Sounds like a good price for a(n) (AutoRx) flush oil.
I hit the Shucks in Lynden, Wa yesterday. Boy, what a suckie oil selection. Really sucked because they were out of 10 amp blade fuses, my original reason for going.....sorta reminded me why I don't shop there normally. (Although they DID have a turn signal flasher for the Volvo when mine dies the coldest day of this last winter)
