About the Bosch Workshop Oil Filter Line

The Bosch Workshop Oil Filter line focuses on delivering dependable filtration solutions tailored for professional automotive service environments. The 72198WS model is part of this line, offering features such as a cellulose paper filter media and integrated valves that meet the demands of Audi and Volkswagen engines requiring precise oil filtration and pressure control.

Technical Details and Performance

This Bosch oil filter uses cellulose paper as its filtering material, providing a micron rating of 30 to effectively trap contaminants while maintaining optimal oil flow. The spin-on design simplifies replacement, and the anti-drain back valve prevents oil from draining out of the filter when the engine is off, reducing wear during start-up. The bypass relief valve activates between 30 and 40 PSI to ensure oil continues circulating even if the filter becomes clogged. With a burst pressure rating of 200 PSI, this filter maintains structural integrity under demanding conditions.

This filter is designed to meet the specific oil filtration requirements of these vehicles, ensuring proper engine protection and performance.

Common Issues Addressed by This Oil Filter

• Prevents engine wear caused by contaminants in the oil
• Reduces risk of oil starvation during cold starts with anti-drain back valve
• Maintains oil pressure with bypass relief valve during filter clogging

• Ensures reliable sealing with nitrile gasket to prevent leaks

Installation Notes and Tips

When installing the Bosch 72198WS oil filter, ensure the engine is cool and the old filter is fully drained before removal. Apply a thin layer of clean engine oil to the nitrile gasket to improve sealing and ease installation. Tighten the filter by hand until the gasket contacts the mounting surface, then follow vehicle-specific torque specifications if available. The 3/4-16 thread size ensures compatibility with the designated Audi and Volkswagen models.
