How does this filter protect my 6.7L Cummins during everyday use?

The D16453 removes dirt, metal particles, and debris from circulating oil, reducing wear on bearings, camshafts, and other critical parts. Its heavy-duty metal housing and synthetic media keep filtration steady under high flow and load conditions common to towing and heavy-duty work.

• 25‑micron media tested at 99% efficiency for consistent contaminant capture.
• Heavy-gauge metal casing resists deformation at high pressures and temperatures.
• Designed for both synthetic and conventional oil types.

Will this filter fit my RAM 2500/3500/4500/5500 from 2025–2026?

How often should I replace the Doc's Diesel D16453 filter?

Change intervals depend on duty cycle, oil type, and operating environment; a common guidance window is every 5,000–7,000 miles under typical heavy-use conditions. Under lighter loads or when using premium synthetic oil, you may extend to manufacturer-recommended maximums, but always follow warranty and service recommendations.

• Suggested: 5,000–7,000 miles for heavy usage and towing.
• Maximum: 10,000–15,000 miles only if permitted by manufacturer guidelines and oil analysis.
• Inspect for leaks and seating at each oil change.

What are the construction and performance features that set this filter apart?

Doc's Diesel combines high-flow synthetic media with a durable metal housing to balance filtration efficiency and longevity. Components are selected to maintain service life under the elevated oil flow and heat of turbocharged diesel engines.

• Synthetic filtration media for high contaminant loading and flow retention.
• Robust metal body and reinforced end caps for long-term durability.
• Third-party tested to verify micron rating and efficiency claims.
