Technical Details and Performance

The Wix 51799 oil filter utilizes enhanced cellulose media to trap contaminants effectively while maintaining a micron rating of 19.00, balancing filtration efficiency with oil flow. Its bypass relief valve is calibrated at 31 psi, allowing oil to bypass the filter element if it becomes clogged, preventing engine oil starvation. The filter’s burst pressure rating of 400 psi ensures it withstands high-pressure conditions common in heavy-duty engines. With a flow rate of 24-28 gallons per minute, this filter supports engines requiring substantial oil circulation. The spin-on design with a 36x1.5 mm thread size simplifies replacement and ensures a secure fit.

Compatible Vehicles and Applications

The Wix 51799 engine oil filter is compatible with a range of heavy-duty trucks and commercial vehicles that require a Class Ha, heavy-duty oil filter with these specifications. It is suitable for use in diesel and gasoline engines where a 12.184-inch height and 5.342-inch outer diameter filter is specified. This filter is often sought for maintenance on vehicles such as Freightliner, Kenworth, Peterbilt, and other similar heavy-duty truck makes and models requiring a 36x1.5 mm thread size oil filter.

Common Issues Addressed by Wix 51799 Oil Filter

• Prevents engine wear caused by contaminants in the oil
• Maintains proper oil flow under high-pressure conditions
• Protects against oil starvation with a reliable bypass valve
• Reduces risk of filter collapse due to high burst pressure rating
• Ensures consistent engine lubrication for heavy-duty applications

Installation Notes and Tips

Before installing the Wix 51799 oil filter, ensure the engine is cool and the oil system is depressurized. Apply a thin layer of clean engine oil to the filter gasket to ensure a proper seal. Screw the filter on by hand until the gasket contacts the mounting surface, then tighten according to vehicle manufacturer specifications, typically an additional 3/4 to 1 turn. Verify the thread size matches the engine’s filter mount (36x1.5 mm) to avoid cross-threading or leaks. After installation, check for leaks and monitor oil pressure during initial engine operation.
