Mercedes 300SD. Purchased for $850 and converted to run on waste veggie oil. This project was innovative in that the dirty oil was run through a strainer and then pumped through a multi-pass centrifuge originally designed to clean motor oil in tractor-trailers.
Traditionally, waste veggie oil is filtered through a membrane or "sock" filter, however this creates waste and the need to constantly purchase new filter membranes. The use of a centrifuge eliminates this recurring cost, is faster to use, and gets the oil much cleaner than a sock filter. Plus, the unique construction of the centrifuge allows any water in the oil to flash evaporate.
This device was able to remove impurities from used cooking oil, allowing it to be run in the engine just like diesel. Most photos show the trunk where the dirty oil tank resides, and the clean oil tank is underneath where the spare tire used to be. This was built as a proof-of-concept.
The stock diesel tank remains intact and there is a 3-way toggle switch to change fuel tanks.
