Converting your diesel engine to burn Used Fryer Oil (UFO Fuel™) reduces operating expenses, reduces exhaust emissions, and reduces our dependence on foreign oil and associated negative environmental impacts. (Left - Chevy CHUB converted to burn Used fryer oil as fuel.)

First, the exhaust from a gasoline engine is different from the exhaust from a diesel engine. Diesel engines produce primarily nitrogen oxides, with a small amount of soot and a small amount of organic compounds with relatively low volatility; these organic compounds can be, however, fairly harmful. Gasoline engines produce primarily carbon monoxide, nitrogen oxides, a wide mix of organic compounds, and some small particles, all in the amounts that are much higher than in diesel exhaust.

USED FRYER OIL AS FUEL TECHNICAL DATA

All statements made below pertain specifically to vehicles modified using the Greasecar© Vegetable Fuel System.
All studies with ASTM specifications are conducted by certified independent laboratories. Emissions testing is being conducted with assistance from Michal Vojtisek-Lom.

EMISSIONS TESTING

Report is given here on diesel, biodiesel and Used Fryer Oil comparison on a 1981 VW Vanagon by P. Joshua Wilson and Michal Vojtisek-Lom.

• HC, CO, CO2, NO measured by dual repair-grade five-gas analyzers
• PM measured by light scattering
• Exhaust flow determined computationally
• Monitoring system was installed in the vehicle and operated while vehicle was driven on the road
• Vehicle tested on a rural highway from Superior interstate highway exit to a four-way stop sign, and back.
