I recently ran into someone at a local 4x4 shop and he mentioned that they have been doing a number of conversions on diesels so that they could run on bio and/or vegetable oil. I am going to talk with them somemore this week but was wondering what you guys had to say about it. I am currently looking at purchasing a new 6.0 or 6.4.

Any info would be appreciated and any suggestions on what to ask the 4x4 shop.

Thanks
