Thanks for the info. The more I look at this, carbon footprint reduction stuff, the more I think there is a huge opportunity for someone to cash in on the use of wvo by diesel drivers wanting to lower bills and footprint. I'm definitely going to try using it myself in the tdi90 and may look into it as a business....Plenty on previous threads about ev conversion and on German forum. It's not presently financially viable cf a second hand i3, e Golf, eup!, Leaf...
Also look up Elsbett WVO conversions - they invented PD system that VW bought.
Tell you MP and Council to support 10 million UK diesel drivers to lean on oil companies to supply #hvo made from waste not food for massive reduction in pollution and higher mpg #Helsinkibuses
I have put £20 of diesel in with 15 litres of veg oil (£3.50 for 5 litres at Tesco works out to 70p a litre) and have done almost 330 miles - am anticipating around 350 miles+ on the tank - not sure if this is good or bad for these engines but I have also got a JDD box (and no remap) on the car, and a big crack on the front bumper where the black part meets the coloured so would create some drag but I'm not sure how much. Also, the air filter hasn't been changed in the service as I found it in the boot!Hi Kaz, Have you tried the veg oil yet? the reading i've done suggests that the PD engine doesn't like running on veg due to the high pressure, and twin tanking and some other modifications are needed for it to work long term. Interested in hearing your experiences. cheers nod
