Motor oil made from oilseed rape (canola) will be available in the US in
around six months.
Fuel from oilseed rape has been in use for several years. Last week, a
company in Michigan that makes cooking oil joined forces with another that
specialises in agricultural research in Colorado to mass-produce and sell
lubricating oil from rapeseed in Michigan. The companies say replacing
petroleum-based motor oils with the new oil cuts friction by half, so engines
can run at lower temperatures and will wear more slowly.
