I was wondering what the dangers were of using biodiesel that has failed the 3/27 ? if a diesel engine will run on svo anyway? I run b100 in my 03 F250 6.0

LOL.. that's about it...

I think it kind of depends what you are using the fuel for. The robustness of the engine in question is going to mean a lot

If you're running bio in your new volkswagon, I'd suggest you make sure its top quality fuel. If its to be used in a farm tractor or skidsteer, I would just go ahead an run it without worrying.

I don't own a 6.0, but from friends who do, I gather that they have an unusually sensitive fuel system.

If it were my 6.0, I'd only run very well converted fuel. Buy this I mean fuel which passes 3/27 with no cloudiness at 67f or lower.

BTW, at what temp. did your fuel fail 3/27 and by how much did it fail?

At 69 deg. Pretty clear, with very little fall out.

How long did it take until you saw the fallout?

carpenter,

I'd recommend re-processing. You should be able to pass 27/3 with very little in the way of additional ingredients, heat, and mixing.

Andrew's right- generally speaking, the newer the vehicle, the more sensitive to poor fuel.

What do you mean by sensitive I've used failed bio before and it all runs the same, great. I dont make a habit of using it. I was wondering if it had long term efects

Yes. And, I understand that that particular fuel system has issues bio or not. Then there is the issue of warranty and if the issue was caused by bio or just the fuel system failing.

Great question. Truth is, as far as I know, no one knows for sure. But, whatever issues might show up are more likely to show up with poor fuel than good fuel.

Personally, unless the conversion was pretty bad, I'd probably blend it with a later batch that is much more converted. I find it hard to imagine taking washed dried fuel and re-reacting it. But, it is your truck.

In the future, run 3/27 in process and don't stop until you pass.

3 min. at 69f tells me you are not real close to the pass/fail cusp. If you are on the cusp it will take more like 15-30 min to see the fallout, IME.

I am making 55 gal batches and if a batch fails I mix with batch before and after.I am making about 1 to 2 batches per week soon I hope to build a 500 gal prosser at that point I will be using only bio that passes

I have the same question. If it fails 27/3, is it still better than running SVO? Or are there other issues that could come of it?

Did the glycerine fail to drop out?When I made biodiesel with ethanol and 1-propanol, where the ethanol wasn't 199 proof the co solvent effect didn't allow the glycerine later to form. I washed the reaction product with distilled water to remove the glycerin and soap to obtain a product. What do you mean by a failed batch? There are no failures, we learn from them all. "The experiment was a total failure" , well its not.

When I say fail, I mean it didn't convert fully. I see some people on this site say not to use fuel that doesn't pass 27/3 but My thinking is that it is still better than SVO. Right?

The Glycerine seperated out. Then I water washed it, and dried it but it's not perfectly clear like biodiesel should be. I even took 2 lites out and heated it on the stove to make sure there was no water in it and it still didn't get clear.

The real problem with partially converted fuel is the intermediates that are in their like mono glycerides di glycerides & glycerine that will continue to separate. I dont think it is better than SVO you should use fully converted or SVO not stuff in between, unless of course it is a bunker oil burner you are running it in.
Also the intermediates are superior emulsifiers and hydrophyllic so moisture in your fuel will be a real problem if their is even a hint of soap near any of this and your in the poo. best of luck.

WatsonBrew; I expect mono and di glycerides have a high boiling point. Will they vaporize prior to ignition in a diesel engine,I don't know. If your 3/27 test failed fuel is dry, a drywash may remove the mono and di glycerides. Magnesol claimed that it did that years ago, when I think it was composed of magnesium silicate. The water wash removed most excess methanol, glycerine and soap. A drywash might remove the mono and di glycerides.

Ok, thanks for the info guys. Rather than risking any harm to my engine, I think I am going to put it in with my next batch to lower the titration of the oil. The oil I've been getting is pretty bad. It titrates around 9.
