I went into a Circle K store recently, and while I was waiting in line, I heard the cashier talking to a customer in front of me about whether or not he uses synthetic oil, and whether the cashier should use synthetic oil in his own vehicle. One of them mentioned that he used to use it in his Eclipse. When I approached the counter, he asked me if I used synthetic oil. As I was preparing to answer, a lady behind the counter, who had been doing paperwork, whirled around and said, "Synthetic oil is supposed to be for older cars," and said it would keep their engines cleaner or something.
I said, "I use conventional oil in my older cars."
The cashier said, "Conventional oil..." and laughed. I went on my merry way.
