that is the biggest load of BS i think i've heard today. the Biodiesel has several times more lubricity than low-sulfur diesel. im not an expert on it, so i dont know about the detergents, but it does clean up the areas where fuel touches very well. there is less BTU's per gallon in a gallon of Biodiesel, opposed to #2. this means the mileage will suffer a tiny bit if any. i just filled up my truck with biodiesel and it came out to a mixture of b73.

in all truth biodiesel is alot better for the engines and injectors, it is just that ford doesnt want to hear this because they know it is better for the engines and that means less service work for them.

the engines were trashed due to something else. they found biodiesel and pointed their finger at that right away because ford only warrantied b5 or less.

i would be screaming "magnusson-moss" to my dealer if that was my truck.
