Engine oil should be replaced when its remaining life is below 20%. Precautions for selecting engine oil: Criteria for selecting engine oil: Choose oil that matches your engine model, preferably multi-grade oil. Multi-grade oil offers advantages such as fuel efficiency, long service life, and high performance, providing excellent protection for the engine. Select oil according to your engine's requirements. Avoid using higher-grade oil in lower-performance engines or lower-grade oil in high-performance engines. Oil level should be below the dipstick mark: The oil level should be slightly below the mark on the car's dipstick. Do not overfill. Choose oil with different viscosity based on your vehicle's engine operating conditions. Do not mix different engine oils: If switching from premium to regular oil, first drain the existing oil completely and clean the lubrication system thoroughly. Never mix different types of oil.

How to Turn Off the Daytime Running Lights on a Civic?

It is not possible to turn off the daytime running lights while the car is in motion. They will only turn off after the engine is shut off and the car is locked. Here’s how to operate the Civic's lights: 1. Turn signals: Push the light control lever downward to activate the left turn signal, and upward for the right turn signal. 2. Automatic headlights: Rotate the outermost ring on the light control lever to the AUTO position to turn on the automatic headlights. 3. Parking lights: Rotate the outermost ring to the parking light position to activate them. 4. Low beam headlights: Rotate the outermost ring to the low beam position to turn them on. 5. Rear fog lights: Rotate the inner ring on the light control lever to the REAR position to activate the rear fog lights. 6. Front fog lights: Rotate the inner ring to the front fog light position to turn them on.

What to Do When the Engine Suddenly Stalls While Driving?

Here are the steps to handle a sudden engine stall while driving: 1. Avoid braking randomly before pulling over to the side, as this may waste the potential inertial energy that could be used to coast and park the vehicle. 2. If the vehicle stalls and restarting fails, immediately turn on the right turn signal, use the inertia to slowly guide the vehicle to the roadside, turn on the hazard warning lights, and check the cause of the stall to troubleshoot the issue. Below are the handling methods for stalling under different conditions: 1. Stalling while waiting at a stop. Restart the engine. For automatic transmission models, shift the gear to P (Park) or N (Neutral) before restarting the engine. 2. Stalling while coasting. First, stabilize the steering wheel, apply intermittent braking as needed, depress the clutch for manual transmission cars, shift the gear lever to the appropriate gear based on the speed, then release the clutch to use the vehicle's speed to restart the engine, similar to push-starting. For automatic transmission cars, shift the gear to Neutral first, being careful not to mistakenly shift to R (Reverse), as this could damage the transmission, then restart the engine. 3. Stalling while braking. First, stabilize the steering wheel, increase braking force, and observe the surroundings. If possible, change lanes to avoid obstacles ahead, but apply more force when turning the steering wheel, as the lack of power steering will make steering heavier.

How to Extract Oil from a Car?

There are four methods to drain oil from a car: 1. Open the oil drain screw of the fuel tank; 2. Insert a tube into the fuel filler port to siphon the oil. When inserting the tube, use a stick to push open the valve inside the filler port to facilitate smooth insertion of the tube; 3. Disconnect the engine's return oil pipe, and collect the oil while the engine is running. Be careful not to let the oil splash, especially onto the ignition system. Note that this method is not feasible for a small number of vehicles that do not have a return oil pipe; 4. Collect oil from the engine's intake oil pipe; remove the intake oil pipe, locate the fuel pump relay, and use wires to bridge the fuel pump relay to activate the fuel pump, thereby completing the oil drainage task.

What are the differences between metallic paint and non-metallic paint for cars?

The differences between metallic paint and non-metallic paint for cars are as follows: 1. Metallic paint has higher hardness: Metallic paint is harder than non-metallic paint, which is one of the reasons many car owners choose metallic paint when selecting car paint. Greater hardness means metallic paint has stronger wear resistance, allowing it to resist minor scratches to some extent, thereby reducing car maintenance costs. 2. Metallic paint offers more color options: Non-metallic paints have fewer color choices, typically common colors like red or black, which lack novelty. Metallic paint can provide a wide range of colors, and custom colors can be mixed according to customer preferences. Additionally, metallic paint has an advantage in brightness. 3. Price difference: The manufacturing cost of metallic paint is higher than that of regular paint. Metallic paint contains metal powder, which enhances the paint's effect, naturally resulting in a higher price.

What does off mean on the car?

OFF in a car means off, and ON means on. The off light on the car mainly refers to ESP-OFF. ESP stands for the Electronic Stability Program, which is an active safety device mainly used to prevent the risk of vehicle skidding and fishtailing. If the ESP-OFF light on the car dashboard lights up, it means that the vehicle's Electronic Stability Program is turned off or has malfunctioned. More detailed information is as follows: 1. If you accidentally press the ESP-OFF button on the vehicle, you can press it again briefly to turn the ESP back on. If the ESP-OFF light is on due to a system malfunction, then the vehicle should be sent to a 4S shop for repair in time. There are many reasons that can cause the malfunction light to come on, such as circuit failure, sensor damage, electronic control unit signal error, or battery power loss. 2. ESP is particularly sensitive to oversteer or understeer. For example, when the car oversteers (turns too sharply) while turning left on a slippery road, it will fishtail to the right. The sensor will sense the skid and quickly brake the right front wheel to restore traction, generating an opposite torque to keep the car in the original lane. The difference between a car with ESP and one with only ABS and ASR is that ABS and ASR can only react passively, while ESP can detect and analyze the vehicle condition and correct driving errors, preventing problems before they occur.
