i would not run strait bio due to not knowing what lubricity or cetane levels are. bio is a pretty complicated mix and to run it strait i would be leary of causing injector problems......

as far as strait veggie.....to run it only....and poor it in your existing tank can cause problems. first off you have to make sure your filtering is very fine....but even then there is cold start issues......if you run a dual system with separate tanks and heated lines....start on #2 and then switch to WVO once the coolant has warmed the heated lines.....you are ok.....my girlfriends dad has been runnign strait WVO with separete fuel systems for a while with no problems....there is a lot to it and you will really need to do your research.......Marc

I just threw this out to see what other people thought. I started running Bio in my 99 about 3 years ago I bought it from a local fuel supplier its a 50% blend and is made from soybean oil. No trouble yet. I have contacted the national bio board several times getting different info when I switch farm tractors over to run this stuff. Most of it to do with replacement of the rubber parts to Viton. I have thought about making the stuff myself in the garage and they tell me it is possiabilty but would probly need to invest a couple thou in chemistry supplies.

bio does play heck on rubber parts...but the problem is you cannnot count on it for lubricity and that can cause other parts such as injectors that rely on the fuel for lubrication to fail also......a 7.3 can run very well on a 50/50 blend from what im told...but i woulndt go any more bio than that. that is one of the benifits of WVO is it has great lubricity properties and has a very consistant flashpoint.......but it is tougher to run your truck on and to do it properly it requires basically a whole seperate fuel system between the head and the tank........Marc
