Today I found out the overflow coolant bottle is full of oil on my BMW motorcycle. Given how that bottle looks like, with no markings what so ever and that the actual oil fill cap is under the seat, I'm not surprised some knucklehead topped it off.
But what stumped me was how black the oil was in there. Unless the guy topped it off with used oil, I never expected it to look like this.
At first I thought it was some sort of additive in there or something.
Fortunately there was no evidence of oil in the radiator, so hopefully the system is not damaged.
Here is the mess I drained
Here is how the overflow bottle looks like, total facepalm on BMWs part.
