How to Choose Engine Oil for Vehicle Maintenance?

1 Answers

Methods for selecting engine oil during vehicle maintenance are as follows: 1. Choose according to usage regulations: The appropriate engine oil type and usage grade should be selected based on the working conditions of the car engine. 2. Select based on regional seasonal temperatures: The choice of engine oil should consider the regional seasonal temperatures, combined with the engine's performance and technical condition, to select the appropriate oil grade and viscosity level. 3. Choose the right viscosity: The viscosity of the engine oil should be as low as possible, but it must be determined based on local temperatures and the vehicle's grade. For mid-to-high-end cars, engine oil must be selected according to the manufacturer's guidelines and should not be chosen arbitrarily. 4. Gasoline engine oil cannot be used in diesel engines: Special gasoline engine oil should not be used as a substitute for diesel engine oil to avoid accelerating wear in diesel engines. In principle, gasoline engine oil and diesel engine oil should be used separately.

What is the D gear?

D gear is the drive gear, a common gear in automatic transmission models, usually located in the middle-rear position of the gear shift console, behind the N gear, designed to enable the car to automatically select gears while moving forward. The D gear covers all forward gears in the car's automatic transmission. When the gear shift lever is placed in the D gear, the hydraulic control system will automatically engage the corresponding forward gear based on the throttle opening signal and vehicle speed signal. Automatic transmission generally refers to the car's automatic gear-shifting mechanism, where the control system of the automatic transmission automatically selects the appropriate gear based on the engine speed and load during driving, replacing the driver's subjective judgment of timing and gear-shifting operations.

How to Display Tire Pressure Values on the Tenth-Generation Accord?

Tire pressure values represent the air pressure of the four tires, with bar being the most commonly used unit for tire pressure. Below is a detailed introduction to tire pressure monitoring: Direct Tire Pressure Monitoring: Direct tire pressure monitoring systems use pressure sensors installed in each tire to directly measure the tire's air pressure. The pressure information is then transmitted wirelessly from inside the tire to a central receiver module, which displays the tire pressure data for each tire. Indirect Tire Pressure Monitoring: When the air pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the differences in rotation speeds between the tires, the system monitors the tire pressure.
