Waste Vegetable Oil Fuels

This must not have been a very tenacious emulsion. I’ve had worse. After about an hour of heating (we have a heating element installed in our wash tank) and misting with heated water there has been some serious progress. It looks to me that I’m about half way done. Maybe by tonight I’ll be back […]

How many times have I been warned and have I gone against these warnings? Add one more! The third batch is in the wash tank. It looked very nice coming out of the processor. There was no obvious separation between the glycerin and the biodiesel so I erred on getting more biodiesel and included […]

So I’m still working on my second batch. Yeah, I know I’ve been doing that for quite some time now, but I’ve been out of town for work, on the river and not had a diesel (in the shop), so I figure that those are good excuses.
