MANN‑FILTER Oil Filter W 933/1 – For Passenger Cars

The Original MANN‑FILTER Oil Filter W 933/1 is a high‑performance filtration solution designed specifically for passenger cars. It delivers superior protection for the engine by trapping contaminants, maintaining oil cleanliness, and extending engine life.

Key Features

• Advanced Filtration Technology: Utilises a multi‑layer filter media that captures particles as small as 0.5 µm, ensuring the oil remains free from dirt, metal shavings and other impurities.
• Anti‑Return Valve: Equipped with a reliable one‑way valve that prevents backflow of contaminated oil into the engine, preserving filtration integrity throughout operation.
• Robust Construction: Made from high‑grade polypropylene housing that resists cracking and deformation under high pressure and temperature conditions.
• Easy Installation: Threaded 3/4‑16 UNF design allows for quick screw‑on installation without the need for special tools.
• Wide Compatibility: Approved for use in a broad range of passenger vehicles, including models from Ford, Nissan, LTI, and many others. It is a direct replacement for the older W 932/81 filter.
• Long‑Lasting Performance: Maintains optimal oil flow and pressure, reducing wear on engine components and improving fuel efficiency.

Technical Specifications

Installation Guide

1. Prepare the Vehicle: Warm up the engine to operating temperature, then shut off and let it cool slightly. Locate the oil filter housing.
2. Remove Old Filter: Use an oil filter wrench or hand‑tighten if necessary. Allow any residual oil to drain into a container.
3. Clean Housing: Wipe the threads of the housing with a clean rag to remove old gasket material and debris.
4. Apply Gasket (if required): Some models may need an additional rubber gasket; apply it according to manufacturer instructions.
5. Screw in New Filter: Hand‑tighten the MANN‑FILTER W 933/1 until snug, then give a final quarter turn. Do not overtighten to avoid damaging the housing.
6. Check for Leaks: Start the engine and observe the filter area for any oil leakage. Tighten slightly if necessary.
7. Dispose of Old Filter Properly: Place the used filter in a sealed container for recycling or disposal according to local regulations.

Performance Benefits

• Engine Protection: By filtering out fine particles, the filter reduces wear on bearings, pistons, and camshafts, thereby extending engine longevity.
• Fuel Efficiency: Clean oil flows more smoothly through the engine, reducing friction losses and improving mileage.
• Reduced Maintenance Costs: Fewer contaminants mean less frequent oil changes are required, saving time and money over the vehicle’s life.
• Environmental Impact: Efficient filtration reduces oil consumption and emissions associated with engine wear.

Compatibility Overview

The MANN‑FILTER W 933/1 is engineered to fit a wide array of passenger car models. Below are some representative vehicle families that have been verified for compatibility:

• Ford: Focus, Fiesta, Mondeo, and many other compact and mid‑size cars.
• Nissan: Micra, Qashqai, Juke, and various SUV variants.
• LTI (Lancia): Delta, Kappa, and related models.
• Other brands such as Maverick, Terrano II, and certain Pickup configurations also support this filter.

Quality Assurance

The filter undergoes rigorous testing in accordance with European automotive standards. Each unit is inspected for:

• Thread integrity and proper sealing.
• Filter media density and uniformity.
• Pressure drop performance under simulated engine conditions.
• Durability against temperature cycling and vibration.

Maintenance Recommendations

While the MANN‑FILTER W 933/1 is designed for long service intervals, it is advisable to:

• Replace the filter at every oil change or as recommended by the vehicle manufacturer.
• Avoid using low‑quality oils that may introduce excessive contaminants.
• Inspect the filter housing and gasket for wear during routine maintenance checks.
