Today I took the rover for a drive and decided to open up the oil cap, and found a disgusting goo inside :shock: . It sits outside now since I don't have time to scrape the windows on my daily driver in the morning. The temperature has been getting pretty cold now, especially last night with the low around 32F. So I am wondering if this is just condensation... I HOPE. I took out the dipstick and did not notice anything out of the ordinary. So I cleaned the cap and put it back on, and drove it some more, and I found some water droplets on the top, but not coolant (It was very clear water), I'll give it a whirl again tomorrow. Let me know what you think.
