Coconut oil has been tested for use as a feedstock for biodiesel to use as a diesel engine fuel. In this manner, it can be applied to power generators and transport using diesel engines. Since straight coconut oil has a high gelling temperature (22–25 °C), a high viscosity, and a minimum combustion chamber temperature of (to avoid polymerization of the fuel), coconut oil typically is transesterified to make biodiesel. Use of B100 (100% biodiesel) is possible only in temperate climates, as the gel point is approximately . The oil must meet the Weihenstephan standard to use pure vegetable oil as a fuel. Moderate to severe damage from carbonisation and clogging would occur in an unmodified engine.
