blending VO with diesel

[Dannomanno]

Ok I am looking to convert my 85 6.9 idi to full vegi. oil, in time.... I wanna wait for warmer months to do any hardware work on the rig. For now I am lookin to run a blend of filtered vegi oil and standard out of the pump diesel. What I need to know is what a safe ratio is? It gets pretty cold in the winter here so I am thinkin to start at 80:20 Dieselil. Does that sound about right?

Also if anyone has any writeups on a 6.9 conversion and what that would take. I know I have to heat the oil tank, (gonna use my rear tank for oil), and run lines from rear tank to intake system, I think the rear tank pumps directly into the front tank when the switch is on?


So.... any help that anyone could pass my way on any of this stuff would be great! I have named my F-350 Dually "Fat Betty" and all fat girls should smell like fries!

in washington.....during winter......unheated tank.....blended...... I would not go higher then 15% veggie oil. You are going to get hard starts that are going to wear down your batteries and alternator. Remember you are not thinning the vegetable oil but instead you are thickening the diesel.

I've been thinking of doing the same. Another thought would be to use kerosene (at least to a small enough percentage). Say you run 15% vegi. Out of a 10 gallon mixture, instead of running 8.5 gallons of just diesel to 1.5 gallons of vegi oil, you might think of going 6.5 gallons diesel, 2 gallons of k-1 kero, then 2 gallons of filtered wvo. This way you are thinning the wvo so that this mixture wouldn't be thickening the diesel (at least not near as much).

Some people will have nothing to do with kerosene due to the dye and tax laws of off-road fuel, but I'm curious as to how much dye 2 gallons of kero would show up in a 10 gallon mix? I'm also curious how many non-industrial passenger trucks ever get their tanks dipped to see the color of the fuel???

Anyway, it's something to think about.


Erbilabuc, I have a question for you. I remember some time back you had tried the blending thing and it was a nightmare for you. I am only asking this to see what mixture you had tried. I remember looking at your fuel bowl and it looked like goop. Almost like fat. Was that a mixture issue? Basically I'm only asking to see if 15% would be safe and would help prevent the issues such as you had back then. Also, do you personally think that kerosene would help in the matter?


Sorry not meaning to hi-jack the thread.......

I mixed half 50/50 diesel/wvo in the cold southern california winter. I had Greasecar valve issues with the older s98 valves and I think it actually didn't pull diesel at all for 3 months and blended oil and diesel just sat in the fuel bowl. I'll say it again, when blending without heat you arent thinning the oil but instead thickening the diesel.

There are alot of guys using RUG to thin VO. RUG is much thinner the D2 or D1 so it takes less RUG to get the oil close enough to the same viscosity as D2. I used to think that blending especially with RUG was crazy but the more I read the more I think it does work.

But I would not recommend starting blending in the winter. I am pretty much convinced that I am going to try blending but not until spring & warmer weather.

Don't laugh--I was there in winter where it got to a bone-chilling 78F!

Gee, simone0414, am I starting to win you over?
