A quart of name brand 5W30 is still about $2.25, and has not come down
as crude prices have fallen. I realize that crude is just a small part
of the cost of producing motor oil, but apparently it does not respond
to decreases in crude prices at all.

Soon I will have to do some 0W-20 oil changes and that costs about $6
per quart.

You got the government you voted for.
