now this may just be my imagination,but i swear i can hear the injectors popping off in my pick-up on the ulsd.but it seems quieter on b-90.but seriosly,it could be in my head.

Your engine probly seems quieter on b90 because it has less BTUs so it probly has a quieter diesel knock. Just my guess.

Biodiesel is a quieter fuel, its not your imagination. The higher ignition resistance might be part of the reason.
As for LSD and ULSD...
I haven't checked if my cardlock supplier is selling ULSD yet, but I know the LSD has been the norm for a while now. I did have a slight problem a year ago when my truck began stalling but some ATF cured that. I have not run any additive consistently since then and I have no other problems to date. I put about 50K miles on this IP so far and I'm not sure how many were already on it before I bought my truck.
My dad has a GMC 6.5 turbo (not PCM controlled) and he never used any additive. Seems to sputter for a couple seconds when it starts in cold weather but other than that it still runs as well as when he bought it several years ago. For those that don't know, the early 6.5s had the same IP as the ford IDIs.
I have not been too impressed with my economy so far, but at least it has held steady after all the econo-modding I did. Maybe MPGs will drift back up in the next couple years. I guy can dream, can't he?

I don't know if it's the truth but when the ULSD came out I read up on it a bunch. Now this might be all hype to get us all to fall for the stuff but EVERYTHING I read from "official" sources and not just word of mouth said the addatives in the ULSD would make the diesel BETTER for all fuel pump and IP's period, mechanical or not. However they also said it might harm older seals and we would lose 1-4 mpg. from the LSD.
Almost everyone I've talked to that keeps good fuel mileage records has lost 2 mpg from LSD to ULSD. They were also all Cummins with Bosch rotory pumps and P7100s, the later 24Vs and Powerstrokes. With a coupla' GM 6.5L T.D.s too.
I have NEVER added anything to the fuel that feeds my rotory pump Cummins and I can't tell the difference with any fuel I've ever used except for a mileage decrease everytime they change the composition of diesel.
My Dad swears he has less power in his '97 Bosch P7100 Cummins with ULSD. Mine isn't a powerhouse anyway so maybe I just can't tell the difference, it's only 160hp/400 ft.lbs. Dad's is 230/460 with a waste-gate turbo so maybe it's more noticeable at higher power levels.
Just thought I'd share my experiences.
Should be pickin' up my IDI this weekend, got my fingers crossed!
I still dont get how we can keep cleaner emissions by burning more fuel that gets less miles per gallon and less power out put. Seems to me that you would come out even on emissions again. our 7.3 engines were rated at 175 hp back in 93. I wonder what they would rate at now cause I don't think that sticker on the valve cover is acurate now.
Also, what does the sulfer in the fuel do to the environment when it is burned. I really don't know but would like to know what they are trying to protect and prevent. Is it smog, ozone, is it destroying plant life, globel warming, making some company super rich or what. Does anybody really know here on this forum? cause I sure don't. Is it as bad as the lead in gas from back in the day before my time and what make is so expensive to process as they "say it is"? "I think im being denied critical, need to know, information" here.
I still say ALL of this crap is so that the Federal AND State Governments can get more fuel/road/hwy TAX.
They get a tax PER GALLON, the worse your fuel mileage the MORE tax they get.
End of story, no one will ever convince me different!
Everytime we get "CLEANER" with FUEL we lose effeciency.
WE ARE GETTING SCREWED! BY: Opec and all the countries involved, oil companies, the Federal and state gov'ts and the insurance companies. Always have been, always will be.
Remember the BOSTON TEA PARTY! We need to have the "TEXAS TEA PARTY!"
This gov't is out of control and corrupt in just about every way possible. If you think there not, you've your head burried in the sand and I might have to join you just to keep my sanity and self control!
Well, sulfur is a pretty major component of acid rain....it goes into the atmosphere and mixes with water and CO2 and forms sulfuric acid. Not good. I'm pretty sure that's the biggest reason for going to the ultra low sulfur fuel.

i still think it's all just so much B.S.the gov't reacting to the tree huggers who are spured on by Al(manbearpig)Gore and the global warming crap that no 2 scientists can agree on.it makes my head hurt.i just want affordable fuel and good mileage!

ding ding ding!!!
we have a winner!!!!
this is the exact reason for reducing the sulfur content in diesel fuel.
this is not something the tree huggers came up with, it is an EPA thing.
and as bad as it sounds, i agree with them on this one.

Afraid so. Coal does the same thing. When the EPA has to decide between MPG or emissions, it s no brainer which way they will go. Although I still hope the MPG will still be of some concern to them.

HAHA. I never really got al gores MANBEARPIG off SOUTHPARK relating it to global warming until i read it in your post. Now I get it. He's super cereal!!
