What does DEF mean for diesel vehicles?

DEF in diesel vehicles indicates that the vehicle's urea is nearly depleted, reminding the owner to replenish the diesel exhaust fluid as soon as possible. DEF, known as Diesel Exhaust Fluid, is a consumable required in SCR (Selective Catalytic Reduction) technology. It is a liquid used in SCR systems to reduce nitrogen oxide emissions from diesel vehicle exhaust. Failure to use DEF, or using DEF of insufficient purity or inferior quality, will result in the vehicle's engine automatically reducing speed. Additionally, inferior quality DEF can contaminate the catalyst in the SCR catalytic reaction tank, leading to severe consequences.

Can 4S Shop Paint Last for 10 Years?

4S shop paint can last for 10 years, but noticeable aging phenomena will inevitably appear after 10 years of use. Here are the relevant details: Electrocoat layer: Most standard repair shops apply three layers of paint, namely the primer coat, color coat, and clear coat. The main difference from factory paint is the absence of an electrocoat layer. The electrocoat layer requires immersing the vehicle in a paint tank and applying electricity to adhere the paint to the frame, a process generally unavailable at 4S shops and repair centers. Painting process: The painting process at 4S shops and repair centers can roughly be divided into cleaning and sanding, priming (mid-coat), painting, baking, and polishing.

Is it serious if the side of the tire is peeling?

If only a small part of the tire sidewall is peeling, it generally does not have a significant impact on the vehicle. However, if there is a cut or gash on the tire sidewall, it is advisable to avoid continued use, as the tire may be prone to blowouts during high-speed operation. Below is some relevant information: Most car tires have tread wear indicators. These indicators are located at the bottom of the tread grooves and are approximately 1.6 mm in height, which represents the groove depth. If the tire wear reaches the level of these indicators, the tire should be replaced immediately, as severe wear can compromise driving safety.
