Why Should You Fill Up the Tank When a Car Is Parked for a Long Time?

When a car is parked for a long time, it is not advisable to fill up the tank completely, as gasoline can oxidize severely over time and form gum deposits. Below is an introduction to gasoline: 1. Definition of gasoline: Gasoline is a volatile, flammable liquid hydrocarbon mixture distilled and cracked from petroleum, used as fuel. 2. Key characteristics of gasoline: The important properties of gasoline include volatility, stability, anti-knock quality, corrosiveness, and cleanliness. 3. The difference between 95-octane and 92-octane gasoline: 95-octane gasoline has better anti-knock properties than 92-octane. The better the anti-knock quality, the less likely the engine is to experience knocking.

Does a Front Crankshaft Oil Seal Leak Need Repair?

The front crankshaft oil seal leak needs repair. Over 90% of oil leaks occur because the rubber sealing ring loses a significant amount of plasticizers and softeners due to prolonged exposure to alternating hot and cold temperatures, resulting in oil dripping. The solution to the oil leak is to disassemble the engine and replace the oil seal. Below is some relevant information about oil seals: 1. Introduction: Oil seals are commonly referred to as general sealing components, simply put, they are seals for lubricating oil. They are mechanical components used to seal grease (oil is the most common liquid substance in transmission systems and also generally refers to liquid substances). They isolate the components in the transmission system that require lubrication from the output components, preventing lubricant leakage. Seals used for static sealing and dynamic sealing (generally reciprocating motion) are called oil seals. 2. Representative Form: The representative form of an oil seal is the TC oil seal, which is a double-lip oil seal with a self-tightening spring completely encased in rubber. The commonly referred to oil seal often means this type of TC skeleton oil seal.

What grade of gasoline should a BMW X7 use?

BMW X7 recommends using 98-octane gasoline. 98-octane gasoline has higher purity and better anti-knock performance, which can better promote the engine's internal work. Here is some additional information: 1. Differences in gasoline: The main difference lies in the content of n-heptane and isooctane. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. 98-octane gasoline is a mixture of 98% isooctane and 2% n-heptane. Additionally, the gasoline octane rating represents the fuel's anti-knock performance—the higher the rating, the better the anti-knock performance. 2. Precautions: Try not to wait until the fuel light comes on before refueling. Because the fuel pump is located inside the fuel tank and operates at a high temperature continuously, being immersed in fuel helps to cool it effectively. When the fuel light comes on, it indicates that the fuel level is below the fuel pump. If you always wait until the light comes on to refuel, it will shorten the fuel pump's lifespan. Having too little fuel or running out of fuel could even burn out the fuel pump.

What is the reason for the yellow exclamation mark on the Baojun 510 dashboard?

The appearance of an exclamation mark on the car dashboard indicates an abnormality or malfunction in the corresponding system. Below is a detailed introduction to the exclamation mark warning light: General faults: A triangle with an exclamation mark inside indicates a fault in the vehicle's general performance, components, or functions. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, engine oil pressure sensor failure, etc. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic transmission fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a fault in the transmission or that the transmission lubricant is below the normal range. The transmission oil should be replaced promptly. Brake system fault: A circle with an exclamation mark inside parentheses represents a brake system warning, mainly indicating a brake system malfunction or low brake fluid level. The brake system should be inspected immediately to avoid accidents. Tire pressure abnormality: An exclamation mark with a horizontal line below parentheses represents the tire pressure monitoring warning light. This light will illuminate when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a fault in one of the vehicle's lights. Solution: Visit a 4S shop for inspection as soon as possible, or check yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue. In addition, during daily vehicle use, the warning lights displayed on the dashboard are divided into two colors: yellow and red: Yellow indicates a fault in the corresponding system that is not very serious. Reduce speed and proceed to a repair shop to eliminate potential safety hazards. Red indicates a very serious problem in the corresponding system. In such cases, do not continue driving. Pull over immediately and seek professional assistance to prevent unpredictable risks to the vehicle and personal safety. Note: When the car is started, all lights will illuminate for an automatic system check and will turn off after the check is completed. If a light does not turn on when the ignition is switched on, remains lit, or lights up while driving, it indicates a fault in the related system. In such cases, seek professional help promptly to inspect and eliminate potential safety hazards.

What is the reason why the BMW 5 Series coolant level is too low and it restarts fine?

The reason why the BMW 5 Series coolant level is too low and it restarts fine is due to insufficient coolant in the radiator. Here are the details: 1. Introduction: Coolant is an essential part of a car engine, composed of water, antifreeze, and additives. It circulates in the engine cooling system, carrying away excess heat generated during engine operation to ensure the engine runs at the proper working temperature. In high-temperature conditions, if the concentration and level of the coolant are not within the normal range, it can easily cause engine failure or even overheating. 2. Precautions for using antifreeze: Try to use the same brand of antifreeze. Different brands of antifreeze may have varying production formulas, and mixing them could lead to chemical reactions between multiple additives, rendering them ineffective. Most antifreeze products have a validity period of two years (some products may last longer), so ensure the product is within its validity period when adding it.
