5.85 USD/gallon is: 1.33€ / L or 2.10 CAD / L.

Cries in actual 2.60/L CAD.

I am feeling it for folks who use oil heat (diesel with different tax structure) in areas where there is no natural gas.

Home heating oil runs at about 75% the cost of diesel. The storage tanks are 275 gallons/1100 litres, so a fill-up, which might happen four to six times in a winter, would be extremely painful right now.
