Running on Vegetable oil ?
Discussion
I know this is an old thread, but i'm just about to try and run my 1999 A4 on oil, mixed very roughly, 50/50, before going more to oil.
These audis have fuel heaters built in before the pump to warm the fuel to about 70 degrees, to allow running diesel to -30 degrees, according to the handbook.

I did this about 11 years ago.
I had a two tank system in my Pug 405 TD using filtered WVO (waste veg oil). It ran smoother and quiter.
Did it for two years and I cracked the block, after not putting anti-freeze in it!
I then ran a Merc 190D with SVO (fresh veg oil) oil straight into the tank. Ran it for 12 months until I sold it.
Apart from the mess and hassle of using WVO, collection, storage, filtering etc, the price of SVO started to go up so I didn't bother after about 2004.
That BMW will be fked very soon.

I had an Alhambra no pd, ran on veg oil and a twin tank system started and stopped on deisel. Turbo blew after 25k and the engine was never the same, smoked.
Bought another one ran on a mix, low in winter high in summer. Engine blew. Pattern emerging. Engine oil changed every 3k too. This engine does not like veg long term!

Interesting...I stopped with veg a few years ago since I was using one container to hold veg before filtering and also heat before making into biodiesel. I got fedup with clogged filters due to the palm based oil that I was making into biodiesel because of not cleaning it out inbetween.
Wonder how the XUD9 engine would have got on if it was still on veg now....
What's the deal with Bio Diesel (B100) and common rail diesel engines - many biodiesel websites would have you believe that you can use B100 as a direct replacement to diesel, with the only concern being the fuel filter clogging up from the increased cleaning properties of the biodiesel cleaning out your fuel system.
Is that true, or are there other concerns?
