Detailed Description

WIX part number 51085 is an engine oil filter engineered for conventional, synthetic, and synthetic-blended motor oils. It is built to handle normal driving and severe-duty use such as stop-and-go traffic, short trips, dirt roads, construction sites, and interstate travel. The filter media is designed to trap more dirt and contaminants than Protec in severe conditions, while maintaining a practical balance of capacity and efficiency. Laboratory testing cited by WIX shows high filtration performance at fine particle sizes, supporting clean oil circulation over the service interval.

This part cross-references ACDelco PF13 and FRAM PH16 for the same application.

What It Helps Address

• Oil contamination from dust, soot, and wear particles
• Reduced filtration performance during extended service intervals
• Dry engine starts after the vehicle sits for a period of time
• Oil flow concerns in stop-and-go or severe driving conditions
• Routine maintenance on vehicles that use the 3/4-16 thread filter format

Installation Notes and Tips

Verify the filter thread size, gasket sealing surface, and overall height before installation. Replace the filter at the manufacturer-recommended oil change interval and pre-fill only if the vehicle service procedure allows it. Confirm the correct application for your Ram 2500, Jeep Wrangler, or Chrysler Pacifica by matching the OE part number and service specifications.
