    It’s good to think about what is put in the water from running old outboards. What you are seeing is normal but you usually don’t see it as it’s injected below the surface (mostly) and dispersed. The barrel retains it for your viewing enjoyment. Agree with installing a recovery system on the crankcase drain, and using oil that is (supposedly) biodegradable.
