Hi glort, yes I have a little expereance with veggie. I have a 81 300sd I run on veggie,I also run a listeroid on on veggie. My plan with the new rv is to use one of the lower storage units and install two veggie tanks one will be for filtered the other for oil just picked up. Have a filter system that circulates the oil several times. What do you know about centrifuges? Pressurized ie dieselcraft or the bigger units, dose it take out some of the glycerin and thin the oil at all?
So far I have been heating the oil with a old gas frier then filtering.
