Product Details

Premium Guard Extended Life filters are built for drivers who need dependable oil filtration over longer service intervals.

With synthetic blend media and a 25 micron rating, this Premium Guard oil filter is engineered to trap fine debris while maintaining steady oil flow. The anti-drain back valve and silicone gasket help support consistent sealing and oil retention, which is important for engines that see frequent starts, towing, or extended service use. The PG4651EX is also listed across many older and newer fitments, including Ford E-Series vans, Lincoln Navigator, Mercury Grand Marquis, Mazda 6, and Honda Civic and Accord applications.

Common Problems This Filter Helps Address

• Oil contamination from normal engine wear
• Dry-start conditions after the vehicle sits
• Pressure bypass events caused by restricted filtration
• Seal leakage at the filter mounting surface
• Reduced filtration performance during extended oil service intervals

Installation Notes and Tips

Verify the engine uses an M22x1.5P threaded spin-on filter before installation. Confirm the vehicle year, make, model, and any fitment notes such as 22mm threaded engine stud or 22mm threads, since several applications require those details. Pre-lube the gasket before tightening, and follow the vehicle manufacturer’s oil change and torque procedures. For fitment examples, this part fits 2009-2014 Ford F-150, 2016-2023 Dodge Charger, and 2008-2021 Jeep Grand Cherokee, with notes varying by application.
