I would like someone to verify this info that I got.

I took my truck to the dealership and the diesel mechanic (also drives duramax) said the oil companies were no longer putting the additive in the fuel at the pump and that every diesel starting in January 05 will have to use an aftermarket additive for the injectors. he said GM is pushing the use of Stanadyne for this.

Has anyone else heard about this?? Any written documentation supporting it?

I am calling him today and get more info about it.

thanks in advance

nevermind..found out myself.



Ok, just wanted to clarify about what I had said earlier about the Diesel fuels and all..

Just called the Diesel guy at GM... he says the EPA is going to remove the sulfer in the diesel fuel in January which will cut down on lubrication of the injectors. he said the LLY should be fine after running the current diesel or additive for 100 gallons or so, so the injectors break in. He said you shouldn't need an additive, but should not be any problems using one. I told him I still was using Stanadyne and he said that was just fine.



From what he told me this may be an issue for newer diesels not running the current diesel blend, but after using an additive for a while should be fine.

So what going to happen to my LB7 ? do i need additive or not for this new diesel?

You could always run B20 which is 20% biodiesel. Supposed to have great lubrication properties. Hell if I could get a tankerload as cheap as regular diesel I would run b100.

from what the mechanic said..he also drives an LB7.. if you have ran this current type diesel or an additive for 100 gallons you are probably ok. its just needed to break in the injectors properly on the newer ones.

He said teh LLY's shouldn't even need additive but does not hurt to use it. I already use Standyne anyways.

I would call your local dealer to be sure since most of my questions/answers were LLY related.

I wouldnt use B20 if your in cold climates this time of year.. I have a local customer that can tell you why.... after I pumped it all out and changed filter so he could drive truck.. Sludge city.. It gelled right up.

I havent heard of them removing the sulpher from the fuel, and I cant see them doing that. It is already low sulpher, no sulpher could be detrimental

i remember a time when they were saying that the lights would go out when 2000 came around. they didnt go out where i was at! could this just be a rumor?

I hope this is in fact a rumor.. I have been doing tons of searching trying to back this up. The only thing I have found is this.. on the EPA site.. wonder if the guy is off by one year..

EPA has regulated highway diesel fuel quality since 1993. As part of the Clean Diesel Trucks and Buses program, EPA reduced the level of sulfur in highway diesel fuel by 97 percent starting in 2006. Likewise, the Clean Air Nonroad Diesel Rule includes new fuel requirements that will decrease the allowable levels of sulfur in fuel used in nonroad diesel engines, locomotives, and marine vessels by 99 percent. Lowering sulfur in diesel fuel makes it possible for engine manufacturers to use advanced clean technologies which can be damaged by sulfur, just as lead was phased out of gasoline to prevent damage to catalytic converters. In addition, reducing sulfur levels will provide immediate public health benefits by reducing particulate matter from engines in the existing fleets of highway trucks and buses, nonroad equipment, locomotives, and marine diesel engines.

The sooner the sulpher is gone the sooner we will get the better (clean emissions and fuel economy) injection systems. Toyota might even bring us a full size diesel. Thanx Geo.

Actually what I read (and I'm trying to find it... it was somewhere on a petroleum industry website) was that the PIPELINE operators will not allow certain ADDITIVES in the pipelines after January so the oil companies will have to add it back in at the terminal. There should be no change in the fuel we see at the pump. I don't believe ULSD is mandated for another year or so.

Couldn't find the original article that I read, but doing a Google on "+pipeline +diesel +additive" yields lots of hits on the topic. Here's a link to a release from one pipeline company on the topic http://www.cioma.com/downloads/public/gr/Diesel_Lubricity_lttr_10.29.04.pdf

IIRC terminal operators will be adding equipment to inject the additives that are banned from the pipelines, so there should be no change in the fuel we see at the pump.

I spoke with our fuel rep over the weekend and he said that they are lowering the amount of sulphur in the fuel in 2006, but the oil companies already started to do this to be in compliance for next year. He also said that there is another environmental law that will go into effect in 2008 to reduce sulphur even more. This is only the tip of the iceburg according to him.

So someone tell me, is the lack of sulphur going to hurt our lb7s? do we need the suphur. what is it and what is it in there for ?

Sulphur acts as a lubricant in the fuel. You will probably need to run some kind of additive for more lubricity.
