Has anyone found out about the new diesel fuel , will the older diesels we been running on LSF be able to use the new fuel without harm? thanks

 

ULSD has been being weened into the supply since June 06. there have been an increase in oring leaks but nothing that points to the ULSD more than just time as being a likely cause. The cetane and lubricty levels are in spec for our motors but personnaly I notice a better running motor when adding 16oz diesel kleen to every tank.

 

thanks Alan for the info, I will start using diesel Kleen, I have seen it in the walmarts in the white container an also the silver looking container.

 

Diesel Kleen is in the silver jug. The White jug is winter time anti-gel.

Try some bio-diesel. I've been using B-20 (20% bio-diesel/80% dino-diesel) for a couple months now and love it. The Bio is a natural cleaner and lubricator.

Get bio if you can find it

 

Howard, where do you buy the Bio? at walmart ? or will the auto parts stores have it ?thanks alot,

Tom

 

Nope. You get it at fuel stations or through co-ops. If your really ambitious, you can make it yourself. Go to the bio-diesel forum, there's guys there that know a lot more about that stuff than I do.

you could probebly search for stations that sell bio-diesel near you, try google searching it.

is this a good search? i just found it now.. ??

 

thanks 2002f250, this just what i need and there are serveral in my area

 

Cool, just realized there is one in the town next door... about a 2-minute drive from my church... but they're only open Monday through Friday. I'll have to make a special trip (only 15-20 minute drive or so) and try out some bio diesel for the first time.

 

Consider yourselves lucky the closest bio I can find is a 300 mile round trip.

 

Here is a good article... http://thepowershop.com/index.php?pr...owsulfurdiesel
ULSD is a 15 parts per million of sulfer form 500ppms. sulfer is a natural lubricant and our direction injection need it. Euroup has had ULSD for years BUT they have mandates that require lube to be put into the diesel to raise the lubrisity. USA dosn't and with a diesel you got compression and injectors and without that you don't have dieseling. Without lube you got no injectors so we have a problem. The new stuff hold more water and out "water in fuel light might not be able to detect it. Our injectors will boil in seconds and they are not cheap to replace. I DO recommend using a addivtive like stynadine!

 

Darn good information Mikeysnapper! I'm looking into this stanadyne now. thanks

 

It's not exactly the lack of sulfur that causes ULSD to loose lubricity, it's the scrubbing process itself that removes the sulfur is what strips out the lubricity.

Also for ULSD to meet national highway standards, a lubricity additive must be put in the fuel before it reaches the pumping station. It's added by the fuel companies at the distribution level. So ULSD already has lubrication sufficient to meet the requirements of current diesels on the road. This same process was done with LSD as well, so it's nothing new.

Water contamination happens at the pumping station. Stations that sell less quantities of diesel will more than likely have a greater risk of contaminates in their fuel, simply due to the old fuel just sitting in the tanks.

The biggest problem with ULSD is that o-rings do not swell as much with the new fuel. IMO, this is leading to a rash of fuel drain o-rings leaking in the fuel bowls lately on our trucks. That looks to be the weak point in the fuel system on the 7.3L.

There are better articles out there to explain ULSD. Read up on a few and you'll understand that it's not going to be Armageddon on your engine.
