We at Greasecar are constantly trying to gather more information on technical specifics pertaining to using vegetable oil as a diesel fuel. There are many studies out there with varying statements and results. All statements made on this page 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 Greasecar 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.
