I filled up my little car's gasoline tank this week, I do this about every five days because I drive, round work trip 50 miles a day.  Filled the tank using not my usual special (read expensive) gasoline, but something called regular.  Cost was just over 40 US dollars. It takes over $70 to fill the truck's tank.  Well, that was a week and a half ago.    I've seen some people now paying over $90 for a fill-up.
