Long-term use can cause irreversible damage to the vehicle's fuel system. Related information is as follows: 1. Fuel classification: Based on the scale of petroleum refining enterprises, they can be divided into "central refineries" and "local refineries." "Local refineries" refer to small-scale regional oil refineries, which mainly produce low-end industrial oils. However, they may also provide fuel products in their respective regions, though the quality of these fuels may not meet standards. In some areas, there are even specialized training courses for "naphtha blending into gasoline," and some "local refineries" use naphtha to blend gasoline, which is then sold to private gas stations for huge profits. 2. The 'Big Three' oil companies: Using such blended fuels can corrode the fuel system, and long-term use may lead to irreversible damage to the vehicle's fuel system. In contrast, the 'Big Three' oil companies, which are part of "central refineries," have mature refining processes and comprehensive testing standards. The best fuel quality in China is generally found at the direct-operated gas stations of the 'Big Three' oil companies.

What are the criteria for identifying yellow-label vehicles?

Yellow-label vehicles are identified based on their exhaust emission standards. The term 'yellow-label vehicle' collectively refers to gasoline vehicles with emission levels below China's National I standard and diesel vehicles below the National III standard when they were first manufactured. These are typically vehicles with high pollution output, concentrated emissions, and poor emission stability. Additional information: Environmental protection labels are divided into green and yellow categories. Gasoline vehicles that meet the National I or higher emission control requirements and standard limits upon initial registration, as well as diesel vehicles compliant with National III standards or above, are issued green environmental labels. All other vehicles receive yellow environmental labels (i.e., yellow-label vehicles).

Do tires need to be replaced after 5 years of use?

Tires that have been used for 5 years do not necessarily need to be replaced. Car tires typically last 6-8 years before needing replacement. Tire manufacturers do not provide a definitive lifespan for tires, but generally recommend replacement after 3 to 5 years or after traveling 60,000 to 80,000 kilometers. The actual replacement should be based on the tire's mileage or wear condition after inspection. The service life of car tires is closely related to the driving environment and driving habits. Car owners should pay attention to the tire wear indicators. When the tread wear reaches 1.6 millimeters, the tires should be replaced promptly to avoid abnormalities during use that could affect driving safety. When determining whether tires need replacement, consider the following conditions: Tire sidewalls have wear limit indicators. When the tread reaches this indicator, immediate replacement is necessary. Damaged tires, such as those with cracks, bulges on the tread, or uneven wear, should also be replaced promptly. Additionally, tires that have been patched multiple times during use should be replaced. Since tires are made of rubber, they undergo varying degrees of aging over time. If tires have been in use for an extended period, regular inspections by professionals are recommended. Car tire maintenance methods: Regularly check tire pressure; remove debris from tread grooves; inspect tire wear and replace as needed based on wear condition; perform tire rotation—rotating tires ensures even wear across all four tires, preventing excessive wear.

What are the effects of a slight exhaust pipe leak?

The main effects of a slight exhaust pipe leak are as follows: 1. It can affect the car's power and increase fuel consumption. The impact is more significant on turbocharged cars and relatively minor on naturally aspirated cars. 2. It can amplify the car's noise. Additional details: The impact of an exhaust pipe leak also depends on the location of the leak: 1. If the leak is in the front section, it can reduce exhaust backpressure, leading to weaker engine performance, difficulty in starting, and increased fuel consumption. 2. If the leak is in the middle section, the water produced by the exhaust pipe can corrode it over time, eventually causing rust. 3. If the leak is in the tail section, it has no effect on the car.

Is It Necessary to Install Mudguards on a Car?

It is necessary to install mudguards on a car. Here is some information about car mudguards: 1. Car mudguards primarily serve to block mud. 2. Generally, during rainy weather, especially on muddy roads, car tires tend to accumulate a lot of mud, which can sometimes splash onto the car body. Installing mudguards can help protect the car from mud and debris. Additional information: 1. Mudguards are plate-like structures installed behind the wheel frame, usually made of high-quality rubber or sometimes engineering plastic. 2. Mudguards are typically installed as metal, leather, plastic, or rubber panels behind the wheels of a vehicle. After installation, the mudguard protrudes about 5cm from the car body, effectively preventing flying stones and gravel from damaging the car's paint.
