Original MANN-FILTER Oil Filter W 930/9 – For Trucks, Buses and Utility Vehicles

MANN‑FILTER Oil Filter W 930/9 – Premium Protection for Heavy‑Duty Vehicles

The MANN‑FILTER Oil Filter W 930/9 is engineered specifically for trucks, buses, and utility vehicles. Designed to meet the rigorous demands of commercial fleets, this filter delivers exceptional filtration performance while maintaining reliable operation under harsh driving conditions.

Key Features

• High‑Capacity Filtration: The W 930/9 incorporates a multi‑stage media system that captures fine particles down to 0.5 µm, ensuring engine oil remains free from contaminants that could cause wear or failure.
• Anti‑Return Valve: A built‑in one‑way valve prevents backflow of contaminated oil, protecting the filter media and extending its service life.
• Robust Construction: The filter housing is made from high‑strength steel with a corrosion‑resistant coating, capable of withstanding vibration, impact, and temperature extremes typical in heavy‑vehicle operation.
• Standard Threading: Features a 3/4‑inch diameter, 16 UNF thread (M20x1.5) that is compatible with most commercial engine oil filter fittings.
• Easy Installation: Designed for quick replacement, the W 930/9 can be installed without special tools, reducing downtime and maintenance costs.

Compatibility

The filter is specifically tailored for a wide range of heavy‑vehicle engines. It is commonly used in:

• MERCEDES‑BENZ commercial trucks and buses (e.g., models with engine codes such as 5041315, 5057957)
• Other European manufacturers that employ the 3/4‑inch, 16 UNF oil filter standard.

Its universal thread size and robust design make it a suitable replacement for many OEM filters in heavy‑duty applications.

Performance Benefits

• Engine Longevity: By trapping microscopic contaminants, the W 930/9 reduces wear on bearings, pistons, and camshafts, thereby extending engine life.
• Fuel Efficiency: A clean oil system maintains optimal viscosity and flow characteristics, which can improve fuel economy by up to 2 % in some fleets.
• Reduced Maintenance Costs: The anti‑return valve and durable media reduce the frequency of filter changes, lowering overall maintenance expenses.

Installation Guidelines

1. Ensure the engine is cool before beginning work to avoid burns from hot oil.
2. Disconnect the battery for safety if required by your vehicle’s service manual.
3. Remove the old filter carefully, allowing any residual oil to drain into a suitable container.
4. Inspect the mounting surface for damage or corrosion; clean as necessary.
5. Apply a thin layer of fresh engine oil to the gasket area if recommended by the vehicle manufacturer.
6. Screw in the new W 930/9 filter clockwise until snug, then give an additional quarter turn to ensure a proper seal.
7. Reinstall any removed components and reconnect the battery.
8. Start the engine and check for leaks; observe oil pressure gauge for normal operation.

Maintenance Tips

• Check the filter at every scheduled oil change or after a specified mileage interval (typically 10,000–15,000 km depending on operating conditions).
• Inspect for visible signs of wear such as cracks, dents, or excessive corrosion.
• Replace the filter if it shows any damage or if oil pressure drops noticeably during operation.
