Bio diesel production and / or diesel conversion to waste veg oil useage. Frontera 2.3 td vehicle?
Answers:
Pro: Used vegetable oil is CHEAP (try free).
Con: It contains Glycerine, which can CLOG the engine.
Both are true. There are 2 ways around this. Have 2 tanks in your vehicle, with a valve that lets you select a tank. One tank contains commercial #2 diesel. The other contains the used oil (after it has settled for 1 to 2 months). Start the engine on the commercial tank. When the engine reaches operating temperature, switch to the used oil tank. At operating temperature, the engine can handle the glycerine.
The other method is to "convert" the used oil. I have no idea what that entails. I only know that it costs from $200 and up. Converted oil eliminates the need to have commercial fuel for warm up. Google "biodiesel" and I'm sure you will find a site that describes the conversion process.

Biodiesel is totally legal in the UK as long as the tax has been paid on it. If you do get pulled which is unlikely as tests on vehicle fuel only normally occur on large commercial vehicles like trucks, if you have paperwork to show you make your own and pay tax on it there will not be a problem.
As for methods of making the stuff, the internet is full of useful websites to show you how it can be done. The method is called 'transesterification', whereby chemicals are added to new or used vegetable oil stock to remove the fatty acids etc from it so it can be used in your engine. We are in the process of writing some articles on the subject but in the meantime, here are some really useful links ;
