What do the oil grades SP and SN mean?

1 Answers

07/29/25 9:42pm
Fully synthetic oils SP and SN are lubricant grade standards issued by the American Petroleum Institute. Here are some introductions about SP and SN grades: 1. Whether it is a gasoline or diesel vehicle, each increment in the letter indicates a higher grade of engine oil, and its performance is generally superior to the previous letter grade. SP is equivalent to SN being the next higher level. 2. SP-grade engine oil has a slightly lower phosphorus content, which can reduce wear on the three-way catalytic converter. At the same time, it generally offers stable improvements over SN-grade engine oil in terms of noise reduction, fuel consumption, and acceleration performance.

How to Set the Fuel Consumption Display on the Tiguan?

Tiguan's 100-kilometer fuel consumption display can be set using the adjustment button on the wiper switch located on the right side of the steering wheel. Press the top of the wiper switch for 2 seconds to enter the selection interface, where you can choose the fuel consumption display. The onboard computer will show two parameters: instantaneous fuel consumption and average fuel consumption. More related information is as follows: 1. Kilometer Fuel Consumption: 100-kilometer fuel consumption refers to the fuel consumption of a vehicle traveling 100 kilometers on the road at a certain speed. It is a theoretical indicator of the vehicle. The 100-kilometer fuel consumption is a value measured by the manufacturer using a dynamometer installed on the vehicle's chassis under objective conditions, converted into speed parameters, and then calculated as the theoretical experimental 100-kilometer fuel consumption data for the model. Since most vehicles approach their economical speed at 90 km/h, the publicly announced theoretical fuel consumption is usually the 100-kilometer fuel consumption at 90 km/h. The displacement is determined by analyzing the carbon content in the exhaust gas using an exhaust analyzer and the carbon balance method. 2. Tiguan Silk Road Edition: The Tiguan Silk Road Edition was mainly launched to commemorate the "Belt and Road Global Tour" event, which retraced the Silk Road. The overall design of the Tiguan Silk Road Edition is the same as the current Tiguan model, except for the "SILKROAD" logo on the side of the body to indicate its unique identity. The xenon headlights feature a polygonal design, and the LED taillights have been smoked for a distinctive look.

What is the Default Bluetooth Password for Car Systems?

The default pairing password (PIN code) for car Bluetooth is usually 0000, 1234, or 1111. You can check the user manual for confirmation. Typically, when a car owner picks up a new vehicle, the staff at the 4S dealership will inform them of the car's unique PIN code. If the owner forgets their car's Bluetooth PIN code, they can visit the 4S dealership to inquire with the staff. Generally, 4S dealerships also keep a copy of the car's Bluetooth PIN code. The car's Bluetooth PIN code is used for matching performance and car key synchronization after clearing fault codes and replacing important components. It serves as the vehicle's production identification code, ensuring the car's security. The function of car Bluetooth: Car Bluetooth can automatically identify mobile phones, enabling connection without cables or phone holders. The owner can control the phone without touching it, even keeping both hands on the steering wheel, using voice commands to answer or make calls. Users can conduct calls through the car's audio system. Effective range: Car Bluetooth uses advanced digital signal processors and language devices, suitable for any harsh environment. It eliminates background noise and echoes, ensuring high-quality call effects for both parties, with an effective distance of 10 meters. How to turn on car Bluetooth: Since car Bluetooth does not have physical on/off buttons inside the vehicle, all operations must be performed on the central control screen. Operation method: First, bring up the main menu on the central control screen, find and select the phone button in the menu. In the secondary menu of the phone, you can see the Bluetooth option. Click to turn it on. Phone cannot find car Bluetooth device: Car Bluetooth is in an invisible state: When car Bluetooth is invisible, the phone cannot detect it. Solution: Set the car Bluetooth to a discoverable state. Distance is too far: If the phone and car Bluetooth device are too far apart, the phone may fail to detect the car Bluetooth device. Solution: Bring the phone closer to the car Bluetooth device.

How to reset the tire pressure on the Trumpchi M6?

Trumpchi M6 tire pressure reset method: First, turn on the ignition switch, press and hold the tire pressure monitoring reset button until you hear a "dong" sound, then release. The tire pressure monitoring system will store the current normal tire pressure data, automatically clear the previous data, and finally, the dashboard warning light will turn off, completing the tire pressure reset. The tire pressure monitoring indicator is a yellow symbol, an irregular circle with no stamp on top and four small spikes at the bottom, containing an exclamation mark inside. The tire pressure monitoring indicator light indicates abnormal tire pressure. Abnormal tire pressure generally has the following three causes: Tire pressure abnormality: Generally, it will trigger an alarm if the pressure is below 1.8 bar or above 3.0 bar. At this time, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure reset is not performed in time, the tire pressure monitoring system will still record the previous data, causing the tire pressure monitoring indicator light to turn on. In this case, simply perform a tire pressure reset. Tire pressure sensor damage: The tire pressure sensor is used to monitor tire pressure and is directly installed inside the tire, connected to the tire inflation port. If the tire pressure sensor is damaged during driving, it will also cause the tire pressure warning light to turn on. For sensor damage issues, only replacement with a new component is possible.
