The low beam model of the Refine M4 is h7, and the high beam model is h1. When replacing the bulb, it is necessary to turn off the headlight switch in time to allow the bulb to cool down. When installing a new bulb, do not touch it directly with your hands. Relevant information about car headlights is as follows: 1. Car headlights, also known as car front lights or car LED daytime running lights, as the eyes of the car, are not only related to the external image of the owner but also closely connected to safe driving at night or in bad weather conditions. 2. Car headlights include the following 8 types: LED lights, signal lights, halogen lights, width indicator lights, HID xenon lights, left and right turn signals, xenon lights, and fog lights.

I've been driving the Refine M4 for many years. The headlight model of this car is usually H7, used for both high beam and low beam. It's easy to find compatible bulbs with the standard configuration. When replacing them yourself, pay attention to minor variations across different model years. For example, some 2018 models use H1, but it's rare. I recommend checking the vehicle's user manual or calling the 4S store to confirm the model first. Using the wrong bulb type may cause flickering or poor vibration resistance. Regularly checking if the headlights are working is also crucial. If they fail, replacing them promptly can prevent hazards during night driving. I once experienced poor visibility in the rain due to weak lighting. Actually, replacing ordinary halogen bulbs like H7 is simple and inexpensive, but you need to remove the front lamp cover. Beginners should avoid forcing it to prevent damaging parts.

I'm a car novice who just got a Refine M4. After checking online, I found that H7 is the mainstream bulb model for headlights. Owner forums indicate that post-2019 models are basically the same. You can directly search for 'Refine M4 bulb' on JD.com or Taobao—H7 bulbs usually cost less than 30 yuan each. Changing bulbs is quite beginner-friendly; just unscrew the lamp socket cover to operate, but remember to disconnect the power to avoid electric shock. If you're unsure about the model, take a photo of the headlight and ask customer service. A quick reminder: headlight quality affects nighttime safety, especially on mountain roads or highways—don't compromise. My car struggled in foggy conditions due to aging bulbs, but after replacement, visibility improved significantly. Regularly check and clean the lens to prevent dust buildup, as it can halve brightness.

Having worked in the auto industry for years, the Jianghuai Refine M4 mostly uses H7 bulbs for its headlights, suitable for most versions like the business or family models. Before replacing, check the bulb socket. The H7 features a single-filament design with strong versatility, and upgrading to H7-compatible LED or xenon bulbs is easy but requires adjusting the beam height to avoid glare. Specifications may vary by year—for instance, some 2020 high-end models use different specs. It's best to remove the old bulb to check its label or consult a professional mechanic to avoid mistakes. Choosing the right headlight bulb can last up to a year and a half, saving you from frequent replacements and waste. Keep the wiring dry, as rainwater in the socket can corrode connections, leading to flickering or poor contact. Fix issues promptly to prevent more costly repairs later.

Is Synthetic Oil the Same as Full Synthetic Oil?

Synthetic oil is not the same as full synthetic oil. Synthetic oil is divided into semi-synthetic oil and full synthetic oil. Strictly speaking, full synthetic oil refers to high-quality oil products made 100% from polyolefins or artificially synthesized esters, usually labeled with the word "synthetic" on the oil container. Semi-synthetic oil is made from semi-synthetic base oil, which is lubricant formulated from Group III base oils internationally. It is a product purified from mineral oil through hydrocracking technology. Compared to semi-synthetic oil, full synthetic oil has the following characteristics: 1. Better high and low-temperature performance; 2. Longer oil change intervals; 3. Suitable for more severe driving conditions.

What is the shelf life of fully synthetic engine oil?

Fully synthetic engine oil has a shelf life of 5 years, with some oils lasting up to 12 years. Generally, oils within 3 years should have no issues at all. If the container is opened, it should be used as quickly as possible; otherwise, the oil may deteriorate and its lubricating properties may decline. When not in use, it must be stored sealed to achieve the best possible performance. Synthetic engine oil is manufactured using chemical synthesis methods, and depending on the intended use, various components can be adjusted. Advantages of fully synthetic engine oil: 1. Smoother cold starts; 2. Longer oil change intervals, equivalent to 1.5 times that of conventional lubricants; 3. Extends engine life and reduces maintenance frequency.

What are the functions of fully synthetic engine oil?

Fully synthetic engine oil has the following functions: 1. Lubrication to reduce wear - There is rapid relative sliding between the piston and cylinder of the engine, as well as between the main shaft and bearing shells. The oil forms a sufficiently thick oil film between the two sliding surfaces to separate the relatively sliding parts and reduce wear; 2. Cooling - The oil can bring heat back to the oil tank and then dissipate it into the air to help the radiator cool the engine; 3. Cleaning - The oil can circulate carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank, flushing away dirt generated on the working surfaces of parts through the flow of the lubricating oil; 4. Shock absorption - When the pressure at the engine cylinder port rises sharply, suddenly increasing the load on the piston, piston chips, connecting rod, and crankshaft bearings, the load is transmitted through the bearings for lubrication, cushioning the impact load.

What Happens When the Air Filter Gets Dirty?

When the air filter is dirty, it can lead to insufficient air intake, incomplete fuel combustion, unstable engine operation, and symptoms such as a muffled engine sound when continuously pressing the accelerator pedal, sluggish acceleration response, weak operation, and thick, black exhaust emissions. Below are specific details about the air filter: 1. Function: The car air filter is installed in front of the carburetor or intake pipe to filter the air entering the engine. During operation, the engine draws in a large amount of air, which contains many dust particles. Without filtration by the air filter, this can accelerate wear on the piston group and cylinder. The car air filter serves to remove dust and particulate matter from the air, ensuring that sufficient clean and dry air enters the cylinder. 2. How to Determine if It's Dirty: You can check the surface color of the air filter. If the filter paper remains gray-black after cleaning the surface dust, it indicates that the filter paper can no longer be used and should be replaced immediately.

How to Replace Spark Plugs?

Steps to replace spark plugs: Open the hood, lift the plastic cover of the engine, remove the high-voltage ignition wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing, check for external debris like leaves or dust and ensure they are cleaned thoroughly. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the high-voltage ignition wires in the correct firing order and secure the cover. How to determine if spark plugs need replacement: Remove the spark plug and inspect its appearance. A normal spark plug's insulator skirt and electrodes should appear grayish-white, grayish-yellow, or light brown. A properly functioning spark plug has a reddish-brown insulator skirt, with an electrode gap between 0.8-0.9mm and no signs of electrode damage. If the spark plug is covered in oil or deposits but not damaged, it can be cleaned and reused. If the spark plug is severely damaged—showing signs of blistering, black streaks, cracks, or melted electrodes—identify the cause of the damage, fix the issue, and replace the spark plug. Additionally, if the spark plug appears blackened as if smoked, it indicates an incorrect heat range selection, a rich fuel mixture, or oil leakage.
