Nelssen,
I don't know about the ULSD stickers on the pumps. I've never looked for them.
Most of the fuel I get is from the Flying J at 67 Ave. & I-10.
I got this information at a seminar given by the Bosch Rep. from the Las Vegas Bosch repair facility. He said, last year, that a lot of the diesel distributed on the West Coast is manufactured in CA. The only fuel they manufacture there is ULSD.
We are supposed to get diesel from CA & TX, in the Phoenix area. I believe the majority of it comes from CA, which, would be ULSD. I really don't know what TX is sending us. I know they have been manufacturing some ULSD in TX.
At last years May Madness, where I attended the seminars, the Bosch Rep said that if we were living anywhere near the West Coast, there was a good chance that we were being serviced with CA, ULSD diesel fuel. He went on to say that Bosch Hdqt's had sent a bulletin to all their field offices warning them that they were seeing an unusual number of fuel delivery system failures that could be directly related to the lack of lubricity in the ULSD. The recommendation was to use some sort of fuel additive that enhanced the lubricity of the fuel.
At this years May Madness, we were treated to another seminar, given by the same gentleman. He made no mention of the need for additional lubricity, at this time. After the seminar, I asked him if there was still a need for the additive. He said that from what they have seen, the low-lubricity problem has been addressed, by the fuel manufacturers, & that it is nowhere near as critical to be using a lubricity additive.
Another interesting thing he had said, last year, was that if we lived near a military installation that had jet powered aircraft, that it would be a good idea to fortify our diesel with a lubricity additive. The reason was that jet fuel is a very dry form of diesel that has to be very pure for the military to use it in their engines. If it is contaminated with any #2 diesel fuel additives, the government refuses delivery & that fuel is delivered to the local diesel fuel market for distribution to us. They add additives to make it compatible with #2 diesel but, how do we know that the tank farms put enough additive in the jet fuel or if it was spread evenly through the entire load of jet fuel.
Bosch Hdqt's had noticed an increase in fuel delivery system problems that they were able to trace to inadequately lubricated jet fuel that was sold to the general public.
As you know, we have Luke Air Force Base located on the west side of the Phoenix Valley. So, we have the potential for the same kind of problem.
Personally, I'm choosing to run an additive just to be on the safe side.
