low sulfur fuel
1 - 20 of 33 Posts
Close, it's 15ppm for ultra low sulfur. And yes, if you have a 2007 or later model, you can get a fine for filling up with low sulfur instead of ultra low sulfur. Kinda like getting fined when the po-po find out someone's been filling up with off-road diesel.
Hey, I wonder if the ultra low sulfur diesel is going to be dyed a certain color. I know off-road diesel is, and that's how to tell the difference.

I was told no 07 diesels after 12/31/06 at Ford by the GM at my dealer. dont know what makes are going to do, thats why I bought one this year.

I don't know how illegal it is, but running a higher sulfur diesel in an vehicle designed to run ULSD will screw up the emission systems the 07+ vehicles will have. The PM filter will gum up with the higher sulfur content. It would be like putting leaded gas in new car the is designed to run unleaded.

Running Low Sulfur fuel in an '07 will not necessarily "gum up" the Diesel Particulate Filter that will come in the future trucks. It will actually plug up. Low Sulfur fuel has enough sulfur in it to reduce the effectiveness of the catalyst in the DPF. The catalyst reduces the regeneration temperature in the DPF so that diesel soot, now known as Diesel Particulate Matter, can be regenerated (turned into gaseous CO2).
A highly active DPF will regenerate DPM at about 500*F. Sulfur in fuel will poison the platinum catalyst so that the regeneration temperature exceeds 600* to 650*F, making it more difficult to regenerate. If exhaust gas temps stay in the 800* to 850* F range, no catalyst is required to regenerate DPM.

Too funny! /ubbthreads/images/graemlins/biggrin.gif
Actually this is one of my areas of responsibility where I work. Underground mining was required to reduce miner's exposure to DPM in 2001. ULSD is one piece of the puzzle to reduce DPM. Everyone thinks they know about catalytic converters and how they rob performance, etc. They ain't seen nothin' yet. /ubbthreads/images/graemlins/biggrin.gif
In the near future, diesel engines will have Diesel Particulate Filters with more electronic & electrical controls that will allow them to continuously regenerate DPM regardless of EGT. Downstream of the DPF, another filter device will then remove all or most of the NOx. Look for Exhaust Gas Recirculation systems and dual turbos, all to meet emissions requirements.
The 3 & 4 positions chips we see now for performance could become a thing of the past. /ubbthreads/images/graemlins/shocked.gif

So what is the ULSF going to do to my 1999 7.3? Are we going to have to use an additive to make it run right? /ubbthreads/images/graemlins/shrug.gif

That is the $64,000 Questions isn't it? To meet ASTM specifications, diesel fuel will have to meet some minimum lubricity requirements. Do it yourself additives will provide that extra peace of mind that individuals may desire.
No earth shattering developments have come from engine manufacturers about additional fuel lubricity when ULS fuel is required. I can guarantee that you will see lots of snake oil salesmen and others who will get on the additives bandwagon and dupe as much of the public as possible. One positive aspect of bio-diesel is its higher lubricity and that it already is an ULS fuel. /ubbthreads/images/graemlins/biggrin.gif

I just returned from Germany from a 7 year tour and after burning euro-spec diesel in my truck for the same amount of time haven't had any problems with the injectors or any component of the fuel system. BTW, Europe has been using ULSD for quite a few years now without any problems.

OH YEAH WATCH YOUR MPG DROP.All the reports I have read said we can expect a 2mpg+ drop. Some of this may be made up by additives but who knows???

Well according to the EPA's website we have ULSD here in Atlanta now. I track my fuel millage with EVERY tank and I have NOT seen any decline in MPG. Have your sources actually used this stuff?

Okay...so I have to now run 15ppm fuel in my 96 7.3 powerstroke. Boy...does it suck!! No power and my mpg have dropped apporx 2mpg or better. I've been looking for a good additive. I'm thinking about buying some sulfer and havin at it! Bad idea. Anyway...has anyone heard if there is something I can put in my truck (besides bio-diesel...that's coming next spring)?

Ok, I know I'll get some fallout from this but here goes...I live in Mexico and am wondering if anyone knows what is hapenning with Mexico's diesel?
BY the way...the price of diesel is about $1.00 cheaper per gallon in comparison to gasoline so it makes my F-350 turn out to be about the same as a car getting about 26 MPG! Not bad, huh?

also bear in mind that you're pumping a winter mix of fuel now. That decrease in MPG might not be solely attributed to the ULSD that you're running. Something to keep in mind.
