- - Anyone out there make their own biodiesel? (http://forums.pelicanparts.com/off-topic-discussions/306015-anyone-out-there-make-their-own-biodiesel.html)

Many people on TDIClub are argueing that the increased viscosity of SVO/WVO over D#2 is enough to cause excessive wear/damage to the cold start regulator in the injection pump. That and nozzle plugging are the only 2 downsides I see to a SVO/WVO conversion. That said, do you run a 2 tank system?
Just recently there was a thread on there about a fellow who had a nozzle plug, spraying the oil straight on the piston crown and into the chamber in the piston. It melted a hole right through it and he suffered a catastrophic engine failure including an engine runaway from the excessive crankcase pressure. Sounds like it would have been lots of fun to watch!

Anybody running WVO/SVO in a TDI PD is just plain stupid. I don't even want to get into that. Warranty issues aside, it's still stupid :)

If I were to run SVO/WVO I would go get an older diesel, perhaps one of the older mercedes diesels. Those things are pretty much bulletproof.

I just found a local biodiesel supplier who is selling for ~$0.75/L, so I don't think I'm going to brew my own any time soon. I was only spending $160/month on fuel in the first place. I'll probably run B10 all the way up to maybe B50 or B75. Depends on my mood and the weather. I just made contact with the guy, hopefully he can come through with a big drum of it for me :D

From my friend making Biodiesel:

Most homebrew biodiesel is "not". To do it right and certify it you simply must have the lab equipment to test it throughout the process and at the end it must meet the spec's for ASTM 6751. If it does, then it's biodiesel. If it does not then it's something else and preformance will reflect accordingly.

The good news is that diesels are built strong and will run on anything that will atomize and combust under 18 to 1 compression. The bad news is that eventually even the strong grow damaged with enough abuse, so if the fuel is not preforming "well" the components have to take up the slack.

I've been watching this thread for awhile now:
