question on the new 08 and the 10% biodiesel even though it is said to only be at that much will it hurt the truck to run 75% biodiesel and 25%regular diesel ot will it totally ruin the trucks engine.

 

With the emissions equipment on these trucks I would highly recommend not running anything more than what Ford says.

 

WIth the DPF on I would not run it.

However with the DPF off, I am currently running 50% bio....I started at 20% and worked my way up....have about 2500 miles on 50% now.

 

Pahrump1 don't you have yours tuned also? Did it change your performance any?

 

Yeah mine has a 4" down pipe back with 4" RBP exhaust, BADP DPF delete tuning.

I honestly cannot tell any difference in performance....but then again I dont drag race, maybe on a dyno, or on timeslips you could see a difference.

 

I don't think the DPF is the limiter for Bio, I think it's the injectors. I think I remember reading on on of the many bio-diesel threads in this forum.

 

Bull$ hit....hell with a bunch of READING...I am DOING, and its perfectly fine...you hat a great many "I think's" in your post.....facts are what matter....not trying to bust your ***** but....


One day you guys gotta stop being followers and start being innovators...with the DPF OFF, and a tune to get around it, you CAN run bio...I AM running bio....I make it myself, and have been running it at over 30% for about 3500 miles...50% for the last 2500 miles....I dont care what someone "says" or what you "read" I am DOING, and to mean thats what matters.

 

ok thanks guys

 

I've run B50 in a totally stock truck w/o any problems. Considering that BD produces less soot, there should not be any issues running it with a DPF.

 

How do you make your own Bio Diesel?

 

Fuel Station at Walmart, Macon, GA says they sell 10% Bio. I found I got less than 1 mpg (LESS) using this fuel. The best fuel mileage I get is from fill ups at Flying J. Consistently better, and consitently the same.

 

Tan_hands - re making your own BD, there are several different options. No matter what, you're going to need a good source for waste vegetable oil; most folks strike a deal with a local restaraunt.

You can purchase an "all in one" biodiesel processor, such as the Bio-pro models, from Northern Tool or another dealer. They start around 7K.

You can make your own using the "Appleseed processor" concept for less than 1K. There is a lot of information available on the web; check out Utah Bio diesel supply. There is some misinformation as well, be sure that whatever system you choose, and whatever classes you take, will result in ASTM quality fuel.

The Piedmont Biofuels Coop in Pittsboro, NC offers classes in homebrewing BD. The classes are taught by one of the pioneers in the industry.

 

Keep us posted when you have around 20K miles. That's when I've seen injector problems. But if your batching your own you'll pay for the injectors. Just hope your not too far from home when it happens.

 

Is there any sort of Fuel Tax problem making your own? And can you imagine what my Homeowner Association would say? Or even the city of N Las Vegas if I started making it myself. And how long does it take to recoup the $7K for the Equip?

 

on p. 218 in the july, 2008 issue of "diesel power" there is an interesting q & a write-up on using bio fuels. i'm no motorhead so this is NOT my opinion. here is a brief of what the article said in case you didn't get the issue:

the article basically states that running more than 5% (B5) or in excess of 20 % (B20) will void your warranty if you have a mechanical failure. if you have have a 2008 diesel engine, it has high pressure injection systems that are designed to run on diesel #2 fuel.

the article also lists things diesel #2 fuel WON'T do:

-will not turn to gel inside fuel lines
-will not casue deposits in filters to loosen and clog the injection system
-will not eat up the seals inside your engine and fuel pump

the article also states that diesel #2 fuel is about 11% more energy per gallon, which translates up to 10% better fuel economy.

the article sums it up by stating some biofuels such as svo, biodiesel, and converted kitchen grease may cost less $$, and they may work better in older, low pressure mechanically injected diesels, but when it comes to common-rail diesel engines, peace of mind is a lot more valuable than a few pennies per gallon.......

personally, i'm not doin anything to void my warranty. i'm just gonna continue to be held hostage by our f-cking congress who won't let us drill and tap into the alaska and shale oil reserves.......... once the warranty is up, i will look into a dpf delete and tune...............be safe out there.
