Can a DSE or 300TDi run on veggie oil?

What about common rail diesels such as the BMW 3.0L TD6? I have been told that they cannot run on biofuel or veg oil. Is that right or wrong?

Ran a Toyota 50/50 svo/Derv for years, just put 30Lt derv in the tank and topped it up with 30Lt Rape oil. Ran smoother, quieter and more miles! Nippon lift pump is a copy of the Lucas square body type so everything OK. I never found the need to mix it externally, first few corners and excess fuel return system did that!

Common rail and SVO do not mix, steer clear or expect trouble.

Old farmer fried told me years ago that he filtered it through a loaf of bread ! Said he dug a hole out of the top and just poured it through.
No idea if it works or if he had maybe been drinking the stuff.

I did get told this by an old "boater" but the idea of all the bread in the tank didnt convince me, i suppose tho it could be filterd lol...
In the interest of science il try it and let you no.

might give it a go at 50/50 in my 95 2.5 dse
but will build up to it gradually.

Veg oil seems hard to come by at the right price now. It hardly seems worth the effort

My local Asian shop has fresh oil in 20 litre drums for £20.00 quid a pop, so saving about 40p per litre. I run my 300TDI on 50/50 Derv/Veg. Not noticed any difference in performance or economy.

Been running 50/50 mix for last 3 months, no problems thus far. I don't use waste oil only fresh.

Hi, my P38 2.5 DSE languishing in garage awaiting replacement FIP - garage have removed old pump which was looked at closely by refurb company - they think it has been damaged by using veg oil mix. Going to cost up to £800 with fitting on top if I can't find one from breaker's yard. Word of caution only...
