Prior to Y2K I purchased several empty 55 gallon drums,cleaned and filled them with #1 kerosene(clear). It wont break down. I am still using it seasonally and am down to approx. 30 gals. I also purchased four 6gal.jeep gas cans W/bonus 2 1/2 gal.cans attached. I use the grocery/gas discount promos to maximize savings when filling them. I use the stored gas to refill my tank while earning points until I need to refill. Store gas in building away from primary residence.
