 Vegetable oil is a biofuel, and as such is virtually carbon-neutral. This means that the carbon dioxide (CO2) released when the fuel is burnt is absorbed by the plants that will provide the next crop of oil (although we only support the use of cleaned, waste cooking oil - see below). Vegetable oil is a biofuel, and as such is virtually carbon-neutral.

 As the world moves towards electric vehicles, this topic becomes less relevant. However, we don't know what's around the corner, and diesel engines may be required for agriculture and distribution in case of breakdown of essential supply chains for whatever reason. As the world moves towards electric vehicles, this topic becomes less relevant.

 An extra tank is added for veg oil. You start with diesel, then switch to veg oil when the engine is hot, and it's continually heated via a heat exchange system. Before stopping, switch to the diesel tank again so that there will be mineral diesel in the fuel line when you come to start your car again. Cost installed c. £800.

-### Simple one-tank method+==== Simple one-tank method ====
  
 It’s simpler – you don’t have to remember to switch to mineral diesel near the end of your journey, and veg oil and mineral diesel can be mixed in the same tank. A simple one-tank conversion involves pre-heating the oil before it gets to the cylinders, and is only possible with indirect injection vehicles (D, TD, not DI, TDI, HDI, SDI etc.), because they have a separate chamber for atomising the fuel before it reaches the pistons, so cold starting on veg oil is fine. Also, a new, wider fuel line is installed between the fuel tank and the heat exchanger, because of the extra viscosity of vegetable oil.

 [[http://www.elsbett.com|Elsbett]] is a German kit with a few installers in the UK. They've designed an engine where veg oil is the fuel and the coolant, so it gets continually heated. When starting from cold, there's an electrically-heated jacket on the fuel filter. However, they advise against using waste oil. [[http://www.elsbett.com|Elsbett]] is a German kit with a few installers in the UK.
