• You have to add other chemicals too, it%26#039;s not as simple as that and it%26#039;s not tax free either. Work for a company that makes bio-diesel
• I heard it works, but wouldn%26#039;t peanut oil smell better?
• I can%26#039;t even understand the ?
• I%26#039;m pretty sure the inventor of the diesel engine designed it to run on vegetable oils in the first place, so aside from seal degradation I don%26#039;t see what the problem would be.
• you have to do other things to the vegetable oil before you mix it. there is some chemical in it that you have to remove using some type of filtration. I don%26#039;t doubt that it would run on 60/40 at all but it could do some damage, and gum up your stuff.
• top gear did this experiment a couple of years ago and it works best with used veg oil and all you need to do is for every 97ml of oil you add 3 ml of non kerosene based white spirit and it was about 26p a litre if you decide to tell the taxman
• There are many blogs giving all details on this. Of course there is the tax issue as any fuel used in theory should be fuel tax paid but put that aside and you get:
  
  Modern diesels, especially common rail do not like straight veg oil (SVO). Also some diesels do not like biodiesel because it can damaged some seals in the fuel system. Some people even fit two fuel tanks to start up on ordinary diesel then switch over to SVO when engine is warm and then keep SVO tank heated to avoid waxing. Even fossil diesel can wax if you have summer diesel in a cold place. They actually sell different fossil diesel in places like Scotland and Scandinavia to reduce waxing but that is also one reason why diesel is less popular in cold climates. To avoid dual tanks and fuel systems some people report no probs with older diesels on mixes of SVO and fossil diesel but of course warranty goes out the window (is this an issue with a 1992 Shogun?) and you can get some gumming up. SVO is not biodiesel which is chemically transformed from SVO but it is one alternative. Other answers are right in that in times past people ran all sorts of diesel engines on all sorts of fuels.
  
  I recommend googling SVO for more info before you jump in and risk damaging your motor. Some fuel systems cope with SVO, some dont.
• The guys on the Myth Busters show, ran a Volvo on pure veg oil with no modifications. I don%26#039;t see why a mixture of both veg oil and diesel wouldn%26#039;t work.
