YES ANYONE NOT USING VEGGIE OIL OR BIO-DIESEL IN A DIESEL VEHICLE IS JUST SAD!!!! ITS FREE FUEL IF YOU USE VEGGIE OIL AND BIO-DIESEL JUST SAVES THE ENVIROMENT AND OUR ECONOMY!!!!!

What is the difference between No. 1-D diesel fuel and No. 2-D diesel fuel and can they be used interchangeably?
Always check with the manufacturer about the fuel requirements of your engine. However, both No. 1-D and No. 2-D are intended for use in compression ignition engines. In fact, in cold weather, No. 1-D is blended into No. 2-D or used by itself.
Three of the biggest differences between the two fuels are cetane number, heat content, and viscosity. The cetane number of No. 1-D may be one to two numbers below that of No. 2-D, but still above 40, the required minimum.

Since No. 1-D is less dense then No. 2-D, its heat content, measured in Btu/gallon, will be a few percent lower, leading to a similar reduction in fuel economy.

The lubricity of No. 1-D is likely to be slightly lower than that of No. 2-D because of its lower viscosity. Its lubricity is unlikely to be low enough to cause catastrophic failure. However, a steady diet of No. 1-D in equipment designed for No. 2-D may result in greater long term wear in the fuel delivery system.

The only problem is it smells a little and is against the LAW.

I thought MB IPs are all oil lubricated and not fuel lubricated??

aklim,

The lower, "crankcase" section of the IP is lubricated by the engine oil but the barrels and plungers, where the fuel is pumped, are lubricated by the fuel.

Thought I read something that said that we don't have issues with ULSD by Marshall Booth but I might be mistaken.

In any case, how damaging is it? Is there a way to determine for certain?

We often overlook Fuel Pump damage--Low Sulfur Fuels and bad fuel (85 300D) was another article I was looking at/

The "crude oil" pumped out of the ground is a black liquid called petroleum. This liquid contains aliphatic hydrocarbons, or hydrocarbons composed of nothing but hydrogen and carbon. The carbon atoms link together in chains of different lengths.

It turns out that hydrocarbon molecules of different lengths have different properties and behaviors.

The first four chains -- CH4 (methane), C2H6 (ethane), C3H8 (propane) and C4H10 (butane) -- are all gases, and they boil at -161, -88, -46 and -1 degrees F, respectively (-107, -67, -43 and -18 degrees C). The chains up through C18H32 or so are all liquids at room temperature, and the chains above C19 are all solids at room temperature.

The different chain lengths have progressively higher boiling points, so they can be separated out by distillation. This is what happens in an oil refinery -- crude oil is heated and the different chains are pulled out by their vaporization temperatures.

- The chains in the C5, C6 and C7 range are all very light, easily vaporized, clear liquids called naphthas.

- The chains from C7H16 through C11H24 are blended together and used for gasoline. All of them vaporize at temperatures below the boiling point of water. That's why if you spill gasoline on the ground it evaporates very quickly.

- Next is kerosene, in the C12 to C15 range, followed by diesel fuel and heavier fuel oils (like heating oil for houses).

heard it said that after you boil out all the other stuff you have diesel left. is that at all accurate?

so when this new diesel comes out we will have to put libricity additives into our old engines so we can run the low sulfur crap? i plan on running bio but im just cureous

I think there is tar and other longer stuff in there somewhere.

No, there is also No. 6 (Residual) Fuel Oil (Kerosene is No. 1, Diesel is No. 2). There used to be No. 4 and No. 5, but I don't think they make it anymore. No. 6 is used on ships and is referred to as Black Oil--it has to be heated up to about 140C and injectors are set to pop at about 270 bar on marine slow speed diesels.

I'm sure I've read (probably on this forum) that sulfur does not have lubricant qualities but that the process of removing the sulfur degrades the lubricity of the fuel.

Sulfur is a lubricant, see web site below:

More commonly called Bunker Oil...thick as honey at room temp....
