Detailed Description

Protec 174 is an engine oil filter designed for normal city and highway use where conventional motor oil and regular service intervals are followed. The filter uses enhanced cellulose media to capture contaminants while maintaining oil flow, and its anti-drain back valve helps reduce dry starts after the engine sits. With a 3/4-16 thread, closed top inner diameter, and spin-on construction, this filter matches the needs of many older Volvo engines. This part cross-references Wix 51311 and FRAM PH2800 for the same application. For shoppers searching for a Volvo 850 oil filter, Volvo S70 oil filter, or Volvo V70 spin-on oil filter, Protec 174 provides a straightforward replacement option.

What It Helps Address

• Engine wear caused by dirty oil circulation
• Oil drain-back after shutdown
• Reduced filtration performance during routine service intervals
• Inconsistent oil flow in everyday driving conditions
• Maintenance needs for older Volvo engines using conventional oil

Installation Notes and Tips

Install Protec 174 as a spin-on oil filter using the correct torque procedure for the vehicle. Verify thread size, gasket sealing surface, and filter clearance before installation. Replace the filter during each oil service and follow the vehicle manufacturer’s recommended oil change interval. Confirm application by year, make, and model before ordering, especially on Volvo 740, 850, 940, 960, S70, S80, S90, V70, V90, and C70 vehicles.

Quality Assurance

Protec lists laboratory test performance data referenced to ISO 454812, including dirt-holding and efficiency measurements. The filter is built with a burst pressure rating of 331 and a bypass relief setting of 16, supporting consistent operation in normal service conditions.
