    chillman88, my order of operations is:

    -let acquired WMO settle out. The longer, the better.
    -boil out the water
    -heat it while running thru the centrifuge. I usually heat it between 80C and 110C (176F - 230F)
    -after it's centrifuged, I mix it with 10-15% RUG and maybe another 5% biodiesel.

    I don't even mix it with diesel now. It seems to run ok in both my IDIs and Powerstrokes. I do get the engines up to operating temperature on diesel before switching to the WMO cocktail. The engine also gets run on diesel before shutdown to purge the WMO. I also run Seafoam in the diesel tank to help de-coke the injectors.

    More crap pulled out of the same batch of WMO after another 12 hours of 'fuging! :eek:

    This is why I don't have a fixed time on the centrifuge. I just run it through the 'fuge until I think it's clean enough.

    Will you centrifuge again or run it?

    YJMike92, the centrifuge pulled just as much crap out yesterday. :p I will keep centrifuging it until it only has a thin layer of crud. I've had batches that have taken 48 hours on the centrifuge. This looks like this batch might take that much time or more. :rolleyes:

    As for mixing in the RUG, I just pour it in the barrel of oil and then run the pump to recirculate it for a few minutes. I also recirculate it in the barrel a few minutes before I fill the truck tank from the barrel. After it's in the tank, I don't worry about it too much because I normally use it right away, and also when the engine is running, the fuel gets recirculated in the tank anyway.

    I've tried recirculating with a pump, maybe I'll try that again.
    My most recent attempt was putting 5 gallons of RUG in the bottom of a 55-gallon barrel and allowing the oil from the centrifuge to drip into the barrel. When the barrel was about 50% full I put a 1/2" pipe with an agricultural spray nozzle at a 90% angle down to the bottom of the barrel. Attached an air hose with a regulator and bubbled air through the solution. I have not tried that barrel of fuel yet. It seems the gas tends to lay on the top of the oil if it is not forced to mix.
