Thanks in advance.
You will find a lot of debate on weather cetane (the diesel equivalent of octane) boost is necessary. If you frequent any fOrd diesel forums, you will see it is a hot topic everywhere. The facts are
1. Ever since diesel requirements mandate lower sulphur there has been a big decline in lubricity available from diesel alone.
2. The Bosch pump in our Ford's was built to function within the European cetane values , which are a bit higher than those on average found in the u.s.
3. There have been some reports of fuel pump failure and the dealers have in many cases ruled that the cause was poor lubrication to the high pressure pump. (Note , this is not necessarily ford specific , but some are claiming issues with ford fixing them under warranty.)
4. The only 'approved' cetane additive right now for ford is the motorcraft brand.
Now with that said, I do in fact add 4oz of the ford stuff to every tank (7$ treats 125gallons or about 5 full tanks of diesel)....I have a GREAT relationship with my ford dealer and service dept. They know I run a slight tune and have always fixed my vehicles for warranty issues not BLATANTLY caused by my modifications or stupidity including my WAY modded 03 cobra....but I try and be smart about what's do and don't do...
Fwiw, my dealer has yet to see a truck with a hpfp issue caused by poor fuel lubricity.....for that matter, they tell me for the most part the only real issues they have seen with new diesels is software related.....not of the engine/tranny
Basically all I'm trying to say is there is a potential for lubricity issues using the fuel generally available in the u.s....and if using 7$ worth of 'booster' can save me headache, potentially boost power, and has no potential to cause harm to my 60k + investment then why not....
I mean I have never had an issue with a power surge,let alone ever seen anyone have one......but I have a surge protector on my trailer?
