I would think that with all the EPA laws there it would be absolutely mandatory that that's the only diesel sold there, and I thought LSD was no longer being manufactured in the US. Why would they refine two kinds if they can't sell it here legally?

The first station that I purchased ULSD from--pump marked ULSD--was an Exxon station. That tank of fuel, same driving conditions, 14 MPG. The next several tanks full were from pumps marked #2 diesel, driving condition still unchanged, 15.5MPG. Later, had to buy fuel outside of my regular pattern, so I went to a Revco near my work and filled with ULSD and you guessed it, the MPG's dropped like a rock. I can't explain it, but that's the story.

My fuel mileage dropped as well after the mandated ULSD came to pass.
My experience with the 6.0 has been to use (find) good quality Diesel, otherwise the fuel economy is reduced by as much as ~30%.
Now that I can only purchase ULSD I tend to stay away from low cost stations becuase I'll end up paying more on average.
BTW I also don't prescribe to those elickser fuel additives; there IMO a waist of money. However, I'm researching this and I may conduct my own control tests to see if they're worth the added expense.

I figure my motor was designed to run LSD, and now I cannot buy that, so a fuel additive that adds some of the properties missing in ULSD is a good idea.

I immediately found that the motor was quieter when idling, inside and outside the cab. Much less clackety clack. I figure that can't be anything but good, so I continue to use that product. I cannot say if it saves it's own cost in fuel savings because I don't drive enough repetitive routes to do a meaningful comparison. I would say it is doubtful, even though Walmart has mandated the use of DK in it's OTR fleet because their studies show it saves fuel. They are pressured to be green and go to extreme lengths.

Do they make an additive that will increase the engine noise level? I always like the clattering noise of a Diesel engine, especially when drivers pull up next to me, they have roll up their windows so that they can continue their cell phone converstaion while driving.
I've also notice that the amount of Diesel exhaust smoke has been reduced by using ULSD, which I've always enjoyed seeing the billow's of smoke permeate all those kind and friendly drivers that drive inches away from my rear bumper while flashing their headlights.

OK, heres my question. I have been running Bio the last 2 tanks and according to what I THINK I read it has more lubricity than regular fuel. Haven't driven it enough to notice any significant change but do I need to add the Power Service additive or am I OK w/o it? I guess it won't hurt to add it, but that $ will buy a couple extra gallons of fuel. Any thoughts? I will be adding the winter blend for the anti-gelling but do I need to add the summer additive?
