Been reading about biodiesel from Waste Vegetable Oil (fast food joints). There was another seminar at the farm show where I was speaking on bees. You Tube has a bunch of guys making kitchen-grade blender batches.
I've read the archived searches on biodiesel.
Apart from the opinions and P&R, has anyone on this list actually a) converted their diesel to run on straight WVO, or b) bought one of those fuel meister units (around $3 grand) to transform WVO with methanol and lye?
