I went to Meijer to pick up a single quart of motor oil to keep in the trunk (I used the last one up.) Mobil Delvac 1300 15w40 was $10 for a 2.5 gallon container. Needless to say, I bought all two of them. My hands were full, so I couldn't carry a single quart. Is it sacreligious to put Mobil oil into a Castro container?

Cliff Note: Man buys motor oil for $1 a quart, and is happy.
