Dave, this was NOT boring. More videos like these please.

I love this channel! I'm 17 years old and have been working at my grandfather's shop since 13. I plan on owning a shop one day.

Props to this guy the who is willing to say that he doesn’t know about his truck and is willing to listen learn and ask good questions
Never to old to expand your knowledge
Keep learning

Ford Senior Master Tech here and this is my recommendations. 1st and foremost read your owners manual and the scheduled maintance section. Ford uses what is called an IOLM for oil changes which stands for intelligent oil life monitor. The IOLM monitors many things to include engine load, vehicle speeds, temperature, regenerations events, etc to calculate when an oil change is due. Most of the time it is right around 7500 miles on a 6.7 diesel. I prefer factory filters since i have seen all the issues with cheap aftermarket filters. Highly recommend trans, diff, t-case svc every 60k unless severe use like constant towing then reduce to 30k. Fuel filters every 15k. All air filters every 20k unless real dusty conditions then drop to 10k-15k. Ford makes an excellent fuel additive that is designed to work with your fuel system and boost cetane and lubricity. I use it in my 6.0 diesel and buy it by the gallon to refill the single shot bottle which treats 35 gallons diesel, much cheaper that way. 1 gallon PM-22-GAL, single shot PM-22-ASU.

DEF fluid is 32.5% urea and i have not seen any real issues with different brands. Generally you will fill the DEF tank at every oil change. When the system goes into regen it is very important to complete the regen before shutting off the engine. Incomplete regens cause more issues than you can imagine. Diesel fuel is a crap shoot on quality and actual cetane rating. Here in Oregon it is crap compared to what is found in other states. Ford designs their engines off a cetane rating of 44 and here if you find 40 cetane your lucky. Just like gas there is summer and winter blends of diesel.

Boring? Heck listened to the whole thing it was so good. Thanks for taking the time to help folks like me keep our work trucks rolling!

Not a mechanic, but bought a2002 F-350 w/7.3L new, an old timer mechanic told me years ago, change your filters regularly, use marvel mystery oil in your fuel and oil. The truck just rolled 418, 000 mi. Still drive her every day!! Good luck with your new truck. Dave, another gem, thanks for doing these vids and sharing your knowledge, it is much appreciated. 👍👍🇺🇸🇺🇸

i just traded my 2014 F250. At 76, I am no longer in need of a diesel. However, it looked and drove like a brand new truck after just over 100k miles. I changed the oil, fuel filters and trans fluid on schedule and used Arch Oil products religiously. Never had injector problems or EGR issues. Regens were so infrequent that it was a big deal to see one. I also did not idle it for anything other than a traffic light and minimized short trips because diesels like to get warmed up and run - not stop and go or just to the corner and back. I listened to Bill Hewitt videos - did not know about you then. Loved the truck and hated to downsize to a Tacoma but it was time. No more RVs for me - had 5. I literally put more miles on my golf cart now in my retirement community than I do on my truck. Keep up the good work, you are a great source of how to maintain and fix automobiles the right way. I love watching these.

Morning Dave, I’m an F150 owner, gas engine, of course, but Dave, that is the prettiest truck I believe I have ever seen, thank you for taking the time to talk to that guy and let him ask some questions, even though I’m not a diesel owner, that was very educational on my part, but make sure tell that gentleman that is the most beautiful truck I have ever seen. Thanks for your videos Dave.

[chuckb]

I learned something new. NOT BORING AT ALL. Wish more mechanics were like you, Dave. Thanks.

[MrEDDER]

Bought my first diesel (2022 2500HD) your channel was my first stop!!

[myzrocks]

I'd love to see a collab between Dave and Gale Banks.

[seanwicks]

I love how down to earth, objective and informative you are, sir. Another great video, thank you

[gary_beniford]

Definitely not boring. I love hearing good advice in laymans terms from a trustworthy professional

[nealridgway]

Been a mechanic for about 6 year's now finished my first full engine rebuild today. Watching daves channel has helped me improve so much. So thankful for the content you provide.

Every thing you say is true. You missed one bid thing unless you need the power and your towing something all the time by a gas engine truck. We have some small trucks in the fleet. The ones that do light duty work are gas powered. The ones we work hard are diesels if you don’t work the new diesel pick up trucks hard, they are just a pile of trouble. Too much unburnt fuel in the emission system. The engines run too cold. The list of problems goes on.
Great channel Dave

Diesels are simple to maintain. Do not idle them for long periods unless it is in cold climates. Diesels are meant to be worked and they run the best when under a load. Unfortunately alot of people buy a diesel and use it for odd stuff and the odd haul etc. They are used for commuting mostly which is not what a diesel is meant for. The more a diesel idles the more regenerations it does because fuel is not being burned fully at idle. The more regens a truck does the quicker your DPF filter system will need to be replaced or have issues. When doing services make sure to use the manufacturer brand of filters or WIX. The reason i mention WIX is most manufacturers filters are made by WIX. Never had a issue using them and the micron rating is normally better than manufacturers. I am not a mechanic but i have worked in the field for years with trucks and heavy equipment. Talked to all kinds of mechanics and seen engines taken apart and seen what the failures were. Do the proper service intervals, make sure the fuel filters are done everytime, never run a tank empty, always keep the half to full. If you live in a area where you can delete the EGR and DPF then do it because that is 90% of these newer diesels problems. Also do not put a stupid tune on get a regular tune.

I appreciate you looking at your “fame” as a position of importance to help others. Not as a lot do to boost their ego. It means a lot. Happy Father’s Day Dave.

[JeffreyWaters-ep]

I learned more about a diesel with you than anybody I know, thanks!

[tinyskustoms]

My work just bought me a new F 350 SXT to haul our stuff around the country with. I'm DEF sending them a link to this video. Also, Ive been pulling trailers for about 40 years, Ive never had a truck so adept at doing its job as this 2024 F350. Total beast, and i am NOT a Ford guy. 10 out of 10 would recommend. Great video, thanks for sharing!

[danielberry]

I love watching a video, that genuinely makes me more intelligent after viewing. Great work Dave!
