We bought Darla the Dodge back in June with the goal of running her on waste vegetable oil. We found a great mechanic who was able to do the conversion in about two weeks. Nico works and lives all the way out in Ventura, but has been fantastic in answering all of our mechanically challenged questions. Nico installed a second tank in the bed of the trunk
so we can use switch our fuel back and forth between pure waste veggie oil and diesel or bio-diesel.
I don't have time to chronicle all the ups and downs we've had with Darla since then, but at some point I will.
