wheelbase of 2790mm. The vehicle features prominent fenders, black side skirts, and chrome-plated door sills, giving it a sturdy, elongated, and dynamic appearance.

Does the car charge when idling after starting?

The car can charge when idling after starting, but the prerequisite is to ensure that all electrical appliances except the engine operation are turned off. First, as long as the generator is working, it can charge the battery. The power source of the generator comes from the engine. After the car starts, the engine begins to work, and the engine transmits power to the generator through the belt, thus starting to charge the battery. It should be noted that the charging efficiency is different between idling and driving states. When the vehicle is moving, because you need to step on the accelerator, as soon as you step on the accelerator, the engine speed will increase, and accordingly, the generator will receive more power, so the generator's output will increase, and the charging amount to the battery will also be more. If the engine is idling, the generator speed is slower, and the output power will be very limited.

What are the Four Major Auto Shows in China?

The four major auto shows in China include the Shanghai Auto Show, Beijing Auto Show, Guangzhou Auto Show, and Chengdu Auto Show. Below are their detailed introductions: 1. Shanghai Auto Show: Also known as the Shanghai International Automobile Industry Exhibition, it was founded in 1985 and is held biennially. In June 2004, the Shanghai Auto Show received certification from the Global Association of the Exhibition Industry (UFI), becoming the first among China's four major auto shows to be UFI-recognized. The Shanghai Auto Show also uses its official website as a platform to introduce world-class online interactive multimedia communication and exhibition technologies, hosting the 'Online Interactive Shanghai Auto Show' and organizing the 'China Automotive Design Forum' alongside high-level forums. 2. Beijing Auto Show: Officially named the Beijing International Automotive Exhibition, the 2020 Beijing Auto Show utilized both the new and old exhibition halls of the China International Exhibition Center. The new hall primarily displays domestic and international passenger and commercial vehicles, while the old hall focuses on automotive parts and related products. Additionally, the old hall hosted the '3rd Beijing International New Energy Vehicle Exhibition,' dedicated to showcasing new energy vehicle designs and products from global manufacturers. 3. Guangzhou Auto Show: As one of the most influential of China's four major auto shows, the Guangzhou Auto Show has, since its inception in 2003, aimed to provide a high-quality, international, and comprehensive exhibition platform for the automotive industry. It has worked alongside industry elites to witness the growth and strengthening of China's automotive sector. 4. Chengdu Auto Show: As the largest and most influential auto show in China's western region, the Chengdu Auto Show has distinguished itself among numerous domestic auto shows, becoming one of the most popular and attractive automotive events. Its exhibits cover a wide range of passenger and commercial vehicles, automotive parts, aftermarket products, automotive technology displays, and automotive media.

How to Read Engine Oil Specifications?

To read engine oil specifications, look for the SAE and API markings on the oil's outer packaging. The number following SAE indicates the oil's viscosity value, while the number after API denotes the oil's quality grade. The 'W' in the grading stands for Winter, and a smaller number before the 'W' indicates better low-temperature fluidity of the oil. The number after the 'W' represents the oil's high-temperature resistance, with a higher number indicating better protective performance at high temperatures. Engine oil specifications consist of two parts: the grading and viscosity specifications, typically used to indicate viscosity and quality. SAE in the specifications is the abbreviation for the Society of Automotive Engineers, and API stands for the American Petroleum Institute.

Do Automatic Headlights Automatically Switch Between High and Low Beams?

Automatic headlights do not automatically switch between high and low beams. Generally, automatic headlights default to low beams, and the driver needs to manually adjust them to high beams when necessary. The headlights are equipped with a photosensitive control system, which is referred to as automatic headlights. When the driving environment becomes dark, the headlights will automatically turn on, and they will turn off when the light becomes brighter. Automatic headlights are particularly useful when driving through tunnels. Correct usage of high and low beams: 1. Use low beams when driving on roads with streetlights at night, encountering pedestrians on the roadside, or navigating narrow roads, narrow bridges, or curves; 2. Use high beams when driving on roads without streetlights or on long, straight roads with poor visibility at night; 3. Always switch to low beams when encountering oncoming traffic at night and switch back to high beams after passing the other vehicle.

How to Open the Trunk of a Chevrolet Car?

Methods to open the trunk of a Chevrolet car: 1. The opening switch is located below the handle of the driver's door—press it to open; 2. Some models require using the key or lifting the lever under the driver's seat; 3. For some models without an internal trunk release switch in the cabin, you can use the trunk button on the key—press and hold the trunk unlock button to release the trunk. Taking the Chevrolet Cruze as an example: Its exterior follows the family-style large grille, with angular headlights on the full front end appearing very bold. The strongly lined engine hood, combined with the integrated bumper and slightly exaggerated design, looks passionate and youthful. The Cruze is equipped with a 1.5L naturally aspirated engine and a 1.4T turbocharged engine, paired with a 6-speed manual transmission, 6-speed automatic transmission, or 7-speed dual-clutch transmission.
