"This page documents how I run waste vegetable oil (WVO) collected for free from restaurants dumpsters. They are glad to get it collected for free since they usually have to pay for removal in this area. The trick to doing this successfully without shortening your engine life is to run a 2 tank heated setup, and filter and dewater the WVO very well. And this is still an experiment where I won't know if the life was shortened for many years yet since these trucks are rated to last 350k miles before overhaul and this one has 140k after 12 years. Many people have driven >100k miles on VO already. I am an engineer, so I spent lots of time studying the conversion kits sold by many companies, and many online forums, and came up with my own design which I think is more reliable, simpler, and cost far less.This truck from 94-98.5 is one of the best diesel engines to convert to VO since its got a strong mechanical fuel injection pump. It burns cleaner than diesel and the exhaust smells like a BBQ grill."

After a year of design and testing I'm proud to say that my filtering system works great. The whole project cost about $300 and removes all water and particles down to 5 micron. The process starts with pouring the used oil into a five gallon bucket mounted over a 30 gallon transparent drum. The oil flows through a straining bag into the drum and permitted to settle. The water is allowed to accumilate at the bottom and can be drained from the bottom tap. The product is then pumped from the primary drum eight inches above the drain to avoid the contaminated oil. The oil then passes through a 30 micron Stanadyne FM100 filter, the Filrite pump and then another Stanadyne FM100 5 micron filter to the secondary holding drum or the car tank. This method has worked, without fail for almost a year before changing the FM100 filters. The screening bag filter is easy to clean in the washing machine about every month and allowed to dry.
