How Big can a 5.2 get?

Our gas prices have been dropping this winter which is highly unusual. With an exchange rate of 1.33; the price equivalents of 87E10 are from as high as 6.49 per USg last fall, to currently 4.79 per USg.
Just to compare; a 2 liter bottle of Coke costs the equivalent of 8.96/USg.
And jug of milk is 9.68/USg equivalent, of which I buy 3 per week,minimum, of which I drink 2 by myself. I love milk!

Might be the surplus of American oil, first time in history the U.S. is producing more oil than it needs and the oil companies don't know what to do besides keep processing and selling more of it. Which isn't a great idea since there are still leaking pipelines and offshore rigs that need to be fixed but that's another discussion lol.

Wait you're saying a 2-liter of Coke costs almost $9 in Canada and here I can buy one for like $3? And a gallon of whole milk (milk fat is good for you if you're active and eat heathy) is $1.99 before tax at the local grocery... I sure hope your minimum wage and mean household income is higher than ours!
