I wanna know how bad the ultra low sulfur fuel really is
So here's the deal
I have heard from several people (but they have no credibility in the fuel world) that this new diesel fuel is really dry and causes the rubber to shrink in the engines ect. They say that this fuel is very dry and will eventually ruin our motors and never run a diesel without running an additive now. But when i ask them where they got this info is some story like...well this guy i know down at the diesel injection pump place says so b/c they have seen sooo many pumps come in from this and the seal are all bad.
On the other hand I think I read it here a long time ago but they story was told that the new fuel isn't bad and has the same properties as the old and that the new fuel has the additives put back into the fuel so that it's not so dry ect. I want to see hard facts about this fuel. I don't want any lameo story about your friends buddies dog's lover that happens to work for opec. I want something that i can read myself and see what makes up this fuel and we shall put this to rest one way or the other.

I'll go out on a limb and say that there isn't a single rubber component on my 99 7.3 that if it failed it would take the motor with it. I've had about 5-6 fuel leaks for various reasons over the years and most were rubber related (ie drain valve o rings).
I've even sprayed diesel on the downpipe without incident.
Sorry I don't know anything about the sulfer in diesel other than to say I've driven over 200,000 miles without using additives and have had one injector failure in that time frame.

In the "older" engines which used 500ppm sulfur fuel then I definately would use a fuel additive as these was not designed for a 15ppm fuel and other lubricants (in today's fuel from the pump) which might protect you. I have several older engines and use B5 soyfuel and they run just like the high sulfur fuel. I ran out once and had to get some normal fuel. It didn't like it at all. Wound up dumping a lot of fuel additive into the fuel.

I am in NorthernNJ and it will be a 6.4 when it ever arrives. I just want to be well informed before in advance of taking delivery. I understand that maximum of 5% Bio-D is allowed with the 6.4's.
ulsd has the same lubricity as lsd and hsd, thats the reason it is more expensive, lsd and hsd used the sulfer to lubricate everything, when going to the ulsd they have to refine the fuel more and add synthetic lubricants to the fuel to replace the sulfer. your truck is safe, it will not blow up because of ulsd, all you will see is a slight drop in fuel economy and horsepower. the ulsd doesnt burn as hot as lsd and hsd
Funny, decades ago I remember that Mexican Crude oil was not wanted as the sulfer content was high, and they said sulfer was something they did not want in diesel fuel!
Now they say it's needed as a lubricant?
And how much sulfer is in BioDiesel?
I would guess none.
And if BioDiesel lubes better than DinoDiesel, then they should use BioDiesel as the aditive to help lubricate rather than Sulfer or other chemicals!
Had to sell the Gray 1991 F250 standard cab, 7.3, E4OD, 3.55:1, stock wheels and tires.
It had a verified 19 mpg city taking off slow as hell then shutting it down at red lights, and with the radiator grill blocked flush, no bed cover, "drag shoot" mirrors still on I got 24 mpg at 50 to 55 mph on the freeway empty!
