Racetrac Diesel Contains Biodiesel
I'm a newbie to diesel ownership; naturally, I read the manual upon buying my new (to me) '08 F350 just as a I do with all vehicles and such. It read not to use biodiesel whatsoever. While at the local Racetrack pump with my company owned F150 last week I noticed the decal next to the handle read, "contains 6%-20% biodiesel." Other than making a mental note to NEVER source diesel from Racetrac, I found it clever they charge the same price for the blend that all other stations do 100% diesel fuel. I've seen some posts that biodiesel contains positive lubricity properties. So what's the final verdict of how much, if any is too much?
I'm not sure whether or not the blend is due to region or if others have noticed it elsewhere. I'm in Florida.

Did you read the Diesel Engine Supplement?
BIODIESEL
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.

My local Racetrac in FL recently changed the label on the pump to acknowledge they may have biodiesel blend. I will no longer buy from them as my Mercedes diesel and soon to be F250 6.7L both say not to use biodiesel over 5%.
I imagine all modern diesel engines do not allow the blend?????
