OK, but there is the hassle factor and the use of chemicals in the process and the need to have somewhere to put the processing equipment, not easy for some
[/QUOTE]Bio is a subsitute for diesel where as veg oil is an alternative fuel & requires modifications. You cannot run an engine on veg oil as the viscosity is lower & requires heat, it also plasticises & will coat the fuel system if not arranged properly, don't try it! [/QUOTE]
Agreed, most cars cannot just run on veggie oil, that's the point I was trying to make. But, many people do run cars like the Hilux Surf on a mix of diesel and SVO, varying the ratio depending on weather temperatures without problem. Personally I have never tried it and am not advising that anyone should, merely pointing out it can be done with some cars and careful consideration. I also mentioned the other option of preheating the oil - another conversion alternative.
I'm not saying any one way is the best and I ahve not tried any of the. But, Biggles was asking why more people are not doing it, I was merely trying to point out it's not that easy!
