Canola oil-powered 4WD

Canola oil-powered 4WD

Paul Henson, shown here in 2006 filling his 4WD vehicle, had driven 12,000 kilometres using canola oil and just a touch of diesel. A $1000 conversion kit and waste oil from a local restaurant got him fuel for 50 cents a litre that was far less polluting than fossil diesel or petrol. Commercially produced biodiesel can be made from milk, tallow or plants like canola. New Zealand-grown canola biodiesel produces 42% less greenhouse gas than that of fossil diesel. The energy content is similar: 1.08 kilograms of canola biodiesel has the same energy content as 1 kilogram of fossil diesel.
