Is there a place I can send out samples of fuel to see what rating it is.

Depends on what you're trying to test. For any fuel (including dino-diesel), they test many different parameters.

the ones for biodiesel that are most important seems to be:

water and sediment (you already did this, from your other post)
conversion (ie that the fuel is not contaminated by 'monoglyerides' and 'diglycerides')
methanol content (not an issue for you if you water wash which it sounds like you do)
acid number (this is like the titration that you do for oil, not usually a problem unless you've used acids in the water wash for some reason or the fuel has been in storage for a long time)
residual lye and soap (also probably not a big deal if you water wash)
