This is my very first post on any forum so please be patient with me if I screw this all up.
I have a number of questions related to boidiesel, but will need to mention some background info before I get to them.
I recently sold my ‘92 Ram W250 5.9 and replaced it with a ‘08 Ram 2500 6.7. I almost cried when I watched the old truck drive away, but it had to be done. Although the engine would have probably lasted for years the rest of the truck was falling apart. I neither had the time nor the resources to repair all its issues. The ‘08 Ram is a beautiful truck, but I still miss the ‘92.
Anyway, I’ve been wanting to home brew biodiesel for a long time, but never got around to it with the old truck. However now with the absurd diesel prices it’s become a necessity. Dodge claims the 6.7 is compatible with B5 and up to B20 in fleet and military trucks, but I want to run B100 or close to it. It wouldn’t be cost effective otherwise when considering the price of a home brew system and producing the fuel. My concerns specifically revolve around the DPF’s reaction to B100 and possible oil dilution issues. Apparently during catalyst regen the engine injects fuel during the exhaust stroke there by passing unburnt fuel into the exhaust where it ignites in the DPF creating the heat necessary for the collected soot to chemically break down. This additional fuel injection causes some fuel to work its way thru the piston rings and into the crank case causing fuel/oil dilution. This dilution issue is supposedly a greater problem when biodiesel is involved. Something to do with the methanol content.
So finally here’s my questions:
I like to hear form anybody who’s run high percentage biodiesel in their 6.7's.
-How long/How many miles?
-Under what conditions? (Towing/City/Hi-way driving)
-Performance/MPG?
-Any CEL’s , Full catalyst warnings, or other issues?
-Are you using Home brewed or Commercial biodiesel?
-If home brewed what type/brand system?
Answers to any or all of these questions would be greatly appreciated.
I apologize for being so long winded and asking so much I just don’t want to destroy a fifty thousand dollar truck.
