Original MANN-FILTER Oil Filter W 950/39 – For Trucks, Buses and Utility Vehicles

Product Overview

The MANN‑FILTER Oil Filter W 950/39 is a high‑performance filtration solution engineered specifically for heavy‑duty commercial vehicles such as trucks, buses, and utility fleets. Designed to meet the rigorous demands of large diesel engines, this filter delivers superior protection against contaminants while maintaining optimal oil flow.

Key Design Features

• Robust Construction: The filter housing is fabricated from durable steel with a reinforced gasket system that resists cracking and ensures a secure seal under extreme pressure conditions.
• Advanced Filter Media: A multi‑layer media architecture captures particles as small as 5 µm, providing exceptional filtration efficiency for both fine dust and larger debris.
• Optimized Flow Path: The internal geometry is engineered to minimize pressure drop, preserving engine performance while delivering clean oil to critical components.
• Long‑Lasting Seal: The filter’s rubber seal is formulated for high temperature stability and chemical resistance, extending service life even in harsh operating environments.

Engine Compatibility

The W 950/39 filter is specifically calibrated for a range of heavy‑duty diesel engines. It is compatible with:

• Nissan heavy‑truck series (e.g., NV350, NV370)
• TEMSA and SOLARIS commercial vehicle platforms
• DAF, Iveco, and AVIA powertrains commonly used in long‑haul trucking
• Other OEM engines that specify a 27 mm threaded inlet and require a filter size of 39 mm.

Performance Benefits

Installing the MANN‑FILTER W 950/39 offers several tangible advantages for fleet operators:

• Extended Engine Life: By trapping contaminants before they reach bearings, pistons, and turbochargers, the filter reduces wear and tear.
• Improved Fuel Efficiency: A clean oil system maintains optimal lubrication, which can translate into measurable fuel savings over time.
• Reduced Maintenance Intervals: The high‑capacity media allows for longer service intervals without compromising protection.
• Consistent Performance in Harsh Conditions: Whether operating in dusty construction sites or humid coastal routes, the filter maintains its integrity and filtration capability.

Installation Guide

1. Preparation: Ensure the engine is cool and disconnect the battery to prevent accidental start‑up.
2. Drain Old Oil: Position a drain pan beneath the oil filter housing, remove the old filter, and allow residual oil to drain completely.
3. Clean Housing: Wipe the filter mounting surface with a lint‑free cloth to remove any debris or old gasket material.
4. Apply New Gasket: Place the new rubber seal onto the housing, ensuring it sits flush and evenly.
5. Install Filter: Thread the W 950/39 filter onto the housing clockwise until snug. Tighten to the manufacturer’s specified torque (typically 12–15 Nm).
6. Refill Oil: Add fresh engine oil to the recommended level, then reconnect the battery.
7. Check for Leaks: Start the engine and inspect the filter area for any signs of leakage. Tighten further if necessary.

Maintenance Tips

• Inspect the filter housing gasket during each oil change; replace if cracked or deformed.
• Use only high‑quality engine oil that meets OEM specifications to complement the filter’s performance.
• Avoid overfilling, as excess oil can cause foaming and reduce filtration efficiency.
• Keep the vehicle’s operating environment clean; regular cleaning of air intake systems reduces particulate load on the filter.
