Can anyone recommend the use of cetane booster ie KLEEN DIESEL
in the new 6.7 liter engines ?

 

I use Power Service Diesel Kleen in the white or silver bottles but when it gets colder I use the red bottle. If you have any doubt I would just run the motorcraft stuff. I have used that many times as well.

 

Yes. I highly recommend it.

 

I have used the Motorcraft stuff for years! Great stuff...

 

I have read several posts indicating that no fuel additives are necessary for various reasons. Having just had $12K+ of repairs done to my 2012 F250SD, I would argue that point! As someone did point out, diesel fuel is "supposed" to have lubricants added at the refineries. Operative word, "supposed" to! And as pointed out, this is a crap shoot as to whether or not it is done, or done to the correct levels.
The issue here is that if the lubricant values are not correct, the High Pressure Pump WILL NOT be sufficiently lubricated, and as in our case, COME APART and send metal shaving throughout the fuel system, including the injectors which = NO BUENO!
Again, $12K+ in repairs, that included new injectors, rails, lines, filters, HPP, and the fuel tank removed and decontaminated. 9 days in the shop as they had to wait on parts.
So yes, to be on the safe side, I can say the fuel additives ARE REQUIRED. Of course Ford would only recommend Motorcraft products, etc , so do your research and use what you feel is best for your driving conditions!
Good Luck!

 

my last 5 diesels (the last 2 with the 6.7) I've not added anything,
but it's your truck so I'll let you make that call on your vehicle

I just make sure I buy diesel from stations that turn over a lot of diesel, mostly national chain with deep pockets and ALWAYS save the last months worth of receipts (just in case)

 

Any more details about this? What happened? Covered under warranty, ESP, or Auto Insurance?

 

The thing those additives are most effective at is separating you from some of your hard earned cash.

Maybe run some anti-gel if you have #2 diesel and the temps you will be operating in won't be above zero, but the rest is useless for the most part.

 

This damage was covered by warranty. The "thought" was that due to decrease lubrication in diesel fuel, or at the very least, the inconsistency in the levels of lubrication, hasn't/isn't taken in to consideration in the production of the HPP's. VW has a law suit pending against BOSH, one of the largest manufacturers of the HPP's due to this matter. ALL the manufacturer's ARE aware of this issue. I have purchased my fuel at the same chain since I bought the truck w/ the exception of a hand-full of times. Again, it's a crap shoot, even with the "major" stations as the lubrication additives is done at the refineries and it may, or may not be done to "specs", if there are any. It only takes one bad tank apparently to ruin your day! Of course, the first thing they look for was water in the fuel, but that was not the issue.


And after several "discussions" with the service center and the Ford DM, basic warranty extended an additional 5 years / 75K miles, plus I have the Premium service plan. So yes, it sucked, but feel Ford stepped up and took care of us.
