Doc's Diesel Filter Kit DFD4615+D6128 for 6.7L Powerstroke - Reliable

In this review of the Doc's Diesel Filter Kit DFD4615+D6128, the bottom line is simple: it is a practical, budget-friendly replacement kit for owners of Ford 6.7L Powerstroke trucks from 2011 to 2016 who need a direct-fit fuel/water separator and oil filter. The reviewer found the kit useful because it bundles both a fuel/water separator and an oil filter engineered with high efficiency 3 layer media paper, which is the single biggest reason to consider it when maintaining routine service intervals on F250, F350, F450 and F550 trucks.

Key Features

• Complete kit: Includes one fuel/water separator and one oil filter, so routine servicing requires one purchase instead of hunting for separate parts.
• Engine compatibility: Built specifically for the 6.7L Powerstroke 2011-2016 platform, ensuring the parts fit F250, F350, F450 and F550 trucks without modification.
• Filtration media: Uses three-layer media paper designed for higher contaminant retention compared with single-layer paper, helping protect injectors and the fuel system.
• Warranty compliance: Manufactured to meet and exceed typical manufacturers warranty requirements, which preserves coverage when using OEM-style replacements.
• Service guidance: Clear recommended intervals help owners plan maintenance: fuel/water separators every 5,000-10,000 miles (15,000 max) and oil filters every 5,000-7,000 miles (10,000-15,000 max).

Who It's For

This kit is aimed at DIY owners and independent technicians who maintain Ford 6.7L Powerstroke trucks from model years 2011-2016 and want an economical, direct-replacement option. It works well for fleet owners or private owners who perform scheduled service and prefer buying both a separator and oil filter together to save time.

Those who should look elsewhere include owners wanting dealer-only branded parts or specialty, performance-grade filtration options that advertise proprietary media or extended service claims beyond the stated intervals. Also, if you need exact OEM part numbers for warranty paperwork, verify compatibility with your service advisor.
