What else needs to be replaced when changing the engine oil?

If the navigation doesn't report speed detection, does it mean there's no speeding?

No, the navigation can only remind you whether there is speed detection ahead. You need to judge whether you are speeding by yourself. The following is a related introduction to car navigation: 1. Components: The car GPS navigation system consists of two parts. One part is composed of the GPS receiver and display device installed in the car; the other part is composed of the computer control center, and the two parts are connected via positioning satellites. 2. Working principle: In GPS observation, the distance from the satellite to the receiver can be obtained. Using the distance formula in three-dimensional coordinates and three satellites, three equations can be formed to solve the position of the observation point. Considering the error between the satellite clock and the receiver clock, there are actually four unknowns: X, Y, Z, and clock difference. Therefore, a fourth satellite needs to be introduced to form four equations for solving, thereby obtaining the longitude, latitude, and elevation of the observation point.

What is the original engine oil specification for the Sail 3?

The official manual for the Sail 3 recommends using engine oil with a specification of 5W-30. It is advised to use fully synthetic oil of SM or SN grade. For subsequent maintenance and oil changes, you may choose brands such as Mobil, Shell, Castrol, or Total. The viscosity of engine oil varies with temperature changes, so special attention should be paid to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand low temperatures down to -30°C. The smaller this number, the better the low-temperature fluidity, resulting in smoother cold starts for the vehicle. The latter number represents the kinematic viscosity of the oil at 100°C. A higher value indicates better ability to maintain viscosity under high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil in the Sail 3 is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan to catch the old oil until no more oil flows out. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain; Use a specialized wrench to remove the oil filter; Apply oil to the seal of the new oil filter and tighten it clockwise by hand; Add the new engine oil through the oil filler cap on the engine valve cover, typically filling about three-quarters of the oil container; Start the engine and let it run for 5 minutes, then check for any oil leaks around the drain plug and oil filter. If leaks are found, repairs should be made; After stopping the engine, pull out the oil dipstick to check that the engine oil level is within the standard range.

Is driving once a week considered long-term inactivity?

Driving once a week is not considered long-term inactivity. You can start the vehicle for 5-10 minutes every one or two weeks to recharge the battery. The effects of long-term inactivity are as follows: 1. During long-term parking: Continuous battery discharge can easily lead to battery depletion, which may mildly affect the next vehicle start or, in severe cases, directly cause battery damage. Each instance of excessive discharge causes irreversible harm to the battery. 2. Rubber components in the car: Such as tires and door/window seals, are prone to premature aging due to sunlight and humidity changes, leading to degraded performance and shortened lifespan. The aging of rubber components is mainly because rubber is an unsaturated hydrocarbon polymer that easily absorbs oxygen from the air and oxidizes. Additionally, vulcanized rubber has some permeability, allowing oxygen to enter and cause oxidation. 3. Tires: Tires are prone to localized deformation due to prolonged parking.

What is the difference between DSS transmission and AT transmission?

Introduction to the differences between DSS transmission and AT transmission: 1. Different meanings: DSS transmission is a dual-clutch transmission, while AT transmission generally refers to an automatic transmission. 2. Different compositions: Manual transmissions mainly consist of gears and shafts, achieving speed and torque changes through different gear combinations. Automatic transmissions (AT) are composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque changes through hydraulic transmission and gear combinations. Maintenance methods for automatic transmissions: 1. Power transmission requires adding transmission oil as specified: Do not opt for cheaper or more convenient manual transmission oil, as this can cause severe burning of clutches and brakes. 2. In addition to adding the specified oil: It is also necessary to use the correct type of transmission oil, otherwise issues like clutch slippage and hot gear jumping may occur. 3. The addition of automatic transmission fluid (ATF) must be strictly controlled: The ATF level must be between the bottom of the planetary gears and the top of the control valve body. If the fluid level is too high, the planetary gears' agitation can cause the ATF to foam, leading to oil leakage during driving. If the fluid level is too low, clutches and brakes are prone to slippage.
