Car window film should be applied on the inside of the car glass because installing it on the interior side protects it from wind and rain, slowing down aging and thus extending its service life. Below is relevant information: Heat and Sun Protection: The film can effectively block a significant amount of heat generated by infrared rays. UV Protection: Medium and long waves of ultraviolet rays can penetrate thick glass, but applying heat insulation film can block most UV rays, preventing skin damage and reducing the aging of car interiors. Safety and Explosion Protection: The base layer of the film is made of polyester, which provides excellent tear resistance and puncture prevention. Combined with the adhesive layer of the film, the strengthened glass can prevent injuries to drivers and passengers caused by accidental glass breakage.

Does the Passat dry clutch transmission require oil change?

Passat dry clutch transmission does not require oil change. Volkswagen dry clutch transmission maintenance cycle: The manufacturer specifies it as maintenance-free, basically requiring no replacement. This is because the original factory-installed oil in this transmission is a low-viscosity fully synthetic gear oil with an exceptionally long service life, typically not needing replacement within 200,000 kilometers unless special circumstances arise. Replacement is only necessary if issues like water contamination or oil degradation occur. If replacement were required, the manufacturer would clearly specify the service interval. Function of transmission fluid: Transmission fluid primarily refers to the lubricating oil for gearboxes and rear axles. It differs from engine oil in terms of operating conditions, composition, and performance characteristics. Gear oil mainly serves to lubricate gears and bearings, prevent wear and corrosion, and assist in heat dissipation for the gears.
