If you own or plan to buy a truck with a Powerstroke 6.7 diesel engine, no doubt you have questions about what it can do and how long it will last in comparison to other engines. Ford first created the Powerstroke 6.7 in 2011. The new design rejected HEUI injectors and adopted a common rail injector design. Ford added a GT32 SST single sequential turbocharger and four valves per cylinder too. The original engine boasted 390 horsepower and torque of 735 lb.-ft. then. Newer engines now flaunt more than 475 horsepower and 1,050 lb.-ft. of torque. That’s a lot of power, so make it last. If you’re wondering how many miles a 6.7 Powerstroke will last, here are the basics.

Listen to the Manufacturer

In general, 6.7 Powerstroke diesel engines are known to reach 200,000 miles or more with only the most basic repairs along the way. However, some engines have racked up 400,000 miles or more with proper maintenance. We advise checking out your car manual first to see what sort of maintenance schedule is recommended by the manufacturer. Sometimes the most obvious advice is the best advice. Also, unless you’re a skilled do-it-yourselfer, bring the truck to a recommended professional to ensure its basic maintenance is handled properly.

Check the Oil

Many if not most engine issues can be traced back to the oil tank. Regular inspections and oil changes are a must, of course. Some experts recommend using 10W-30 oil for everyday usage, or 5W-40 for situations where the truck faces more challenging driving, towing, and other conditions. It is recommended that you change the oil every 7,500 miles driven, but again, check the manufacturer’s recommendations or discuss what’s needed with your mechanic.

Filter Tips

When you get the oil changed, always check the truck’s assorted filters, especially the air filter. When your truck takes in air, the filter ensures it’s not sucking in dirt and debris as well. By that same token, keep track of your fuel filter’s condition; it prevents bad stuff like rust and soil from getting in. Keeping your engine clean ensures a longer life span. In general, replace your fuel filter with every third oil change, but check with your mechanic and watch for signals from your truck to see when it’s time for a new fuel filter.

Don’t Blow a Gasket (Literally)

Historically, some Ford diesel crate engines have had issues with their head gaskets. Again, regular maintenance alerts you to worn-out parts and diminished service. Head gasket failure is kind of a given for some truck owners, so keep an eye on your gasket. Look for leaks and evidence of leaks, particularly around the coolant pressure cap. If your truck displays signs of head gasket failure, go easy on it until you can get it to the shop. But don’t wait too long.

With these suggestions in mind, the answer to the question how many miles will a 6.7 Powerstroke last is…a lot, and maybe even more than that!
