Hello folks.
Have we started the investigation into the effects of ULSD on the Detroit Diesel 2 strokes?
If you didn't know, all the diesel out on the road will be down to 15 PPM sulphur by this fall, so the new 2007 diesel's can meet the emissions standards. The new stuff will be running particulate filters too. And much larger rads, bigger again from the 2003 motors.
Also of note, there will be a new grade of engine oil to support the new motors, a multigrade that is low in ash, amongst other changes.
Anyway, highway diesel is 500 PPM now.
The fuel people will be formulating the fuel with a variety of additives. There is concern about lubricity, since the sulphur does do some of that.
If you didn't know, Detroit Diesel is owned by DaimlerChrysler, which is Mercedes, and by 2010 or 2012, their offerings will basically be Mercedes motors.
I haven't seen evidence that anyone is doing any testing to see the effects on all of us with legacy engines? (or is that historical engines?)
What says the congregation?
happy coaching!

SVO & WVO has NO Sulphur, Lurbicity factors can be added to the fuel tank easy enough. There's always a work around for everything.
I would suspect that someone would market an additive to specifically make up for the low sulphur fuels anyway. |

It's my understanging (though I could be mistaken) that WVO and SVO both have better lubricating abilities than standard Diesel. I hope so, as eventually I'll be running my MC-8 on WVO.

Supposedly, ULSD will have some additive for lubricity. I've heard they may use something like 2% biodiesel for this. The state of Minnesota already requires 2% biodiesel.
I've read that lubricity is not necessarily from the sulphur, but that the process of removing the sulphur reduces the lubricity.

Maybe this should be a new topic but what do you guys know or heard about synthetic diesel made from coal? and any name brands for additives for the low sulfer sufferers. |

This subject came up on another board a few months back. No one seemed to have an answer, so I sent off an email to Atlantic Detroit Diesel Allison and asked them about the ULSD. Although I can't quote exactly the gentlemans's reply, he said that New Jersey and New York transits have been using ULSD for over two years in the Detroit 2 strokes without any problem. I had a computer crash and lost everything or I would enclose the email. HTH.

The usual lubrocity standby for anyone concerned is a quart or two of ATF in the fuel.
Soltron and Howes and all the other goop mfg will no doubt create a product , weather its needed or not.
I have this fine bridge in Brooklyn ,
and for you can make a really great deal..............

With respect to lubricity, BioDiesel is a lubricant while petroleum diesel fuel is not, which why petroleum diesel has additives for improved lubricity.
I'm watching this debate on the ULSD fuels and hoping that there isn't a major issue with my bus engine. My wife and I recently bought a 1951 GMC PD4103 with a 6-71 in it.

It is my understanding that the Bio has less lubricity than Petro diesel. I have run B20 in my Mack truck, two DuraMax pickups, my Dodge/Cummins, Jeep Liberty CRD and VW Turbo Diesel Beetle. I have noticed no difference in mileage or performance. The Bio does have cleansing qualities which require initial filter changes. |
