bio-d problem
A friend was told yesturday that he couldn't get bio-d because the temperture was too cold. They told him that the fuel was seperating in their tanks and couldn't get it to flow right. He has a crane and framing business, supply was Cystal Flash. Has anyone else heard of this? Located in SW Michigan. Lee

we been having problems with our school bus fleet. But pretty sure it not actually the bio diesel, but the quality control of the mixer/man. We been having filter clogged up. So we started cutting them open, and found a thick goo plugging the elements.
Here is the important part.
It looks very much like animal fat, yellowish crisco if you remember crisco.
that should not be in bio diesel, only vegtable oil, which if you set some outside you will see must get very very very cold to gel.
Animal products however solidify very easily, just drain some bacon fat and stick it in the fridge.
what we are getting looks just like that, so , it is not boi[diesel, it is whatever crap they slipped in there in place of the vegtable oil that is giving us problems.

yes because it started when it first stated to get cold, and i mean ky, so its not the great white north. When you look at you can tell it is not part of the mix. I the filters get warm, and the diesel should return to normal.
We checked one in the am when it wouldnt start, it was just around freezing. Too the filter off, dumped it fine no restrictions. Cut it open, and the element was covered in goo. Which peeled right off, and we left it in the diesel, and it always stayed togther like a big goober.

I've read where some B100 will gell in the low 40's. You didn't say what mix of Bio you are running, but were both mixes the same? There are also additives that can be put in to change the gel point of Bio. Perhaps the old supplier was adding an additive and the new supplier is not.

FOUND THE PROBLEM. Seems the supplier had invested in the local bio plant and it went belly up for some reason, so supplier had to have his trucked in, trucking was getting to expensive so they desided to cancel bio until next spring. Hope this didn't scare anybody too much, did find it interesting to see that some of you are actually having a slight problem. Lee

Bio D does have a lower gel point than striaght #2 diesel, that is part of the reason why most places switch to a lower concentration of bio during the winter or get rid of the bio altogether and run a straight mix of #1 and #2.
