You're exactly right. AutoZone messed up the online and had the 5quarts at $4. I ordered 6 and the next day AutoZone fixed it. But they still let me pick up the order. And some of mine were dusty High Mileage. And some have black caps and some red.
Anyone know the part that needs replaced to stop this? I noticed that randomly while driving my lit up green D on the gauge cluster will glitch off momentarily. At first I thought maybe the ignition module was going or something key related to the key since the car's got some serious miles on it...
