Somewhere around 1981 or 1982 I had a Honda Prelude that I had bought new. I guess a couple years after that I took it to my service guy to get the valves adjusted, I believe. While it was there I had him change the oil. I usually change oil myself, but it was winter and I was already there, so I had him do it. It was a small garage and I had gotten to know the guy a little so I was able to hang around in the garage while he was working, unlike most service places today. Anyway, after changing the oil and starting the car, he turned it off and pulled the dip stick. He was surprised by what he saw. I said 'what's wrong?' He replied that the oil was clean. Now I was surprised. I said 'why wouldn't it be clean? You just changed it.' He said that most of the cars that he worked on, after changing the oil it still showed black on the dip stick. I was surprised by that.
Now back in the 80s and even later I was changing my oil every 3000 miles like I was told to do as a car enthusiast and maintenance minded driver. I guess most drivers couldn't be bothered with their oil. It's probably still true today. Anyway, I never forgot that incident.
