Now how in blazes do we know which ones?...it is not like they advertize...they should be made to say it on the pumps like they do with gas...that and the bio level as well....
U could fill a bucket of one brand and fill a bucket of another brand, lite a match on each bucket one at a time and record how many seconds till it burns or explodes. I would recommend u have a fire retardant suit on and a fire extinguisher on hand. Note: Don't try this at home.
