The routine maintenance procedure of changing oil filter is one of the most critical services for preserving engine longevity, as it removes accumulated contaminants and ensures that clean oil circulates through the engine’s lubrication system between service intervals. Sakes Auto Parts, founded in April 2016 by several powerful regional dealer representatives in Shanghai’s Anting Town, was established to address the automotive aftermarket’s demand for transformation and upgrading, and our close-interest community structure enables us to support professional technicians with changing oil filter solutions that simplify the service process while delivering uncompromising filtration quality. Through our unified management across different administrative areas and strategic capital pooling, we ensure that the oil filters used in changing oil filter procedures are manufactured with consistent thread specifications, proper gasket sealing surfaces, and precise bypass valve calibration that ensure leak-free installation and optimal filtration performance throughout the service interval. Our deep expertise in Volkswagen and Audi platforms has given us unique insights into the specific requirements for changing oil filter on these vehicles, where cartridge-style filters, canister-style filters, and integrated filter housing designs demand components that match original equipment specifications for fitment, sealing, and filtration efficiency. By integrating research, development, production, sales, and service under one unified structure, we deliver changing oil filter solutions that help professional technicians perform efficient, accurate oil service, reduce the risk of leaks or filter-related engine damage, and provide end consumers with the confidence that their vehicle’s engine is protected by high-quality filtration components that maintain oil cleanliness and engine reliability.
