Blending fuels

mpetersrx7 · 12-13-07, 02:40 PM

Hi guys and gals.

New to diesel as I picked up a converted FJ->BJ60 with a 3B naturally aspirated. Have been running bio on it lately with good success, and a few of us in Austin were thinking of buying a bio processor. I just wanted to explore all my options and read some on blending. I know this is fairly new states side but read that it has been going on for a while in Europe.

I have read some info on fuel blending and interested to hear if anybody on the board has tried any blends with good results.

Some I read included:
10 gal filtered WVO
2 gal karoseen
1 gal dino-d
0.5 gallon RUG <- what is this???
Cetane booster
Diesel Power/Amsoil Cold Flow Improver

Seems something like this would be much easier than making bio.

Thanks for the input,
Mark

Yes, it's a lot easier than making bio. I run a 20% blend of canola with ULSD, plus Acetone and gum turpentine [less than 1%] as additives.
Lots of info at:

I am considering the same thing once I get my 6.2 diesel installed in my FZJ80. The link above is good, there is a section called "solvent thinning" that should answer most of your questions. I will answer you question according to what I have learned through my research. How you blend depends upon what you are trying to do and the climate you are in. RUG is simply regular unleaded gasoline, it thins the best but you can't alot of it (the amount is debatable) but 5% should be fine from what I have read. Kerosene thins better than diesel. If you live in a cold environment you need to thin more. If you are planning on running on a blend with a totally unmodified car I think you would need even more blend.
First you have to start with really clean, dry WVO.
My system is going to use electric injector heaters (to help on cold starts) and an inline coolant heater and coolant heated filters. I am doing this so I can run a higher percentage of WVO. The car will start on slightly thicker fuel until the engine is up to temperature then it will thin out with the inline heaters. By using the injector heaters and possibly a second cycle of the glow plugs I should be able to start on the thicker fuel without any problem.
Hope this helps, post your results so we can all learn.

Rusty,
Thanks for your reply. That site does have some good info. If I remember correctly, are you in Texas also? What parts?

I will probably try some blending when the weather warms up a bit and maybe add a heated filter to my 3B.

Let me know how your blending works out and what type of blends you ar running.

Thanks,
Mark

I am in Texarkana, not too far from you. I am still in the process of getting my conversion done on my 80. hopefully it will get finished up over the holidays. My plan is to run it a few weeks on diesel while I am getting my WVO filtering system built, then slowly start blending, maybe start off just adding 20-30% WVO just to see what happens, then start adding more as my confidence goes up and I learn things and as the weather gets warmer.
Keep me posted as well.
Rusty
