Trying to compare Biodiesel, Veg Oil and LPG is a pointless exercise in truth. Obviously both Biodiesel and Vegetable Oil can run in diesel engines, whilst LPG only runs in Petrol engines.
However, there were certain factors that I wanted to compare between fuel types when I first looked at veg oil conversion, and these are fiscal and environmental. I can't claim the following is scientifically backed with impeachable data as it's made up but myself from snippets of information I was able to glean from the internet - a not always reliable source.
So with that said, take what you will from the below:
LPG | BIODIESEL | VEG OIL | |
---|---|---|---|
Fuel Cost | Least expensive | Slightly cheaper than standard diesel | Cheaper than Biodiesel |
Sustainable | No | Yes | Yes |
Fossil Fuel Content | Most of it | A small part | None |
Emissions | 20% of standard petrol | Some, but better than LPG | Few, the best of the bunch |
