We are a family of four embarking on a nomadic cross-country trip in a school bus we're converting into an RV that runs on WVO. We're hoping to be able to find oil along the road, if you have any or know of a good source, to share or sell, we'd love to hear about it. We're traveling from New England to the Pacific Northwest starting in September '08. We'll be hitting CT, MA, NY, PA, OH, MI, WI, IL and TN to start off. We'll have the capacity to filter on the road, so decent quality dumpster grade would be fine. You can reach me directly at radicalarts@ecoisp.com. Thanks! Chris

Hey there!
I am about to do the same thing - but from the opposite side! I wish I had some suggestions, but right now I am focusing on trying to create a portable filtration system.
If I get any bright ideas, I'll be sure to inform you! Good luck on your trip!

Drop me a line if you make it to Vancouver Island, BC, Canada. We should have some oil to spare.
