Please read this long post-

I recently put a 100 gal "L" shaped auxillary tank in my bed. It was used to hold WVO before I got it. It was never cleaned to brand new inside- I drove around with about 3" of soapy water in it, drained and flushed it, then for the past I two weeks I drove around with about 5 gals of #2 in it to loosen up any crud (old wvo). This friday, I put 30 gallons of b100 in it for the first time. I welded a bung into the side with a 1/2" ball valve that ties into the main tank vent line, so that way there's no fuel lines coming out the top of the tank. Well, today I was putting #2 in the main tank, and I noticed that the air escaping from my main tank was HARSH- it smelled like a strong turpentine, it smelled very volatile, unlike either diesel or bio, which both don't have much of a smell to them. Is this smell from the old wvo fermenting or something?? Any one know if this smell is indicative of something bad that may happen? Oh, BTW, already replaced the first fuel filter- putting on the Vormax tomorrow to cathc the rest of the aux tank crud. Thanks everyone!

 

When WVO is exposed to air it turns rancid, and STINKS! just flush out with B-100 and all should be fine.

 

Roger that fabman- I'm just concerned at the eyewatering ability of these fumes- I've smelled what I believed to be rancid wvo before (PEEEYOU!!) but this stuff is more along the lines of a good solvent type smell. Oh well, payday is around the corner, so I can fill the whole 105 gal tank and purge the smell!

 

Update- I found out the strong smell is the methanol- my bio guy doesn't reclaim it.

 

Not good, Raw biodiesel is not very good for your truck..........

 

What do you mean not good- I have about 140 gallons of this stuff!! What should I do? It seems to be running fine...

 

Use it up! Short time use has a low probability of engine damage.

I would not get anymore bio from your "friend", at least untill his quality improves....

Its stuff like this that really makes me boil I would never sell or give away raw biodiesel, nor would I use it myself. It's just not worth the risk. Every study I've read [ and I've read a lot!] shows that using raw, unwashed, biodiesel will KILL an engine over time...........When, who knows, but it will cause damage!

I'm probably **** about quality........I've spent the last 4 years perfecting my process, but I know that the biodiesel I make is the best quality I can produce.
