Oil Filter Guide: Spin-On vs Cartridge, Specs & Wholesale Pricing
Oil filter selection guide — spin-on vs cartridge types, filtration ratings, bypass valve specs, and OE cross-reference for wholesale buyers.
Oil filters are the highest-frequency replacement part — changed every 5,000-15,000 km. For distributors, they offer consistent recurring revenue.
Spin-On vs Cartridge
Spin-on filters are self-contained metal canisters with integrated bypass and anti-drain valves. Popular in North American and older Asian vehicles. Easy 15-second install. Cartridge filters are just the element that installs into a permanent housing — increasingly common in European and modern vehicles. Less waste, lower cost, more environmentally friendly.
Key Specifications
Filtration efficiency: 95% at 20 microns is standard, premium achieves 98%. Burst pressure: quality filters handle 200+ PSI. Bypass valve: typically 8-12 PSI differential — opens when clogged to maintain oil flow. If set too low, dirty oil passes through prematurely.
