I know that this is all over the site but I am trying to get clarification on running b 100 in Duramax. I have two 07 duramax trucks. Both are the original body style / not the new body. I believe that I am correct that neither of these trucks have the DPF. Both of my trucks are already out of warranty so that is not an issue. I would like to know your thoughts on running b100 straight. I have run 3 tanks of straight b100 with no issues.
I am interested in this as I can get b100 delivered to me for $1.72 per gallon from a local fuel distributor. At current dino prices, I'm saving .56 per gallon.

Any thoughts would be greatly appreciated.
