Stupid Question
All these talk about reduced lubricity in the ULSD affecting excessive components deterioration in the fuel system bring about another concern.
I have ranch and farming equipments that are build in the mid 2000 just prior of the release of ULSD, I have not gotten any notification from the MFG or their field reps to say I need to put additives to enhance the lubricity in the fuel.
What happens to the trucks and equipments that are spec’d for the old diesel?
Are they also seeing the same problems triggered by ULSD?

My off-road vehicle is a Kubota. Kubota did issue a statement regarding ULSD in their engines. Their statement was 'Kubota believes that ... the POTENTIAL exists for customers to use ULSD in Kubota engines.'
They then followed it up with a statement of 'Kubota cannot be responsible for any fuel system component failures due to unappropriate fuel, INCORRECT LUBRICITY, or fuel additives used'.
I added the capitalization for effect. In other words, they think it might be OK, but they aren't 100% sure
You can read the exact statement here: http://www.kubotaengine.com/support/d_statementl.html
This all said, it is apples and oranges looking at the fuel systems in a CRD design like the 6.7 and a standard injection system like you would have in a tractor. The pressures and stresses on the high pressure fuel pump are immense compared to what is going on with your older off-road diesel vehicle. This puts more importance on proper lubrication.
The reports I have heard, and witnessed myself in my own Kubota, is a definite reduction in power moving from LSD to ULSD...I really notice when it is really lugging down.
I wouldn't be too worried about your off road equipment having major fuel system issues from using ULSD however.

I work on farm equipment for a living and all I can say is the new fuel (ulsd) is good for business.
Injectors sticking open and then compression blowing carbon and hot gasses back into the inj. pump. While it doesnt cost 10 - 12 thousand it does take the profit out of farming.
