I have 6 for mower gasoline for total of 30 gallons. (4 acres to mow). 4 yellow ones for diesel for tractor and b/u generator. 4 other Nato standard 5 gallon gas cans, and about 5 or 6 cans of varying sizes without the little yellow plug for the end. . . . . Of course no one sells just the end cap . . . . and the new (SAFE) fuel spouts are a PITA and break often as well . . .
Forgot one dedicated 5 gallon gas can for non-ethanol gas for weed wackers, backpack blower, and pressure washer . . .
