curios as to how long it will store for, There is a large commercial processor near me that will sell it at 3.70 a gallon bulk, if I pick it up, taxes included. Petro diesel with additives can be good for up to 10 years, if I can get a year out of bio diesel I'd be good.

The plan is to get 4, 55 gallon drums and have them filled roughly every 4 months. (pump prices for petro d are around 4.10)

 

I've been making biodiesel for about 8 years now and I've used fuel that was over a year and a half old with no problems so you should be okay. just keep it sealed and out of the weather.
