A red oil indicator light made me take my car to the workshop on Saturday. Oil level was ok, but it was leaking oil onto our driveway. Our friendly car dealer saw to it immediately and said it was a bust oil pressure switch. Knowing little to nothing at all about cars, I raised my eyebrows appreciatively and inquired how long it would take to repair. To cut a long story short, I was given an ersatz car and drove home to tell the story. This evening, when I fetched my little girl from school in the missus’ car, something was rattling. I wondered out loud what it may be, and guess what my seven year-old replied: “It must be the oil pressure switch”, and she grinned. It took me a while to stop laughing. ;-)
