WVO stands for Waste Vegetable Oil. It can be used in place of diesel fuel with some modifications to the vehicle.  Generally, WVO needs to be heated before it can be used as a fuel.  Modifications to your car usually include an additional tank for the WVO or some way to preheat the oil before it reaches the engine.  Additionally, the oil must be filtered before you put it in your tank.  Most WVO users feel that the best level of filtration is down to 5 microns or better.

Vegetable Oil as Substitute for Diesel by Glady Reign

The current global warming issue has sparked great interest in the development of newer and cleaner sources of energy aside from fossil fuel. Fossil fuels are non-renewable and when fuels from this resource are burned, they produce harmful gases which trap heat in the atmosphere thus the greenhouse effect.

WVO (Waste Vegetable Oil) or SVO (Straight Vegetable Oil) can be used as fuel for vehicles that use a diesel engine. WVO is that oil that has been recycled and filtered using generally cooked oil from restaurant fryers and SVO is considered pure, uncooked and fresh vegetable oil.  It is also possible to make your own biodiesel from vegetable oil.

Originally, the first diesel engines were designed to run on peanut oil, so it makes sense that a modern diesel engine could use vegetable oil.  In fact, most diesel engines can run without any modifications by pouring vegetable oil straight into the tank.  However, without some modifications there are a host of problems that can occur doing this including poor atomisation of the fuel, incomplete combustion, coking in the injectors, ring carbonisation, and accumulation of fuel in the lubricating oil. These things will lead to poor performance in the best case and possible engine failure in some situations.
