I just pumped $100.00 C. ($80.00 US) of 87 octane fuel into my 2015 Dodge Durango today. This is the first time in the 5 years I have owned it that I have done this. Regular fuel was $1.30.9 per liter at this Ultramar station. Other stations in town were at $1.36.9. 4.5 liters = 1 Canadian gallon, so that makes it $5.90 per Canadian gallon. 4 Canadian gallons = 5 U.S. gallons. $5.00 Canadian = $4.00 U.S. So, doing the math, it would be like $3.77.6 US per US gallon. Sad thing is, I was still about 3 gallons off empty!
