Plain old diesel fuel may be fine if you have access to clean, high-cetane, lubricating diesel fuel. If you do then you are very lucky. MB recommends a minimum cetane of 45. Most US diesel fuel has a cetane of 40. My favorite additive is the Amsoil Cetane Boost and it makes a huge difference in engine noise. As for lubrication I like to use either B5 (5% biodiesel) which is available locally or one of the fuel additives available in any McParts store.

Austin, can you elaborate a bit more on your problem? Did you have waxing problems with your WVO? I checked out that site but there doesn't seem to be a way to buy it (like adding it to a cart).
