I have another 16 oz bottle of the type with the built in 1 oz measuring cup, like the bottle that the Bio-Bor comes in. I mix 1 oz of Bio-Bor using the built in measuring cup to 15 oz of fuel and this mixture goes into my dispenser bottle. Now it is a simple task to use the built in measuring cup add 1 oz of this mix to a 5 gallon jug of fuel to have the correct dilution. It is also easy to travel with this bottle to treat any fuel I have to buy at an event. That one 16 oz bottle will treat sixteen 5 gallon jugs of fuel.
