Waste Vegetable Oil (WVO): Headache or "The Answer"

I've been running two waste vegetable oil greasecars for a while now, and even though the WVO cleans the injectors and produces less toxic pollutants and greenhouse gases, THE SYSTEM TAKES MAINTENANCE.

Anyone who tries to sell you a WVO or SVO conversion kit that says that all you have to do is install it and then drive for free for the rest of your life is a liar.

Right now I have a dead vegetable oil level guage, two coolant lines that have worn because they've been rubbing against the frame, and they need to be pulled and re-routed, and i just lost my source of waste vegetable oil (the restaurant owner wants to use it for himself).

Now, I have found new source of oil that is really great stuff, but I still need to set up some way to get the water out of it since the cooks clean the fryer with water. (Water + WVO = dead Injection Pump = $1,000-$2,000 repair).

So sure, WVO is a great way to help move the world to a less-fossil fuel dependent state, and sure it helps reduce our contributions to global warming, but don't be blind: it takes maintenance and work. At times I can completely understand people who just want to roll up to a gas station and say "fill 'er up."
