I bought 6 packs of them for about 50 cents each in 1969 at the Mercury dealer. I liked the 12 oz can because it was the perfect amount for the 5 gallon steel gas cans we took to the gas station. shortly before we ran out of gas skiing etc., we'd pour 5 gal into a 6 gal tank that still had some in it.
Today I get the big jug and use a 16 oz plastic bottle for my measurerment for 6 gal. or 3 gal if I'm running 25:1
