Which engine oil is best for Sylphy maintenance?

Sylphy's original engine oil model is 5W30. According to the official maintenance recommendations, 5W30 oil of SL grade or above should be used. The viscosity of engine oil changes with temperature, 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, where 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, ensuring smoother cold starts for the car. The latter number represents the oil's kinematic viscosity at 100°C. A higher value means the oil can maintain its viscosity index better at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the oil in a Sylphy 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 underneath to catch the old oil until it stops flowing; start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain out; use a special wrench to remove the oil filter; apply some oil to the seal of the new oil filter and tighten it clockwise by hand; add the new oil through the oil filler cap on the engine valve cover, usually filling about three-quarters of the oil container; start the engine and let it run for 5 minutes, checking for any leaks around the oil drain plug and oil filter, and repair if necessary; after stopping the engine, pull out the oil dipstick to check that the engine oil level is within the standard range.

At what tire pressure should a car not be driven?

Tire pressure should not be lower than 1.2 bar. Hazards of over-inflated tires: Reduced friction and adhesion of the tire, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates localized wear of the tread center pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overextends the tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; decreases puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, causing internal cracks or blowouts. Hazards of under-inflated tires: Increases friction with the road surface, raising fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement of tire components, causing abnormal heat due to excessive rolling; reduces the functionality of cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing abnormal wear; multiplies friction with the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing strength. High-speed driving may result in blowouts; increases tire body deformation, making the sidewalls prone to cracking and causing flexing movements that lead to excessive heat, accelerating rubber aging, cord fatigue, and breakage, while also increasing the tire's contact area and accelerating shoulder wear.

What should be paid attention to after picking up a new car?

After picking up a new car, the following aspects should be noted: 1. Small flaws in the car body paint can only be detected under sufficient light, so it is best to pick up the car in bright sunlight. Some 4S stores may have customers inspect the car indoors, but garages often have poor lighting, so be sure to move the car to a well-lit area for inspection. 2. Pay special attention to the gaps between the bumper and the car body, the door gaps, and the gaps between the front and rear bumpers. Open the doors to check if there is any color difference between the interior and exterior paint. Observe at an angle towards the sunlight and from multiple perspectives. A qualified paint surface should be smooth, free of orange peel or water ripple defects, and there should be no color difference in vulnerable areas such as the bumper and car body, door edges, and left and right exterior rearview mirrors. 3. For metallic and pearlescent paints, you can also judge by observing the uniformity of the aluminum powder or mica particles in the paint. It is important to note that if you are unsure whether some stains on the car are scratches, it is best to use a damp cloth to wipe them off, and avoid scratching with your fingers. 4. Check the lower right corner of the car windows for relevant markings. Only original factory glass will have these marks, preventing the glass from being replaced after leaving the factory.

How to Eliminate Odors in the Car?

Methods to eliminate odors are as follows: 1. Fruit Peel Deodorization: Many people use fruit peels to remove odors in the car, which is effective and simple. It is recommended to use pomelo or orange peels as they not only have strong absorption capabilities but also emit a fruity fragrance, acting like air fresheners while improving air quality. 2. Vegetable Deodorization: Onions, known for making people tear up, are also effective against car odors. Slice a few onions, place them in a water basin, stir, and then put them in the car to remove odors. 3. Vinegar Odor Removal: Vinegar can kill airborne bacteria and viruses, stabilize formaldehyde levels, and neutralize alkaline components from cigarette smoke, making it suitable for new cars or those with heavy smoke and alcohol odors. Prepare a towel, a basin of water, and a bottle of vinegar. Dip the towel in the vinegar-water mixture and wipe seats, panels, glass, etc. Then, close the doors and windows to seal the car for a while. However, mix the water and vinegar right before use. 4. Charcoal Bags: Many car owners place activated charcoal or bamboo charcoal bags in their cars. Bamboo charcoal absorbs formaldehyde and is compact and easy to position. Owners can place the bags anywhere in the car as needed, but remember to remove the plastic packaging from new charcoal bags promptly to ensure effectiveness.

What to Do If Your Car Key Falls into Water?

Our current car keys generally come in two types: one is a purely mechanical key, usually a spare key, which contains an anti-theft chip and is waterproof. Therefore, this type of key is not afraid of falling into water. The other is a remote control key, which can remotely control the opening and closing of car doors based on different vehicle configurations, featuring keyless entry and one-button engine start functions. If the key gets damaged by water, we can only use its mechanical key to enter the car, but the anti-theft chip inside the remote key is also waterproof, so we can still start the engine in emergencies. If we need to replace it with a new key, we must order it from the manufacturer using the vehicle's chassis number and then match it online. This process usually takes about a month. Some people in urgent need might go to specialized key-matching repair shops, but this poses risks for Volkswagen's anti-theft system, as many of these shops use methods similar to hackers to crack and match keys. There's a possibility that when matching the vehicle's anti-theft components through official channels later, the entire vehicle's anti-theft system might be locked because Volkswagen's anti-theft server could detect unauthorized intrusion into the vehicle's anti-theft system. In such cases, replacing the entire vehicle's anti-theft components would be necessary, resulting in significant losses. If a remote key falls into water, the first step is to remove the key battery and shake out the water inside. Then, we need to use compressed air to dry the interior. Of course, most of us don't have compressed air handy. In such cases, we can use a hairdryer with cold air to blow out the water for about 1 minute, followed by warm air. The hairdryer should not be too close to the key, mainly to use the warm air to evaporate the moisture inside. After that, we should wrap the key in a pile of desiccants from similar food items to absorb the remaining moisture, if desiccants are not available. Then, place the key in a bowl of rice, although many say rice has poor moisture absorption. But this is one of the better emergency methods we can think of. Wait until the next day to reinstall the battery and test it. Although this method is not 100% effective, it has saved many people's keys. So after reading this method, it's worth remembering—you might need it someday.

What is the normal tire pressure for Chery Arrizo 5?

Chery Arrizo 5's normal tire pressure range is 2.4-2.5bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2bar in winter and reduced by 0.1bar in summer. If you want to check the current tire pressure of Arrizo 5 during daily driving, you can activate the tire pressure monitoring system, and the tire pressure value will be displayed on the central LCD screen of the instrument panel. The specific method is to press the LCD adjustment button on the combination instrument on the left side of the steering wheel and switch to the tire pressure monitoring system interface. If the tire pressure monitoring indicator light comes on (a yellow symbol, an irregular circle without a seal on top, four small spikes at the bottom, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure. The system usually alerts when the pressure is below 1.8bar or above 3.0bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset. After inflating the tires, if the tire pressure is not reset in time, the system will still record the previous data, causing the tire pressure monitoring indicator to light up. Simply reset the tire pressure to resolve this issue. Damaged tire pressure sensor. The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the tire inflation valve. If the sensor is damaged due to impact while driving, the tire pressure warning light will also come on. For sensor damage issues, only replacement with a new part is possible.
