And she just informed me that glass isn't allowed back into the house.She loves it when I do things like this.

...And a rolling emissions nightmare

I see no visible smoke difference. I figured by the time they truck it store it take it to the refinery, refine it and truck it back to the pump.. I'm probably putting out less emissions per gallon..lol as a side note, this being a military truck is emissions exempt. 4.56 gearing, no overdrive and 37 inch tires. 1 1/4 ton rating.. I'd be saved say the old girls probably still doing 13 or 14.

As if a 1980-something diesel Benz isn't already...I think that would be pretty sweet to burn crude! Send me a barrel!

Thanks for the picture. That is Awesome!

I just went out and moved the 300 d out of the driveway. I cannot believe how much quieter the cold starts are. I will get some more pictures of different grades of crude.

I will do that tomorrow.The Mercedes is getting the valves ran and some other minor work tomorrow. I will try to get a cold start video as well.

That is porter or stout. This belongs in OD?

I wanted to take a picture of the crude and forgot. So I went back to the well and drain some out of the discharge line into my Gatorade jug.normally I allow the oil to sit overnight to separate water out.by the time I had gotten home all the water had settled in the bottom of the jug even with movement in the truck. So it appears that the water separates out rather quickly. I'm going to take a small sample to work today to find the specific gravity of the crude.we have a small oil lab in our shop but I do not have signature cards for the chromatograph. I would like to see a component breakdown after it's been ionized. Our chromat is geared towards natural gas analyzation, but I may be able to look at percentages of sample on some key components.

When I ran my SDL on pure motor oil the car was so quite that it made NO diesel clatter whatsoever. It sounded like an industrious gasoline engine.

I want to see how my OM606 in my E300D reacts.

That's the way this one sounds on crude, almost as quiet as a gasser.

I am going to do a side-by-side comparison on diesel versus crude.. I thought I had a nasty fuel tank due to the long-term storage. I have been running it off a 1-gallon container under the hood. Now I can fill the tank with diesel, and switch to crude oil with The jug under the hood and do a comparison. I am a little confused on the fuel tank,the pre-filter was trashed but the strainer and tank was clean.

In the summer,I usually unplug my cold start advance on my military truck. I noticed with about 95% crude oil mix, what happened it really didn't like to start without the advance plugged in. I unplug them because I don't like the high idle on a cold engine. The Mercedes doesnt seem to mind which fuel you use or what mix. I have not studied the om617 injection pump, but assume there is no cold start mechanism.

I might add, my injection pump is set up as a multi-fuel. I learned that there is a compensator for fuel viscosity somewhere in the pump. I personally have never torn into a pump to see what is actually in there. The military wants to be able to run whatever fuel is available. I am pumping the wells today. but I will collect what I plan on running through the trucks before I pump so that there is not a water issue.I am going to collect an extra 5 gallons to run through a 1982 300D. It has been in long-term storage and I think the crude will give her a good tank of fuel to get broken in on. I asked my employer why such a big difference from well to well in the crude oil. Some contain heavier hydrocarbons, such as used in asphalt and Diesel production. Lighter blends of crude maybe minus the heavier hydrocarbon but contain liquefied natural gas that is known in the industry as condensate. We always called it drip gas. It is as clear as water when separated from the crude. My grandfather always ran it in the lawn mowers and such. Depending on the reservoir, the depth and location all caused different types of crude to be produced. So evidently all those dinosaurs rotted differently depending on several factors.

Sounds like you have some surplus Military Diesels. The Fuel Injection Pumps are made by what was called American Bosch now I think it is called AMBAC of something similar.

The part you are speaking of is called the Fuel Density Compensator.

The Fuel Injection Pump is a single plunger distributor type Fuel Injection Pump. The setup was for the military and there is various formulas as to how much lube oil pre gasoline or other fuel you could mix to try to get something similar to Diesel Fuel.

Back in the late 1970's I have rebuilt maybe 6 of the multifueled type fuel injection pumps. Note that they are more expensive to fix and your present-day BOSCH certified fuel injection shop may not have anyone who knows how to rebuild one nor have a line on parts because American Bosch is not the same as Bosch.
When you calibrate the pump you need to have a special adapter for the calibration machine that allows pressurized lube oil to lube the fuel injection pump and of course drain out of it. There is also a window on the adapter that allows you to watch the avengement of the fuel injection pump.
