"Please stop and think before you post. If you would have at least made some attempt to understand the application I could give you a shred of credibility."
You completely missed the point of my post.
I have many times stated that people should use 20% SVO over 20% biodiesel due to the fact that SVO is much more available, and it works, two points I think I made in this thread.
While doing more research and building a processor, the OP could simply pour in 20% SVO and be off to a good start w/o any effort or inconveniance. This might meet all their goals. Once they were satisfied 20% SVO worked, they could switch to well filtered WVO to save money.
And 20% SVO will not gell or settle just because you say it will. Physics is on my side. Check the Schur fuel charts.

If you have no knowledge of Schur, you do not have any knowledge of running unheated veggie / diesel blends.
"TECHNICAL INFORMATION
Attempts and results
About 100 different Diesel units are operated at present with SCHUR ECOFUEL. Of 1,6 litres of Diesel cars up to LKWs (VOLVO F 12) an extensive spectrum is tested. At the engines no changes were made.
At the university high home, Stuttgart, Germany, was driven an engine permanent run of over 650 hours on the test stand (fig.1). The engine was examined by the engine manufacturer (MWM Mannheim). The result was addressing according to statements of the responsible persons.
A Mercedes Benz of 300 turbo-Diesels is operated without problems since more than 200,000 km with the fuel. The engine of this vehicle was so far three times partly divided and by the companies. Hoeckle, Moessingen, examined (see reports). The results were very positive. Were neither nonspecific carbon deposits to recognize nor gluings of the piston rings or other damage. Surprising way was cleaner the inside of the engine with each examination of the engine than during the preceding dismantling, which suggests that the fuel has also a cleaning effect. The emission values of the vehicle were measured twice with the TUEV and found good.
A tractor (DEUTZ), which for more than 1800 hours with SCHUR ECOFUEL is operated, perfectly one divided and one examined after a run achievement from approximately 1200 hours. The obtained results were again very positive. According to enclosed report no significant damage was visible and all experts was very content with the results.
A tractor (Holder), which for more than 1400 hours with SCHUR ECOFUEL is operated, after a run achievement from approximately 700 hours, by a mechanic of the engine manufacturer (KHD), completely one divided. The results corresponded more near above to the described.
So far with the SCHUR ECOFUEL a complete run achievement was reached of more as 1.000.000 km in pre-chamber diesel engines and more than 8000 hours in directly injecting diesel engines.
Experiences and recommendations
Past experiences showed that in dependence of the purity of the used vegetable oil, a verkuerzung of the changing interval for fuel filters becomes necessary.
In order to prevent the negative consequences of schmieroelverduennungen, we recommend a halving of the oil change interval with directinjecting diesel engines.
Directinjecting diesel engines are not applicable when main use in the Niederlastbereich (under 30 % load during longer periods) without Diesel fuel admixture (at least 50 %).

All data were determined. Many merging were examined not for cooling stability, there the requirement to the RWS Diesel on a flash point entspr. Diesel fuel, as well as energy content of the mixture and practical tests lay.

Why not try reading some of the posted research instead of castigating me about a subject you obviously know nothing about????
Why not send me that video of veggie settling in a jar?
There are hundreds of SVO fuel stations in Germany. I have no doubt , that as I write this, someone in Germany is fueling with SVO and diesel in a splash blend. If what BKMetz asserts is true, hundreds of German SVO'ers would be lining the curbs by now with gelled or separated fuel tanks. This is definately not the case.
I've challenged you to prove a blend will settle.
I've challenged you to prove a minor blend will coke an engine.
I'm waiting for something more than '..I don't what else to say..'
"The veggie oil tends not mix well and settle in a layer."
Ok. Show an example. Or a report. have you ever tried blending SVO+dzl in jars yourself?
I have.
- In jars, with WVO of various filtrations. It blends readily.
[Actually, it would be a challenge to keep them separated.]
Here's my report at infopop:
"I am very interested in this problem too, as I use an 80/20 wvo/(gas or diesel or kerosene) blend in my two vehicles. I have always just added the two components separately, 3 - 6 gallons at a time. I haven't had any noticeble problem.
But I decided to test some blends in a clear glass jar.
Test #1
1/3 bottle of settle filtered canola wvo and
1/6 bottle of gasoline.
WVO first, gas dribled in as slow as possible to simulate tank filling. Both fuels were at 45*F.
Result: Gas formed a layer on top of the wvo and did not mix for 2 minutes.
Test #2
Same jar as #1, gently jiggled the jar to simulate tank sloshing. Only 1/2" jiggles, no inversions or shaking.
Result: gasoline layer shrank a little, some mixing occurred.
Test #3
Added 1/6 biodiesel, hoping it might promote mixing.
Result:
The gasoline layer got bigger, but not the wvo layer.
Test #4
Covered the jar and shook it for 10 seconds.
Completely mixed. No settleing after 2 min.'s
Test #5
First gasoline, then wvo. Again dribbled in.
The gasoline floated to the surface and formed a layer as in test #1, ON TOP OF the WVO!
Test #6
A new jar of 1/3 biodiesel and 1/3 gasoline dribbled in. Mixed readily w/o jiggleing or shaking. Same with bd added to gasoline.
Conclusions:
Gasoline and biodiesel mix readily w/o mixing.
Gasoline and wvo don't blend w/o mixing.
From now on, I'll have to add the gasoline/kerosene/diesel to the wvo and shake it in a 5 gallon jug."
Note: After making this post I discovered that the level of filtration effected the blending.
The WVO used in the test above was only filtered to 100 micron.
WVO filtered to 1 micron had no problems mixing and could not form a layer as seen in the first tests.
Thats why I specified SVO in the fuel mixing challenge, to ensure it met fuel standards.
- In my car for 72,000 miles w/ only one gelling incident at 18*F. [B80 would have jelled too.]
More on Schur:
Schur-Mischung
Die Schur-Mischung (oder Schurmischung) ist nach H. Schur benannt, der etwa ab 1993 ein Verfahren suchte, reines Pflanzenöl ( Pöl ) durch Zumischung anderer Stoffe in relativ geringem Anteil in herkömmlichen (nicht modifizierten) Dieselmotoren verfahren zu können. The Schur-Mischung (or Schurmischung) is named after H. Schur, at about 1993 a procedure sought, pure vegetable oil (Pöl) Zumischung other substances in a relatively small share in conventional (unmodified) diesel engines to be able to proceed. Reines Pöl hat eine wesentlich höhere Viskosität, als herkömmlicher Dieselkraftstoff. Pure Pöl has a much higher viscosity than conventional diesel fuel. Ferner liegt der Flammpunkt deutlich höher, was bei kalter Witterung und kaltem Motor Startprobleme verursacht. Moreover, the flash point significantly higher, which in cold weather and cold engine startup problems.
Der im Oktober 2000 veröffentlichte Bericht beschreibt die Ergebnisse seiner Experimente mit "SCHUR-ECOFUEL", wie er sein Diesel-Kraftstoff-Substitut nannte. The October 2000 published report describes the results of his experiments with "SCHUR-ECOFUEL", as he Diesel-Kraftstoff-Substitut called.
Einige Pflanzenölfahrer mit Direkteinspritzer-Dieseln nutzen heute solche Mischungen, um ihren modernen Motor trotz der Probleme mit 100% Pflanzenöl im 1-Tank Prinzip oder gar ohne Umbauten zu betreiben. Some drivers vegetable oil with Direkteinspritzer-Dieseln use today such mixtures to its modern engine despite the problems with 100% vegetable oil in 1-Tank principle, or even to operate without modifications.
Herstellung, Komponenten Manufacturing, components
Den größten Teil der Schurmischung bildet mit etwa 80% natürlich das Pflanzenöl. The largest part of the Schurmischung formed with about 80% of course, the vegetable oil. Die zwei weiteren Komponenten Benzin und IPA füllen die übrigen 20% zu etwa gleichen Teilen. The two other components of gasoline and IPA fill the remaining 20% to roughly equal parts. Das Mischungsverhältnis kann je nach Witterung und individuellen Erfahrungen mit dem eigenen Motor angepasst werden um eines der Grundprinzipien (s.u.) zu verstärken. The mixing ratio can vary according to weather and individual experiences with its own engine to be one of the basic principles (see below).
Prinzip Principle
Zwei Komponenten, zwei Ziele: Das Benzin hat sich als geeigneter Zusatz erwiesen, um das Pflanzenöl dünnflüssiger zu machen. Two-component, two objectives: The fuel has to be appropriate additional proved to vegetable oil to make thinner. Schon 10% Benzin im Pöl bringen einen erheblichen Unterschied. Already 10% Fueled by Pöl bring a significant difference. Dadurch kann der Kraftstoff bei der Einspritzung in den Brennraum feiner zerstäubt werden und zündet entsprechend besser. This allows the fuel injection in the combustion chamber in the fine sputters and better lighting accordingly. Ein weiterer Effekt ist eine sog. Kaskadenzündung. Another effect is a so-called cascade ignition. Auch wenn Benzin ein schlechter Selbstzünder ist, unterstützt der flüchtige Brennstoff nach der Zündung des Gemisches die Verbrennung. Even though gasoline is a bad ignition engines, fuel, the volatile after the ignition of the mixture combustion.
Die weitere Komponente Isopropylalkohol ist dagegen im Vergleich zum Benzin ein idealer Selbstzünder mit einem Flammpunkt von 12°C und bewirkt eine Zündung des Gemischs bei geringerer Kompressionstemperatur als mit reinem Pflanzenöl (Flammpunkt ca. 300°C). The other component of isopropyl alcohol on the other hand is compared to an ideal fuel ignition engines with a flash point of 12 ° C and causes an ignition of the mixture at a lower temperature than compression with pure vegetable oil (flashpoint approximately 300 ° C).
Im Zusammenspiel ergeben diese Faktoren ein Kraftstoffgemisch, dass ohne aufwändige Veresterungsprozesse wie bei Biodiesel den Eigenschaften von fossilem Diesel relativ nah kommt. The interplay of these factors
result in a fuel mixture that without costly Veresterungsprozesse like biodiesel the properties of fossil diesel
relatively close.
