How Long Does a 6.7 Power Stroke Last? Mileage Expectations & Maintenance Tips

One of the most common questions from Ford Super Duty owners and buyers is: "How long will the 6.7 Power Stroke last?" The short answer is that with proper maintenance, these engines regularly exceed 300,000 miles. But the real answer depends on how you treat it.

With proper maintenance, a remanufactured 6.7L PowerStroke can deliver another 200,000+ miles of reliable service.

Average Lifespan Expectations

• Light duty / highway use: 350,000 – 500,000+ miles
• Mixed use (towing + daily driving): 250,000 – 350,000 miles
• Heavy commercial use (constant towing): 200,000 – 300,000 miles
• Neglected maintenance: 100,000 – 150,000 miles

The 6.7L Power Stroke uses a Compacted Graphite Iron (CGI) block that is significantly stronger than traditional cast iron. This material choice alone gives it a durability advantage over many competitors.

The #1 Factor: Oil Changes

Nothing affects engine longevity more than oil change intervals. Ford recommends oil changes every 10,000 miles under normal conditions, but most diesel mechanics recommend every 5,000 – 7,500 miles, especially if you tow regularly.

Use the right oil:

• 10W-30 (2011-2016)
• 15W-40 or 10W-30 (2015+)
• Must meet Ford WSS-M2C171-F1 specification
• Motorcraft or equivalent quality filter

Critical Maintenance Schedule

What Kills 6.7L Engines Early

1. Skipping oil changes — the #1 killer of diesel engines
2. Ignoring the CP4 fuel pump — not using additives or a lift pump
3. Running low on coolant — leads to EGR cooler failure and overheating
4. Excessive idling — causes carbon buildup and glazed cylinder walls
5. Ignoring warning lights — small problems become catastrophic failures
6. Using wrong fluids — incorrect oil, coolant, or DEF damages components

When to Consider a Remanufactured Engine

Even well-maintained engines eventually wear out. Here are signs it's time:

• Oil consumption exceeding 1 quart per 1,000 miles
• Persistent blue or white smoke
• Loss of compression (rough running, hard starting)
• Excessive blowby from the crankcase vent
• Multiple system failures occurring simultaneously

A remanufactured engine can give your truck another 200,000+ miles at a fraction of the cost of a new truck. Our remanufactured 6.7L Power Stroke engines come with a 1-year unlimited mileage warranty. Get a quote or call (631) 991-7700.

Conclusion

The 6.7L Power Stroke is built to last. With disciplined maintenance — especially oil changes and fuel system care — there's no reason your engine can't reach 300,000 miles and beyond. And when it does eventually need replacement, a quality remanufactured engine is the smart way to keep your Super Duty working for years to come.

When It's Time for a Replacement Engine

Even the most well-maintained 6.7L will eventually need major work. When that time comes, a remanufactured engine is often the smartest investment:
