i have just over 1800 miles on my 06 f250 cc psd. i have never put had a diesel before, and am very happy with it. whats up with the additives? doesnt ford not recommend them? and when and what kind of additive do you recommend? im leaving on a cross country trip from va. to ca. on the 7dec05, what should i do? additives?
The day I drive any of my trucks from the dealership I put Stanadyne in the fuel tank.
I suggest any name brand fuel additive that is locally available
I will merge, or someone will merge your thread here
I started day one and got 15 the first tank compared to 13.0 on my 04. I also drive a little different but haven't gone below 15 yet @ 2600 miles. It took 26,000 miles to get my cummulative avg above 15 on the 2004.
Non-alcohol baed fuel additives are OK. Read thru Tim's reference for info on a variety of products and discussion.
You can even do a search in the 6.0 forum on "fuel additives and really go nuts"
For the record....Ford does not recommend oil additives.
In any case, you can start using proper fuel additives now. IMO, the sooner the better.
Ford now has their own additives (PM-17A is cetain boost and PM-18A is anti gel). The Owner Guide in my buddies 2006 even has mention of these and use of non compliant additives may void a warranty repair. There is a group of us using the Ford boost and all are getting at least 1.5 mpg better and the engines run a lot smoother. I'm told the additive has lubricants that are no longer in low sulfer fuel.
IMO...If Ford considers other previously compliant fuel additives now non-compliant, it is incumbent upon them to notify each and every 6.0 owner of possible warranty implication.
They could use their safety recall strategy to accomplish this.
Especially if there is a threat of warranty denial on pre '06 MY and since they have published, via broadcast messages, that "Stanadyne and other quality fuel additives" are acceptable.
BTW: The other quality fuel additives have lubricity enhancements as well. Always have.
Domestic auto mfgs are very good at placing qualifiers in their product statements. Planting seeds of warranty denial fear. Much like they tried to do with oil and filters. Didn't say that you had to use MotorCraft, just that your warranty could be at risk if you used non-compliant oil, filters...etc.
