Hi All, There seems to be a lot of confusion re,Bio fuel etc, I will try my best to give what limited knowlage I have on this hoping that together we can gain more of same. A few glosaries used and missused- WVO- Waste vegiteble oil as it comes from the resteraunt. SVO-Streight vegie oil,as it comes from the supermarket. Bio-When its been prosessed and cleaned up. Black diesel- Sump oil that has been filtered and mixed with diesel. Dino-Diesel that you buy and pay through the nose for at the garage.- Called Dino becouse its short for dinosor. For some time the UK government has allowed the use of Bio in quantitys of 2500lts per year for your own consuption. Most older diesel motors will run on Bio or a mixture of Bio & Dino without any modification. If you want to run WVO or SVO you may need to modifiy slightly,mainly to get the viscosity down to a figure your injector pump will take. There are very good websites for this type of thing, one being Diesel Bob. Any one with any info will be appreciated. Any one with stupid remarks re bad grammer,spelling,will be agnored. Regards, Dave.
