It replaces the Motorcraft FL1995 and is third-party tested to capture particles down to 25 microns at 99% efficiency. Built with synthetic media and a reinforced metal housing, the D4872 balances filtration accuracy with the flow capacity needed by high-torque diesel motors, whether you use conventional, synthetic, or blended oils.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the D4872 help extend engine life?\u003c\/h3\u003e\n\u003cp\u003eThe D4872 reduces abrasive wear by removing dirt, metal shavings, and other debris from engine oil before it circulates. Cleaner oil lowers internal component wear and supports more stable lubrication under heavy loads. While no filter guarantees lifetime protection, using a high-efficiency filter helps reduce the rate of contaminant-induced wear.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e25 micron filtration rated at 99% efficiency to trap fine contaminants\u003c\/li\u003e\n  \u003cli\u003eHigh-flow synthetic media to maintain oil pressure and circulation\u003c\/li\u003e\n  \u003cli\u003eRobust metal housing resists compression and damage during heavy use\u003c\/li\u003e\n  \u003cli\u003eCompatible with synthetic, conventional, and blended oils\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this fit my truck: which models and swaps are supported?\u003c\/h3\u003e\n\u003cp\u003eThe D4872 is made to fit Ford 7.3L Powerstroke engines produced from 1994 through 2003.

Doc's Diesel recommends routine changes aligned with your vehicle manufacturer’s suggestions and typical oil change intervals for diesel trucks. For many drivers, that means changing the filter every oil change or within the 5,000–7,000 mile window for heavier use and up to 10,000–15,000 miles maximum when following extended synthetic oil schedules and light-duty use.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFollow vehicle manufacturer's warranty and maintenance schedule first\u003c\/li\u003e\n  \u003cli\u003eTypical heavy-use interval: 5,000–7,000 miles\u003c\/li\u003e\n  \u003cli\u003eExtended-light-use with quality synthetic: up to 10,000–15,000 miles\u003c\/li\u003e\n  \u003cli\u003eInspect oil condition and service environment to adjust frequency\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat makes this filter different from stock options?\u003c\/h3\u003e\n\u003cp\u003eDoc's Diesel focuses on filtration media and structural durability to meet the demands of diesel service.
