Good afternoon gents. I just pulled the trigger on a 2015 6.7 with 22K miles. What are the best things I can do to keep this thing running great for years to come? I owned a 6.0 from '08 to 2014 and it was easy to find the things to do to increase reliability with that motor but I'm finding it harder to find with the 6.7. I guess that's a good thing. So other than regular maintenance what are some things I can do that will help. Thanks.

 

Welcome! And pics or it didn't happen!! One thing about these trucks is that they are peculiar about Ford filters. Use only Motorcraft for all locations. Most of us buy from https://www.dieselfiltersonline.com/

Some of us change the oil at 5k miles regardless, some of us let the truck tell us when to change it. As far as oil types, it must be the CJ-4 oil, which is getting harder to find unless you buy Motorcraft oil like I do at Walmart. I run 15W-40 here in the south, but guys all over run full synthetic 5W-40 with no problems. I'm sure that you've heard of the "REGEN" with these trucks. The 6.7L handles them much better than the 6.4L ever did. Try to let the "Cleaning Exhaust Filter", which means it is in regen, finish. Most of us either have an Edge monitor, Torque Pro app, or someway of watching the vitals of the engine. I do not use a programmer as this thing does all I want it to with power to spare.
As far as reliability, these things are as reliable, if not more, than any other Ford diesel engine even the 7.3, just more gadgets. Plus, it's power and torque are INCREDIBLE. Most of us use a fuel additive of some sort. Either Ford's PM-22, Power Service's Diesel Kleen(Gray for warm weather, White for below freezing), Stanadyne, or one such as these.
I recommend you read the 6.7L tech section of this forum and it will fill in many gaps to the questions you or I haven't even thought of. These things are fantastic and real joy to drive. Even more fun to tow with!

 

I didn't know about letting it finish the regen. It started when I almost got to work so I'm assuming it didn't finish. How long does it take to finish? Like 20 or 30 minutes. I was also searching for a way to check the status of the regen, whether active or not, but couldn't find it. Is it only possible with a programmer or monitor?

 

Sometimes it is virtually impossible to let them finish due to time restraints, but you can stop it by getting where you are going, putting the truck in PARK and letting it idle for about 30 seconds. This stops the regen and therefore will not put unused fuel into the oil pan. The 6.4L was much worse then these. These are good.
As far as the monitor, you can use your smartphone with the fore mentioned app, or I use the Edge monitor. I can watch all the temps and pressures at at glance right on the base of the windshield.
IF you are going to tow heavy or often, I would like to recommend an H&S Cold side intercooler pipe as the stock one will eventually rupture under pressure. Rodney(Karl4cat) and I have both had failures at pretty much the worst possible time other than climbing a mountain. There are threads on them here.

To answer your question about how long a regen takes. It varies, but around 8-10 miles on the highway.

 

Thanks for the replays guys. I appreciate it.

 

So I was browsing through the information center and noticed DYE Calculation. What is this?

 

DTE?

Distance to empty

 

On the motor oil......As long as the designation inside the seal says CJ-4 you 'should' be ok.

API has made a change to CK-4 oil for diesels. Per the API, CK-4 oils are backwards compatible so they are also CJ-4 approved but.......

Ford has issued a position statement regarding the use of CK-4 oils and developed a oil specification (WSS-M2C171-F1). Ford has 'approved' some of the CK-4 oils.

See here for position statement & list of approved oils.

Thank you guys for all the help. I'm sure it won't be the last time. Lol

oh and the the pics, here they are

 

Another white one, yeah! It is my contention white trucks get better mileage.

 

After 27 years of owning only black vehicles, then one Royal Red which led to my Tri-Coat Platinum White, I can honestly say that the white trucks are cooler Take that any way you want!!!

Good looking truck by the way!

 

They also don't show the dirt nearly as bad as the darker colors. I love black but refuse to be a slave to my truck so Platinum white it is.

 

I can't stand the Oxford white but the platinum tri-coat is my absolute favorite color and this is actually the first white truck I've owned. It's a CPO and managed to get the dealer to increase the warranty to a 7 year 100,000 bumper to bumper. They tried to tell me I had to buy the warranty to get a better interest rate so I started to walk out after I was already in finance. Apparently they weren't having that. Lol

 

That's a nice thing to know. Where did you discover that piece of information. On here? I usually just keep driving a few more minutes. Unless I'm late to work.

 

Welcome ! You will love the 6.7 and this forum. Good folks glad to help.
