I changed the oil in my 2016 Nissan Rouge at 1650 miles using Castrol GTX Magnatec 0w-20 synthetic and the specified Nissan oil filter. It's been a few weeks since I last checked the oil But I checked it today and it appears to be red as almost like tranny fluid. I have never seen oil turn red before. The antifreeze is a blue green color so I don't think there is a head gasket problem. The transmission is a sealed CVT unit so I can't check the fluid and I don't know what color it is any way. The car has 4800 miles on it and the oil has 3100 miles on it. Since I planned on changing it at 5000 miles, I made an appointment with Nissan for an oil change and tire rotation for Monday. I'm hoping it's nothing but I will mention the oil color to the Nissan rep. Anybody ever see this?
