Attention: TDR Forum Junkies 
im new to the site. Joined to get some information on biodiesel. Ive gotten imformation that was good but still varried a little depending on who you talked to. Maybe i can give a different point of view.
The truck - 2002 Dodge Ram Turbo Diesel 4x4. Quad Cab. 4" exhaust and Hi-Flow air intake. No gauges, no box, no nothing.
The fuel - 100% deep fry converted Biodiesel.
The results - Went from #2 dino diesel to 100% bio the night before a 400 mile road trip. Left before sunup that morning. Immediately noticed, no smoke. Usually at night I can get into the throttle and see cars scramble behind me for a more visible line. A little puff on startup and thats it. There was a loss of power. Thought maybe its because my tank was fulll and the truck was "heavy" or id convinced myself it was going to run different but it did. Quieter, all the way around. the engine (((rattle)))) was a little quieter and the exhaust at idle and under load was quieter. My Mileage (6 tanks later) shows to be a little worse on the highway and a little better around town. yep... . thats right, worse at 2k rpm and 70 mph than dashing around town.
The oberservations - I think all the performance changes can be related to the BTU load (except that mileage thing, cant explain that one). The BTU load per gallon of biodiesel is about 8. 5% less than #2 dino diesel (saw that fact in several places on the web). That would explain the lack of power, the lack of exhaust noise and engine rattle. The smaller the explosion the less the noise it makes. The cetane (lubricosoty) of bio is better than #2 diesel so I imagine in the long run my engine will live longer. Odd fact thought, when changing the fuel filter with diesel the fuel and smell is difficult to get off your hands. BIO seems like its water soluable, clean as a whistle with little effort. I was told to change the fuel filter often using bio, not because BIO clogs it, but because the #2 diesel leaves deposits in the fuel tank and lines. Bio breaks it up and moves it on down the line. If it clogs the fuel filter, the lift pump can go then its all down hill. Im changing that filter often.
The future - Runs good, the decrease in power and sound probaly helps me in the long run. Im not in the throttle all the time feeling the power and hearing that throaty growl from the exhaust. Ill run this stuff as long as its cheaper or the same cost as #2. Luckily here in Marietta Ga its still cheaper than diesel. Ive changed the fuel filter 3 times and plan on changing it on an accelerated schedule until I get a fuel pressure gauge.
The reccomendation - run it, run it, run it, Make sure the vehicle is newer than about 2000. Nitrile rubber doesnt react well to this stuff. Most newer cars are BIO frendly right out of the box(car). My Bio dealer says he sees a new face every day so word is not getting around, its gotten around.
Good luck...
