1st add an extra CAV filter for immediate blending while the grease kit is assembled.

Slip the grease into me baby; I'm ready... for a blend anyway. What I have done is placed a CAV filter $46.50 in front of the uplift pump and repositioned the mercedes disposable primary filter before that.

So it goes primary filter - CAV filter - uplift pump - original MB filter - IP

First Greasy kiss and acceptance of bodily fluid being blend of 80% WVO (very clean clear well settled Canola) 15% Kerosine and 5% Ethanol (methylated spirits AUS).

Not yet set up to wholesale dewater but the WVO from the same source has been consistently dry when tested. I didn't test this batch but am putting my IP where my mouth is and adding the Ethanol...

This will have the effect of course of lowering the available power slightly....

Filtered to 5 microns (I think) won't know until I get my commercial 5 micron filter bags...

Well the Geasy Pig has now done 1000 kms on the stuff except for having 20 litres of Dino it was all kugel a la Canola WVO/Kerosine/Ethanol/water at 80/15/4.75/.25, about 120 litres of it. The GP was workin hard in 30 degrees centigrade and over towing a trailer with 350 litres of oil in it plus toolbox water etc etc etc. Plus its a new moter with rings yet to bed. The jar I put some sample in still shows no separation and I have got no water in the Filter trap.

Out west where I run the GP to its so hot I would not need to heat canola. The injector lines are too hot to touch...

No filter change needed so my filter bag is working to remove those pesky HDLs that I now believe gave me trouble in the Nissan.

BP,

This sounds very promising to me. I have never considered adding ethanol to a blend...even though my state is a huge ethanol fuel producing state. Please keep us posted as I hope to approach a local ethanol co-op to see if they are interested in running similar blend tests.

With the price of Diesel rising fast this spring I bet the farmers that own the co-op will be interested in doing something to lower their fuel costs. One already has converted several fo his tractors to wvo..so I have an "in" there.

Would you mind if I started a new discussion thread on your ethanol blend testing? I think it deserves its' own.

Yeah I guess that's OK and I assume you do not want to carry it on in your dewater thread? I didn't mean to gainsay you there I was just injecting the idea.

Neutral has some very positive ideas on it too..

I'm wondering if it will stand the test of cold though and just how much we can dissolve...

Hey BP...
I just think it has promise and that we should make it easier to find in the future rather than buried under a heading that doesn't really describe it.

I use a mix of 80 % WVO, 15 % Diesel and 5 % IPA (isopropyl alcohol ) since 6 or 7 years.
I filter my WVO to 1 micron . Cold, no heat.
Only then I use it for my 1-Tank Conversion.
The mix remains stable. It does not separate.
For my 2 Tank-Conversions I am less picky.
I use heat and accept that animal fat passes through the filters.
But I always go for the mix mentioned above.

More important for me is I never had a defective pump.

In Germany it is also called Schur Mix
( Schur Eco Fuel for reference )
The inventor Mr. Schur did his first experiments app. 1995.
Prolonged tests were done from independent motor companies. Very satisfying.

Even it is in German I want to mention the link http://members.aol.com/hpschur/raps.html.

During my time in Germany I was involved in HPLC. ( High Pressure Liquid Chromatography )
Pressure range up to 180 –200 bar ( atm ).
If you multiply it x 15 you gett psi.
Two pumps were used to run a gradient .
One containing water, the other methanol.
The pump containing water leaked regularly and the the seals went because of friction.
The pump containing methonal , or ethanol or isopropanal needed much less changes.
Alcohol lubricates.

Wow; and have you any estimates of how much water might be in your mix?

Do you dry the WVO first? Do you know if it contains appreciable amounts of water?

Dana how do I trnsfer posts from one thread to the next?

No, I have no way of telling.
I collect it direct from the restaurants deep fryers.
If I take it out it is app. 150 Celsius.
I use a commercial filtering machine.
> 5 microns.
I take it home and poor it into 200 liter plastic barrels.
It settles for 1 week before I filter it through 1 micron bag filter.
I do not see any water.
Having studied Mr. Schur’s findings and tests I decided to take the precaution long ago.
The Fachhochschule ( University ) Weihenstephan, Germany
who developed a standard for vegetable oil was one of my customers for HPLC equipment.
Their standard shows a water content of 0.075 % is not critical.
Whatever you make out of it…..I leave it to you.

"Bluoddie eck Nora"... I'm certainly no pioneer then; and cold climate seems not to be an impediment.

However it sounds like the oil is dry as he takes it out of the fryer hot himself so no little cleaning person has an opportunity to add water to it...

Well all that remains are the tests of how much water can be accomodated... it seems that if the water is not visible then the addition of the alcohol may be a viable alternative to heating...

The GP took its first hit today... Inspite of assuarnces from the supplier the CAV filter had zinc on the center post...

I looked in the fuel bowl this morning to see a large layer of milky supstance at the bottom. On closer investigation it was metal particles/goo and the post was heavily tarnished and discoloured.

I'm hoping it was just a coating and is not all zinc alloy, time will tell.

Fuel is still clear and unseparated.

bmwfan,
You have had no problems with wax from the diesel in your blends?
No flakes or slime in the filter or tank?

No.
I guess, our Canadian winterized Diesel prevents it.
Re : slime
I can’t comment on your experience with metal barrels and slime.
I use plastic barrels only.

Or possibly the Isopropyl alcohol in the mix keeps it from coming out of solution and precipitating out.

I do not know.
One thing for sure.
It works for me.
6 years and no defective injector pump.
Even more important the BMW uses rotary pumps.

BMW Fan do you have any problems with the blend thickening or gelling in winter and do you add heat to it in winter? ... single tank

I have not realized problems with gelling or thickening down to minus 10 Celsius.
If it is getting colder I add more Diesel and also gas.
Example:
60 / 30 / 5 / 5 WVO / Diesel / Gas / IPA
Schur adds also gas instead of Diesel.
The BMW 524 TD is equipped with a 110 Volt plug in ( rarely used ) and a plate heat exchanger.

Well the GP has now done 3,000 kms on the GP mix (being WVO;Kero:95%Ethanol 80:15:5) and luvs it, except for starting but it was hard to start on dino anyway and the new rings are not bedded yet...

I am now running the Nissan Turbo 2.8 motor on it (WVO;Kero:95%Ethanol 80:15:5)and it luvs it as well, no problems like I had on petrol/wvo: 20/80. Except now that its getting cold in the mornings after start and on idle it tends to miss badly... untill a bit of a run and a warm up.. obviously the stuff is too thick on a cold morning to inject properly until engine is warm

I need to add more kero... 25 - 30% I think will do it.
