I’m picking up a 2013 F250 6.7 4x4 tomorrow or Wednesday. It’s my first diesel, something I’ve wanted since I was a kid!
The truck is still under warranty, so any DEF/EGR deletes will have to wait. What should I keep an eye on as a new owner? Any tips are appreciated!
Ford diesel tech here.
First, never EVER put DEF in the fuel tank. If you do and turn the key, it’s a minimum $10,000 fix.
Watch out for code P207F as your truck gets older. It’s tough to diagnose, and Ford might recommend replacing the NOx module or the SCR system (exhaust filter). It’s a common pain point.
Keep up with fuel filter changes, as a clogged EGR cooler or bad EGT sensors can cause issues. Also, aftermarket air filters can lead to regen problems. The 6.7 can be picky like that.
They’re solid trucks overall. Once the emissions stuff is deleted (down the line), you’ll likely have fewer problems. Let me know if you have any specific questions!

I’ve seen people put DEF in the wrong tank twice in two months. It’s a nightmare every time.

How do people even make that mistake?

I have no idea, but trust me, it’s awful to deal with.
Check for frame rust—always a concern with older trucks.
The 6.7 is much better than the 6.0 or 6.4. If it’s still under warranty, hold off on any deletes for now.

Deleting emissions components like DEF or EGR can void a powertrain warranty, but it won’t affect body, frame, or ABS claims. Just something to keep in mind.
Basics: don’t put gas in it, and change the fluids and filters on schedule.
If you don’t know when the last oil or fuel filter change was, go ahead and get them done for peace of mind.
The fuel system is sensitive, so change the fuel filters with every oil change or every other one. A clogged fuel filter can lead to a $10k repair.
Keep an eye on the fuel/water separator and drain it regularly. Older turbos on these trucks can fail around 80k miles, but plenty make it past 300k.
If you accidentally put gas in the tank, don’t turn the key. Tow it and have the tank drained. DEF contamination is even worse, so be extra careful.
Overall, these are very reliable trucks. Enjoy your 6.7!

I’ve seen gas drained successfully and the truck restarted with new fuel filters, but if DEF gets in there, it’s game over.
Be prepared for higher maintenance costs. Diesel repairs are expensive, especially for Fords. The fuel system is sensitive to water and dirt, so use quality filters and change them regularly.
If you don’t tow heavy often, you might have been better off with a gas engine. But if you take care of it, the 6.7 can be a great truck.

One more thing—don’t assume it takes 15 quarts of oil like older models (7.3, 6.0, or 6.4). The standard 6.7 takes 13 quarts, per Ford’s workshop manual.
