Went to an Autozone today to buy some Havoline full synthetic 10W-30. The manager told me if I bought an oil filter, he'd sell me all of the oil for $1 a quart. One Motorcraft FL820S filter and about 120 quarts of Havoline and Valvoline synthetic 5W-30 and 10W-30 later and I walked out of there a very happy man. Of course I won't have to buy oil again for about two years. Normally, I HATE Autozone with a passion. But not today.
