I've got the Greasecar system in Milwaukee. I've yet to get a good source, and the cold weather seems to be a bad time to raid grease dumpsters. The system has worked, though it can take 3/4 of my drive to work to heat up to 80C. I've been testing it out once in a while on store-bought oil, and it seems to work fine, but I know other systems use electric heaters to make sure it's hot enough. I'm getting a few drums this week to set up Dana's prefiltering, and I'll probably add more insulation on the fuel lines.
