Biodiesel and SVO in a 90TD
Leslie Henson:
Don't think there is such a thing as 'best'. You will smell the difference in the exhaust fumes though, so if you filter a drum of used oil from the local kebab shop, expect a queue of drunks to be stood at the side of your truck late at night. I put 3-litres of sunflower oil in 1/4 tank of diesel on a s3 to get it through the emissions that it had previously failed on. It then passed, but you could smell the difference in the exhaust fumes.

Rapeseed
Be careful with chip shop/restaurant oil.... as most now use soya based oil and not sure how this will react in the engine :shock:
If someone out there can verify whether soya oil can be used... id appreciate it. Cheers :D
AbyssDJ:
been running our 200tdi anywhere between 25-50% veg oil... had no problems so far, made it quieter, AND cleaned it out and made it run better!

Rapeseed oil is best thinner.
However IMHO Bio Diesel is best . I have read bad things about Veg Derv mixing on the engine. If you want to go down the veg oil route then a proper conversion is the best option. This normally involves a twin tank set-up. Where you start on derv then swap to pureveg oil once everything is up to temp, then before stopping swap back to derv to flush the oil out.
Another method involves heater everything up first and then starting on pure veg. This method seems to normally involve a Kenlow Hotstart to heat every things up to thin the oil.
Using BioDiesel made RME (Rape Methyl Ester) or conforms too EN-14214 EN-14214 is the standard for biodiesel now having recently been finalised by the European Standards organisation.
Depending on the quality of your Bio you can run it 100% apart from at the coldest time when mixing with derv can be recommended or mixing in an anti gelling agent.
No modification required with BioDiesel you could added a heated fuel filter to help things along but in most cases not required.
Only other thing is what engine are you running if it is NA 200 or 300TDi then should be fine. If its a TD5 then perhaps not Landrover only warranty a 5% Blend but you should be safe to 30%. That is is 30% biodiesel 70% derv.

Anyone know why rapeseed is the best to use?
