biodiesel question

[04hdfatboy]

What do you guys think of using biodiesel. The main reason i am considering it is because it has higher cetane and higher lubricity. If so what percentage would be good to use? Do you think it will cause me any problems. Thanks for any advice. Here is the website for the company i would use.

I have been using Texaco with 5% biodiesel (highest % recommended for the 6.4.) I find that it makes my truck run better with less injector noise. I have run Diesel Kleen in every tank.

I have read that there are potential concerns with biodiesel knocking debris loose in the fuel system and causing issues. I am not sure if this is with higher % biodiesel or just in poorly maintained fuel systems. I would be interested to hear from some other members and their first hand experience.

How could i find out if the diesel i use is a certain percentage of biodiesel? Also are you deleted? I was thinking of running 20%. Would that be too much?

The Texaco and Exxon I go to say "Not to exceed 5% Biodiesel" on the pump. I am deleted running H&S tunes. I get quite a bit of injector noise running Shell or Exxon diesel when my truck is cold. I noticed a difference with the Biodiesel. I am a little nervous about running more than 5%, but I bet there are some guys on here that have tried.

From what i am gathering from research i think i will stay away from biodiesel. Thanks

From the owner's manual -

Diesel fuel containing no more than 5% biodiesel may be used. To help
achieve acceptable engine performance and durability, it is important to
only use biodiesel of good quality in your diesel engine. At a minimum,
the biodiesel should comply with ASTM D6751 or an equivalent
specification.
Use of biodiesel in concentrations greater than 5% may cause damage to
your vehicles fuel system components such as fuel tank, fuel lines, fuel
pump, fuel sender and fuel injectors. Concentrations greater than 5% can
also cause fuel filter restrictions that may result in a lack of power and
or fuel pump and fuel injector failure.
Look for a label on the fuel pump to confirm the amount of biodiesel
contained in a diesel fuel. Biodiesel content is often indicated with the
letter “B” followed by the percent of biodiesel in the fuel. For example,
B5 indicates a fuel containing 5% biodiesel. Ask the service station
attendant to confirm the biodiesel content of a diesel fuel if you do not
see a label on the fuel pump.
Biodiesel should not be stored in the fuel tank for more than three
months. If your vehicle will be parked or stored for more than three
months, then your vehicle should be drained and filled with a diesel fuel
not containing biodiesel.
During cold weather, if you have problems operating on biodiesel, you
may need to use a diesel fuel with lower biodiesel content, try another
brand, or discontinue the use of biodiesel. Biodiesel use may affect the recommended oil change intervals. Refer to
the Special Operating Conditions section in the schedule
maintenance guide for more information about oil change intervals and
other maintenance when operating on biodiesel.
Biodiesel fuel is a product that has been converted from renewable fuel
sources, including vegetable oil, animal fat and cooking oil. Raw or
refined vegetable oil, animal fat, cooking oil or recycled greases should
not be used.

There you have it.
