Motorcraft FL-2124S Oil Filter 12-Pack — The NEWEST Genuine OEM Oil Filter for 2011-2025 Ford Super Duty 6.7L V8 Powerstroke Diesel
The Motorcraft FL-2124S is the CURRENT factory-standard oil filter for every 2011-2025 Ford Super Duty truck equipped with the 6.7L V8 Powerstroke diesel engine. This is the UPDATED replacement for the older FL-2051S — featuring improved filter media engineered by Ford for enhanced contaminant capture and support for extended oil drain intervals on newer trucks. The FL-2124S is the filter your Ford dealer currently stocks and installs.
This 12-Pack provides approximately 2-3 years of oil changes for a single truck (at 7,500-10,000 mile intervals) or one complete service cycle for a small fleet. Every filter includes a pre-installed seal ring for leak-free installation. The FL-2124S features a silicone anti-drain back valve rated from -75°F to 450°F, a pressure relief valve for cold-start protection, and heavy-duty steel construction with lock seam design and rust-resistant coating.
FL-2124S vs FL-2051S: Both filters share identical physical dimensions and mount — the FL-2124S is a direct drop-in replacement. The upgrade is in the filter MEDIA — the FL-2124S uses improved media designed to support the longer oil drain intervals recommended by Ford for 2020+ trucks. If you currently use FL-2051S, BC3Z-6731-B, or BC3Z-6731-A, the FL-2124S (MU2Z-6731-C) is the correct current replacement.

The improved media in the FL-2124S is designed to handle the higher soot loads and longer oil drain intervals that Ford now recommends for 2020+ 6.7L Powerstroke trucks. For 2011-2019 trucks, both filters work perfectly — the FL-2124S provides a marginal improvement in filtration life.

When to Replace
Replace at every oil change. Ford recommends 7,500-10,000 mile oil change intervals for the 6.7L Powerstroke under normal conditions, with the FL-2124S's improved media supporting the upper end of this range on 2020+ trucks. For severe duty (towing, hauling, stop-and-go, extreme temperatures, dusty environments), replace every 5,000-7,500 miles. Use 10W-30 or 15W-40 CK-4 diesel engine oil.
Why Choose the FL-2124S Over the FL-2051S?
If your Ford dealer stocks oil filters, they stock the FL-2124S — it's the current part number. The FL-2051S is still available from aftermarket sources but is no longer the factory-current filter. The FL-2124S costs approximately $5-10 more per filter but provides improved media that handles higher soot loads and supports extended oil drain intervals. For 2020+ trucks where Ford recommends longer drain intervals, the FL-2124S is the correct choice. For 2011-2019 trucks, either filter works — the FL-2124S simply provides better media for marginal improvement.
