The Dept. of Agriculture has a big research farm in my neighborhood and they have several big farm vehicles that they claimed to be run on soy and other veggie bio-diesel. They even had a passenger bus that took people on tours, etc. and they called it the "Bean Bus. It was too tout the use of bio-diesel as another one of the great green alternative fuels. It even had a saying on it that said "This vehicle gets 290 miles per acre" or some such nonsense.
The funny little secret was that they ran it on good old petro diesel because the bio-diesel stuff was plugging up the injectors, filters, and other fuel system components.
If the Dept. of Agriculture won't use bio-diesel, I would think twice about putting it into my rig.

Alamosa, Co., just up the road from me, has their own Bio diesel plant and there is a public pump (Alta fuels) that sells it for $1.50 a gal.
I've been told that on my '94 Dodge that the fuel lines are not compatible but that the newer ones are OK to use Bio.
The diesel engine manufacturers will never condone the use of homemade fuel in their engines. They don't want the liability if something goes wrong. They are also under pressure from the Feds. When someone makes their own fuel they are not paying any road tax which is the source of revenue for road construction and improvements.
hipower wrote: The pumps at the FJ in Brunswick, GA several weeks ago had a sticker on them that stated the fuel contained up to 20% bio-diesel. That was at the RV islands, not sure if it carried over to the truck pumps, but find it hard to believe that they have the ability to segregate the supply tanks to that extent.
Bio-diesel and waste veggie oil are two different things. The OP was asking about waste veggie oil. You can think of veggie part of bio-diesel as being refined waste veggie oil. You can run it filtered or as biofuel. Filtered has to be heated before you can run it.
And waste veggie oil is the used cooker oil from restaurants. Most restaurants contract with someone to remove it. You can just pull up and pump it out. If the guy who holds the contract catches you doing this you can be charged with theft. It had become very difficult to find a good supply of wvo!
