We are planning a trip to Canada.
I just checked Gas Buddy for local prices.
The cheapest I could find was one Chevron station, which I like, @ 141.9
Now at today's money conversion rate, that comes out to $1.089 US per liter.
1 gallon [US, liquid] = 3.785 411 784 liter
3.785 x 1.089 = $4.12 per gallon!
