Those 275 gallon fuel oil tanks can be had for free or for cheap on Craigslist.org if you watch the ads for awhile. Right now there is one for $45 and another for $50 & was recently one for free on the Portland, OR Craigslist. People change to natural gas or other heating systems & have a tank to get rid of.
I just use 5 gal. cans & only have them fill them to 4 gallons so they won't be so heavey & so tippy. Use them for my airplane which requires getting on a ladder & for my tractor. My airplane usually takes about 10 gallons at a time, the tractor less. Not much of a hassle, really.
