I ran two different vehicles on used vegetable oil / waste vegetable oil (WVO) for over 15 years, but have sold both of the vehicles and no longer need the remainig WVO. I have 50 gallons for sale that has been triple filtered down to one micron, cleaner than fuel you'd get at a filling station. You just need to bring your own container. I have a 350 gallon IBC tote that I'd be willing to sell as well.
