Detailed Description

Wix designs the 51258 oil filter for OEM-recommended oil change intervals, typically 3,750 to 10,000 miles and not more than 12 months, depending on vehicle service requirements. The filter is intended for normal driving as well as severe conditions such as stop-and-go traffic, dirt roads, construction sites, short trips, and interstate travel. Its media and capacity are selected to balance filtration efficiency with contaminant-holding ability, helping maintain oil cleanliness over the service interval.

For fitment-based searches, this part is commonly selected for 1974-1983 Jeep J10, 1974-1983 Jeep J20, 1974-1983 Jeep Cherokee, 1972-1983 Jeep Wagoneer, 1971-1981 Jeep CJ5, and 1976-1981 Jeep CJ7. It also appears in classic Buick, Pontiac, Cadillac, Oldsmobile, and Land Rover applications, including 1967-1980 Pontiac LeMans and 1970-1974 Land Rover Range Rover.

What It Helps Address

• Oil contamination from normal engine wear
• Dry starts after shutdown when the filter drains back
• Reduced filtration performance during extended service intervals
• Maintenance needs for older Jeep, Pontiac, Buick, Cadillac, and Oldsmobile engines
• Routine oil service in stop-and-go or severe-duty driving

Installation Notes and Tips

Verify thread size, filter height, and gasket sealing surface before installation. Pre-fill only if the vehicle service procedure allows it, and always lubricate the gasket before tightening to the manufacturer’s specification. Replace the filter at the same interval as the oil change, especially on vehicles used for short trips or severe-duty driving.
