As you all know diesel fuel is getting pricey, so I found 1 station in Phoenix that carries only B99 for about .22 cents cheaper than diesel fuel. Well i didn't care and filled her up! Now I am wanting to know what if any are the negative consequences to running B99 in the 6.0 power stroke? It's 90 degrees here now so cold temps are not even an issue. Is there some sort of conversion kits that I should get to run B99 all the time? The Ex is purring, I have driven over 100 miles since the fill up, starts and runs like normal......

 

The only thing I would do is change the fuel filters because the bio diesel will clean out all the junk in the fuel tank and fuel lines.

 

Give it at least a full tank before you change your fuel filter I started running B99 about 3 weeks ago and have 2.5 tanks through it and just changed the filter today. There will be no more smoke it will run smoother and be quieter. But I lost a little power and 1 mpg but that is ok the money is staying in the U.S. and I save $0.60 a gallon that’s about $105 a month for me!
