Original MANN-FILTER Oil filter W 815/5 – For Passenger Cars

Overview of the MANN‑FILTER Oil Filter W 815/5

The MANN‑FILTER Oil Filter W 815/5 is a high‑performance filtration solution engineered specifically for passenger cars. Designed with precision and durability in mind, this filter delivers superior protection for the engine’s lubrication system by removing contaminants that can cause wear or failure.

Key Design Features

• Advanced Filter Media: Utilizes a multi‑layered filtration matrix that captures particles as small as 0.5 µm, ensuring clean oil flow and extended engine life.
• Robust Housing: Constructed from high‑strength polypropylene with reinforced seams to withstand pressure fluctuations and temperature variations typical in automotive engines.
• Sealed Seal Technology: Equipped with a double O‑ring seal system that prevents oil leakage during installation, maintaining optimal oil pressure.
• Non‑Return Valve: Integrated check valve guarantees unidirectional flow, preventing backflow and preserving filter integrity.

Compatibility and Application

The W 815/5 is engineered to fit a wide range of passenger car models. Its standardized dimensions (M20 × 1.5 thread) make it suitable for many European and Asian vehicles, including popular makes such as Renault, Isuzu, GM, BYD, and others. The filter’s design aligns with OEM specifications, ensuring seamless integration into the engine’s oil circuit.

Performance Benefits

• Enhanced Engine Protection: By trapping dirt, metal shavings, and other contaminants, it reduces wear on bearings, pistons, and camshafts.
• Improved Fuel Efficiency: Clean oil maintains optimal viscosity, reducing friction losses and contributing to better fuel economy.
• Extended Oil Life: Keeps the oil free from impurities that can accelerate oxidation, allowing longer intervals between oil changes.

Installation Guidelines

1. Warm up the engine to operating temperature to ensure oil flow.
2. Drain the existing oil and remove the old filter carefully.
3. Clean the mounting surface with a lint‑free cloth to eliminate debris.
4. Apply a thin layer of fresh oil on the filter’s rubber seal before screwing it in.
5. Tighten the filter by hand until snug, then give an additional 1/4 turn with a wrench—avoid overtightening.
6. Reinstall the drain plug and refill the engine with the recommended oil type.

Maintenance Tips

• Inspect the filter housing for cracks or damage before each installation.
• Check the O‑ring seal for wear; replace if it shows signs of deformation.
• Follow the vehicle manufacturer’s service schedule to determine optimal oil change intervals.
