Kits

Twin-tank vegetable oil systems have shown to be the most reliable method  of running diesel vehicles on vegetable oil. 

A diesel tank is used to run the vehicle until the engine is at operating temperature, the vehicle is then run on neat vegetable oil from the other tank until the end of the journey when the engine is flushed with diesel to prime it for the next cold start. Once installed, the vehicle is a diesel/vegoil hybrid, able to run happily on either vegetable oil or mineral diesel.

Since there are so many types of diesel engines on the road, there are many different 'levels' of kit that may be required to convert them to run on vegetable oil. Some vehicles may require no conversion at all (in the case of the early mercedes diesels) while others such as bosch equiped Puegeots may have a heated filter already and therefore will not require further heat at the filter. Typically, a good conversion kit should include a heated filter, a heat exchanger and a fuel select valve. Further components may be required for particular vehicles, for example an extra fuel pump or further temperature monitoring may be needed. 

The BioTuning Twin-Tank Kit is a standard kit of parts which includes all the components required for a good quality, efficient conversion kit as described above. It contains everything that is required to convert IDI and DI vehicles with Bosch VE and VP pumps or equivalent. It is not suitable for vehicles fitted with CAV pumps since it does not prevent switch over to veg before temperature is reached. Since it is a kit of standard parts, it would provide the core of any customised kit that you may want to develop, including one suitable for those CAV pumps if some extra precautions were made to eliminate the chance of cold vegoil in the pump. 

The SmartVeg kits have been designed to be complete vegoil conversion kits which are suitable for any diesel vehicle being based around a state-of-the-art electronic Control Module. There are as always the odd exceptions to these rules such as the HDIs which may require a fuel pump to be used in addition to the kit. The smartveg kits have been proven to safely work with CAV equiped vehicles thanks to the precautionary approach provided by the Control Module. We recommend adding a heated filter to these kits to ensure good efficient filtering particularly during winter.

For those on a budget but wanting to run on vegoil using the SmartVeg system, there is the option to build a system around the SmartVeg Control Module using a pair of solenoid valves, and a heat exchanger (and optionally a heated filter)....
