With all the natural resources that are extensively being used for our own purpose has resulted in identifying and using an alternate form of energy and resource in order to retain at least the existing natural resource. It is high time to move towards other energy resources before a situation of all the natural resources being exhausted. In vehicle fuel the alternative form that could be used as fuel is the vegetable oil and even waste vegetable oil wvo. This vegetable oil has to be converted to such a way that it could be used as a fuel in any of the diesel engines that is using either diesel or petrol as their fuel so long.The wvo conversion to an edible fuel involves a lot of procedures and process so that wvo could be used as a fuel to engines and in all other possible machines. There are so many ways through which wvo conversion to a fuel could be achieved and the most popular conversion technique is to centrifugal force to split the contents of the vegetable oil and then we could use that as fuel to the diesel and in any other engines, as an alternate to petrol and diesel.
