What is the best engine oil for Geely Boyue?

Geely Boyue uses 5W-40 engine oil, and the official recommendation is Shell semi-synthetic oil. Below are detailed specifications for engine oil usage in Geely Boyue: 1. Currently, Geely Boyue is equipped with two powertrains: JLD-4G20 and JLE-4G18TD. 2. For JLD-4G20 engine: SAE5W-30 oil; API quality grade: SL or higher. For JLE-4G18TD engine: SAE5W-40 oil; API quality grade: SN or higher. 3. Taking 0W-20 as an example: The "0W" in 0W-20 indicates the cold-start performance of the oil. Oil with a lower number before the W can start the engine more easily in cold weather. The "20" indicates the oil's viscosity characteristics at high temperatures. 3. High-viscosity oils (with higher values) may be more suitable for high-speed driving or heavy-load vehicles. If SAE 10W-30 or higher viscosity oil is used in cold weather, the engine may be difficult to start. 4. It is recommended to use SAE 0W-20, 5W-20, or 5W-30 engine oil. Relatively speaking, using 0W-20 oil can maximize fuel savings.

What are the effects of not changing engine oil for a long time?

If engine oil is not changed for a long time, it will cause the following effects: 1. As the oil's lifespan declines, its lubricating ability will also rapidly decrease, preventing the engine from receiving proper lubrication, leading to abnormal wear. 2. Metal debris cleaned by the oil cannot be expelled and will accumulate inside the engine, causing dirt to form a large amount of sludge. 3. The engine may also experience increased fuel consumption, reduced power, difficulty starting, abnormal shaking, and poor operation. Below are the functions of engine oil: 1. Lubrication: There are many moving friction surfaces inside the engine (e.g., piston and cylinder, crankshaft and crankshaft bearing, valve and valve guide, etc.). The role of engine oil is to establish an oil film between these friction surfaces to achieve lubrication and anti-wear effects. 2. Cleaning: The movement of engine components causes wear and produces metal debris. Engine oil continuously circulates inside the engine through the action of the oil pump and carries these metal debris back to the oil pan. 3. Cooling: The continuous circulation of engine oil inside the engine can carry away the heat generated by the engine and cool it through the oil cooler. (The cooling effect of engine oil is only auxiliary.) 4. Sealing: The oil film formed by engine oil on the surface of the engine cylinder wall and the inner surface of the valve guide can provide a sealing and leak-proof effect.

What causes the ABS light to illuminate on the dashboard?

ABS light illumination can occur in various states, with different causes and solutions for each state. The details are as follows: State 1: ABS warning light stays on constantly (most common). Cause 1: The ABS speed sensor's sensing part is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. This prevents the ABS computer from determining the vehicle's speed or the wheel's slip rate, thus failing to issue appropriate commands to regulate braking. Solution: Clean the dirt from the speed sensor and adjust the gap between the sensor and the signal ring to restore normal function. Cause 2: Poor signal transmission due to loose connections in the system wiring or poor contact in the ABS relay, leading to system failure. Solution: Check the wiring connections and reconnect any loose parts. State 2: ABS warning light intermittently illuminates but turns off when accelerating. Cause: When multiple electrical devices are in use, the battery voltage drops below 10.5V. The ABS light turns off as the engine speed increases and voltage rises. This may also occur if the ABS system's power supply voltage is too low due to poor terminal contact or grounding issues. Solution: Check the battery's specific gravity, inspect the charging system, and examine the power supply (e.g., voltage relay or poor power contact). State 3: ABS warning light stays on after engine start and only turns off when the engine is turned off (IGFF). Cause: Poor grounding contact in the ABS hydraulic valve body; poor contact in the ABS hydraulic valve body's wiring connector; ABS computer malfunction. Solution: Loosen and retighten the grounding screw of the hydraulic valve body, cleaning the contact surface if necessary. Check if the connector gap has widened. Replace the ABS or ABS/ASR computer if needed. State 4: ABS warning light illuminates during high-speed driving. Cause: During high-speed driving, the ABS computer detects a significant discrepancy between the rear and front wheel speed signals. This may also occur due to incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the label near the fuel tank cap. State 5: ABS warning light intermittently illuminates. Cause: Improper adjustment of the brake light switch; poor internal contact in the brake light. Solution: With the engine running, press the brake pedal and use a finger to push the brake switch linkage all the way down. Release the brake pedal to complete the self-setting position. Replace the brake light switch if necessary. If the ABS warning light is on, it is advisable not to continue driving. An illuminated ABS light indicates a malfunction in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may skid uncontrollably, making it difficult for the driver to slow down or adjust the vehicle's trajectory, posing significant safety risks.

What is the solution for vehicle CO failure?

Vehicle CO failure solutions are as follows: 1. Replace spark plugs. Both new and old ones are acceptable, as long as the electrode points are cleaned with sandpaper and the gap is properly adjusted. 2. Adjust ignition timing. Delaying the ignition timing will significantly reduce CO content in the exhaust. Since the ignition time is delayed, the combustion time in the combustion chamber will be shortened, the maximum combustion temperature will decrease, and the emissions of hydrocarbons and nitrogen oxides will be reduced. 3. Clean the distributor contacts and distributor rotor contacts. 4. Clean the three-way catalytic converter and oxygen sensor. 5. Add half a tank of E10 ethanol gasoline. Ethanol has a high oxygen content, which aids combustion.
