This vehicle has a 5.9 litre Cummins Turbo Diesel engine with 6 inline cylinders and 24 valves. The fuel injection system is electronically contolled and built by Bosch. These pictures document some of the many stages of the modification process required to enable the engine to run on Canola Oil which I collect from various pubs and resteraunts after it has been used to fry food.. The truck does a little over 29 miles to the gallon on this waste product.
