Bio Diesel Concerns
Well from my 2 years of diesel mechanic experience I have seen some interesting results of running Bio. Now there were a couple of guys that were running What I think was Bio but I am not sure if they were actually making bio diesel or just running filtered WVO. Any way on guy was running a GM 6.5 and the other guy was running a IDI 7.3. They must of went through 2 injections pumps each. They had all the heaters and even a preheater 2" before the inlet to the INj pump. I was told by our local Injection Pump Rebuilder that Bio is to thick for these rotary pumps but it is okay for pumps like the ones on the older mercedes because they are lubricated from engine oil also?
So my question, is it really wise to run bio on a engine that has a fuel system that was engineered to run on diesel. Obviously the basics of the diesel engine alow us to run BIO but I'm slightly concerned with our fuel systems with tighter clearances that were engineered for Diesel.
So the owners manual for my 05 6.0 says I can run up to 5% bio B5, I have read that some are actually running up to B20. I'm just concerened about really fouling u a $50,000 truck. And If I made my Bio and only mixed it at 5% would I really be saving any $ after purchasing a processing kit?

They were running veggie oil if its thick with heaters.
Biodiesel is a direct replacement for dino fuel. 6.4 do not like bio because its got too much oxygen and throws some sensors off. You have to mix it up a lil.
6.0 love running it just fine.
Do not confuse veggie with biodiesel.
Biodiesel will disolve the old seales from pumps and orings on the older diesel without viton seals. Like disolves like qualities. There are kits to change that.

Two things come to mind. If the trucks had fuel heating systems they were most likely using WVO. Using a heated WVO system works OK as long as you prepare the WVO properly. It must be filtered very well, and ALL water removed or it will cause problems.
If they were using biodiesel and heating it that will cause oxidation and polymerization of the bio which would cause IP failure.

Thanks Guys! Since spring time is here I think it's time to start adding more bio on each tank. It was 32 deg f this morning but I think it is the end of the cold season. The owner/manufacturer of the bio station I get my bio from said to use b50 to b75 till it warms up. I hear about guys using b100 in cold climates year round and I was just wondering how they do it or if they are just full of it.
