Long Long Time ago---
When I first cruised main street with my 50's - 2 door Chevy 6 banger upgraded to a 235 cu inch, full oil pressure motor, 3 speed on the floor----
We would scrape up $1.00 and buy 3 gallons of gas.
It is not the fair amount of profit that the oil companies make, it is the low value of the dollar that makes it expensive. The governmental politicians print money to keep them selves in office, the dollar is based on vote getting, not on any real value that common sense would dictate.
Just my X inflation=
