The green stuff is on sale this week at AutoZone. $4/qt. Stock up if that's your thing.

Update

I work there. On Wednesday, when I was pricing out oil, the "$4/qt special deal" signs were not out. They must have been posted on Thursday. This morning, I went to buy some, and it rings up at $5/qt! Apparently, the sale began a month ago (though there was no way for our customers to know about it) and ended a week ago.

Thank you, my stash is down to about 20 quarts. The outback will be getting a fresh shot of GC this weekend.

I bought my pile at $4.99. Cleaned 3 local auto-zones (12qts). Plan to start using it soon. I am tempted to buy more, but have 50 qts of oil for 2 cars and a boat. This is what BITOG will do to you!
