Re: While this is well and good, Bacon topics should not be in here...
It should be noted that I have no Bio-diesel / Veggie Oil expertise, but as we all know, it has never been a requirement in Lemons to know what you are doing.
So start with a deep fryer filled with Peanut oil, which I heard is the best to run in old Benz's. Fry up a shit load of Bacon, which you use to bribe the Judges & feed any & all bacon lovers at the track. Let it cool & settle, Filter it out & run it in your car with an inline fuel heater like my cousin has on his old Veggie-Oil Benz. For Good measure... Paint it up as a slab of Bacon.....Win,Win Win!
I happen to know that you can get 10lb boxes of bacon EXTREMELY inexpensively at Costco. It ain't good bacon, but it's bacon.
But perhaps even better, the grocery stores around here stock a brand that comes in a white-and-orange cardboard package (I'll look at the name next time I'm passing the fridge). It's total crap but it's often like $1.50/lb and even more importantly for this project, many of the packages are almost entirely fat.
