Why does engine oil turn yellow?

What is the fuel consumption of the Qashqai?

The fuel consumption of the Qashqai is 6.8-7.3L/100km. Additional Information: Methods to reduce fuel consumption are as follows: 1. Regular maintenance: Regular maintenance can reduce the failure rate of the car and also lower fuel consumption. Maintenance includes replacing parts such as spark plugs, oil filters, brake fluid, radiator coolant, air filters, power steering fluid, transmission fluid, etc. Keeping the vehicle in optimal condition helps reduce fuel consumption. 2. Avoid hard acceleration: Hard acceleration only shortens driving time by 4%, but increases fuel consumption by 37%-40%. On typical urban roads, the speed is usually maintained at 50 km/h, with engine RPM around 2000-2500. On highways, the speed is generally 90-110 km/h. For every 10 km/h increase in speed, fuel consumption increases by 10%. Avoid hard acceleration as RPM is the biggest factor affecting fuel consumption. 3. Reduce weight: For every 100KG increase in vehicle weight, fuel consumption increases by 4%-5%. 4. Maintain tire pressure within the normal range: Checking tire pressure not only benefits fuel consumption but also ensures driving safety. Develop a habit of checking tire pressure daily. Generally, the front tire pressure should be 2.2-2.3, and the rear tire pressure should be 2.4-2.5.

What kind of engine oil can be used for the Mazda 3 Axela?

The manufacturer recommends 0W-20 full synthetic or 5W-30 semi-synthetic engine oil for the Mazda 3 Axela. The oil filter models for the Mazda 3 Axela are: Mann: W67/1, Bosch: 0986AF0063, Mahle: OC980. Below are the precautions for using engine oil in the Mazda 3 Axela: 1. For new cars under normal driving conditions, if synthetic oil is used, the oil can generally be changed every 10,000 kilometers, and in some cases, it can even be extended to 20,000 kilometers. 2. "Normal driving" refers to frequent highway driving with minimal stop-and-go traffic. However, if you often drive in the city, encountering traffic lights everywhere and frequent traffic jams, with most trips not exceeding more than a dozen kilometers, this type of driving is considered "severe driving." Under "severe driving" conditions, engine wear is greater, and the requirements for engine oil are higher. Therefore, it is recommended to shorten the oil change interval to effectively protect the engine. 3. After prolonged use, engine oil accumulates a large amount of impurities. If the oil is not replaced in time, these impurities can wear down the engine and shorten the vehicle's lifespan.

What is the service life of a Passat battery?

Whether it's a maintenance-free battery or a conventional battery, the normal service life is around 2-3 years. With careful maintenance, it can last 3 to 4 years, equivalent to a driving mileage of 60,000 to 90,000 kilometers. If the battery cannot be charged or the starter is weak, and the headlights are noticeably dimmer, the battery should be removed and charged for 12-24 hours with a charger. Below are precautions for using the battery: 1. When the car lights are dim and red, the horn sounds weak, and the starter operates sluggishly: Stop using the battery immediately and charge it right away. Try to increase charging opportunities during use and keep the battery fully charged. In winter, ensure the battery remains fully charged to prevent the electrolyte from freezing due to low density, which could damage the battery. 2. If the first start attempt fails, avoid repeatedly trying to start the engine: From the perspective of automotive working principles, continuous starting of the motor will definitely cause excessive battery discharge and damage. The interval between subsequent start attempts should be more than 5 seconds.

What are the reasons for Audi's oil burning?

Here are the reasons for Audi's oil burning: 1. Differences between domestic and international standards: When vehicles are produced domestically, modifications are made to suit the driving habits of Chinese consumers. During this process, oil burning issues may arise due to differences between domestic and international standards. 2. Carbon deposits: Carbon deposits easily form in the combustion chamber, and a large amount of carbon accumulates in the piston grooves. When the piston rings stick together, a sealing lock occurs, significantly reducing the oil seal's ability and blocking the oil holes, preventing normal oil circulation and increasing oil consumption. 3. Excessive clearance: This is also a condition that occurs during the production and design process. Audi's piston walls are very thin, making it easy for oil to enter the combustion chamber during operation. This leads to the main cause of oil burning. With oil present and a combustion method, oil reduction is inevitable. 4. Aging reasons: Corrosion and aging of the valve oil seals and aging of the front and rear crankshaft oil seals are also major causes of oil burning. Prolonged operation allows oil to enter the combustion chamber. Oil leaks further increase oil burning, and only regular inspection and replacement can solve this issue. 5. Other reasons: Damage to the oil seal between the turbocharger and intake pipe, high fuel content in the oil, clogged oil filter, clogged air filter, damaged or clogged exhaust valve, incorrectly installed piston rings, overfilled oil, and dirty throttle valves can all cause oil burning. Here are the solutions for oil burning: 1. Use high-quality oil: Oil is highly susceptible to corrosion and aging under prolonged high temperatures, causing the oil film to thin and more easily enter the combustion chamber to participate in combustion. Therefore, using high-quality oil can significantly delay this phenomenon. 2. Pay attention to the cleanliness of the fuel system: Carbon deposits are inevitably produced during fuel combustion, and carbon deposits are the root cause of some car failures, such as aging valve oil seals and increased piston-cylinder wall clearance, which are directly or indirectly related to carbon deposits. Therefore, keeping the fuel system clean is very helpful in preventing oil burning, although this requires the use of high-quality fuel additives. 3. Use external aids: As mentioned above, the cleanliness of the fuel system and the oil's anti-aging properties are key factors in preventing oil burning. Considering the current domestic fuel quality, it is necessary to use high-quality oil and fuel additives to achieve this, which is also the key to solving oil burning without disassembly and repair.

Which types of car insurance are better to buy?

Here are some must-have insurances for cars: 1. Compulsory Traffic Accident Liability Insurance: First is the compulsory traffic accident liability insurance. This is a mandatory insurance that every motor vehicle must purchase. It provides compensation by the insurance company for losses and casualties caused by traffic accidents involving the insured vehicle. This must be purchased and cannot be arbitrarily canceled. Once canceled, it is illegal. 2. Vehicle Damage Insurance: Vehicle damage insurance refers to compensation provided by the insurer according to the contract when the insured vehicle suffers damage due to natural disasters or accidents within the scope of insurance liability. However, natural disasters here include earthquakes. 3. Third-Party Liability Insurance: This insurance is referred to as 'third-party insurance' for short. It means that if the car owner or an authorized qualified driver causes a traffic accident during the use of the vehicle, resulting in injury to a third party or damage to property, the insurance company will provide compensation. The limit of this insurance is chosen by the car owner, i.e., the insured. 4. Passenger Liability Insurance: This insurance is also known as 'seat insurance' or 'passenger insurance', responsible for compensating injuries to specified seat occupants caused by the vehicle. The car owner can set compensation limits for each seat as needed. This insurance is equivalent to accidental injury insurance.
