My blend mixing and fueling station

Postby SunWizard » Mon Mar 10, 2008 8:44 am

I make blend in a 35gal. truck tank with a 13 gpm Fill-rite diesel 12v pump on top . I put winter Diesel in first (which I store up during winter in a 300gal. tank for summer use) which is from the pump 50% kerosene to make a thinner blend (why I use winter diesel), then I add the VO, then I stick the spout of the pump into the filler on the far end, and run the pump for a few minutes to get it well stirred. Then I have 35 gallons of blend ready to go in my "fuel station". Its best to do this with D2 and veg above 40F so it will blend better.

Once they are well mixed, they stay well mixed in my tests in clear jars at different blend % and for >4 months, even at temps as cold as 0F.

Blending right in your vehicle tank instead of in a tank like this "fueling station", its hard to ensure proper mixing before you drive your vehicle. At a small VO% it may not matter, but at higher % it matters since the VO is heavier and will settle to the bottom of your tank and you can be running V100 instead of blend.

If you don't live in an area where they sell winter diesel, or you don't have a tank to store it, you could buy kerosene for the blend, or use higher % D2.

This is my blend and my "set-up" which is not quite as fancy as most but... I do not have the luxury of "extra space" where I presently live.

L = litres
oz = Imperial ounces (not American)
cubie = the conventional plastic, cardboard-covered container that new cooking oil comes in.

15 L (528 oz) WVO 88%
1.8 L (63 oz) old gasoline 11%
*50 mL (1.8 oz) acetone 0.3%
*100 mL (3.6 oz) turpentine 0.6%

*these are measured by adding 2oz of turpentine and 1oz of acetone to every litre of old gas into a plastic jerry-can.

The gasoline and additive "potion" is mixed (shook) and transferred into 1.89L plastic juice containers. One of these containers is then added to every cubie of WVO oil, which is about 9/10 filled (about 15L). I mix the potion with the WVO just before I put it into the vehicle’s tank. I simply open the cubie, pour in the potion, close the cubie, and swirl and turn the container for about a minute, and then I add it to the vehicles tank. Swirling and turning the mixture is easier if there is some void space in the cubie, which I why I do not fill the cubie all the way.

I choose to not pre mix the WVO and solvent potion because I store my clean oil in cubies and have found that the gas smell permeates through the plastic. The gas smell bothers my neighbours and myself when I am transporting extra fuel inside my van while on road trips.

This set-up is not ideal but it works well for me and keeps my landlord from suspecting that I'm producing bio-fuel in my suite. I just have to remember to grab one juice container of potion for every cubie of oil while I'm on the road.

Results of my early blending tests don't look good, for my use anyway.

I took clean/dry vegoil, a sample of what I put in my truck. Settled in a jar at 70 degrees F for several days it was 50% clear and 50% cloudy with white solids collected at the bottom. I extracted the top 50%, the clear oil, and then replaced clear oil with winter diesel (that was at 47 degrees F). The now 50/50 mix was cloudy and as time settled the saturated oil settled to the bottom. The mixing of 70 degree oil and 47 degree diesel did not truly blend at all.

I heated the mix to 140 degrees F and it cleared and appeared to blend very well. I placed it outside with an expected low of 15 degrees F. This morning it had more solids than it had when first mixed, as one would expect dropping the temp if the diesel didn't really dissolve the saturated oil.

Allowing it to warm back to 70 degrees saw some of the solids melt, but it went back to the same amount saturated solids as when first mixed.

Adding 3% turpentine also didn't clear the mix at all.

I could mix the 50% top vegoil taking out at the beginning, but there is no reason to think that a diesel mix with that clear oil at 70 degrees, would still not be subject to having the solids settle out at cold temps at the same rate as when not mixed with diesel.

Further, I suspect an 80% diesel mix would still have the same solids come out of the 20% vegoil that would have come out of that 20% at the same temp when not mixed with diesel. And it would fall to the bottom of my fuel tank and be sucked up first by the fuel pump.

Until I know a way to keep those solids dissolved at below freezing, my blending for that little Land Cruiser is on hold.

The clear clean oil from my cold upflow processor is left to chill to below 50°F so any remaining PHO and fats not removed by the cold upflow then settle out. Then the clear oil off the top is mixed 50% with #1 winter grade ULSD or stove oil, and filtered through a canvas bag filter and a Quik 'n' Dri™ column to absorb any remaining moisture into a 30 gallon poly barrel. To 24 gallons of 50/50 mix, 6 gallons of jetB stale dated helicopter fuel is added. This mix is pumped through a 5µ cartridge filter into a 20 litre/5gal fuel container to which 4 oz of turpentine and 2 oz of acetone is added. This fuel mix goes into the vehicle tank and pump diesel is added for the concentration desired, based on ambient temperature. This is what fuels my Toyota truck all winter, as cold as it gets even into the minus 30s.

This system makes the separation process continuous:

Thanks John, I'll give it another try, I'm afraid out of all the oil I have, maybe 5% or less is clear at freezing.

Try to find a source of canola oil.

Right now I have a mix of everything. Down the road, hopefully within 3 years, we'll be growing our own canola.

I will be running my short tripper Mercedes 300D on WVO/RUG blend soon and am trying to find out the best way to mix it ( 30 gal or 55 gal barrel ) . I am concerned about potential fire / explosion if use my drill powered SBC pump or my or HF 12v impeller pump for mixing and pump the blended fuel in my vehicle ( sparks from brushes in motors of both ) . How safe is the stored blend (treat with the same "respect" as 100% RUG as to fire /explosion hazard ? )? . Discussion and recommendations are appreciated .

Correct. Use only explosion proof motors, no metal barrels or other potentially sparking materials.

Any suggestions?

Use air compressor outside away from building vents. In a well vented room where you mix the blend; use an air drill and a paint mixer bit. This is common practice in automotive repair and paint shops all over the world and you dont hear about them blowing up when spraying volital stuff like carb cleaners, paints, etc etc.

If your air compressor is gas powered you have even less issue.

Imagion you'd have more issue with the vapor from the RUG fuel can your pooring into your oil than you do with vapor from the post mixed Veg/RUG but Im not sure on that.
