The best oil for the wok is rice oil (because of its high smoke point, 490Â°F, 254Â°C). Peanut oil is not bad either and more commonly used. It is not healthy to heat any oil too far, so it's best to add the oil very shortly before adding products to the wok so the products can cool the oil during the stir frying.
Vegetable oil can be used as an alternative fuel in diesel engines and in heating oil burners.When vegetable oil is used directly as a fuel, in either modified or unmodified equipment, it is referred to as straight vegetable oil (SVO) or pure plant oil (PPO).onventional diesel engines can be modified to help ensure that the viscosity of the vegetable oil is low enough to allow proper atomization of the fuel. This prevents incomplete combustion, which would damage the engine by causing a build-up of carbon.
