I have 13,xxx on my 2004 Acura TL. I just changed my oil with M1 5W-30 at 13,000. I also added 4 oz. LC during the oil change and used FP60. I also added 1 bottle of 8 oz. Red Line Wet Wetter to my radiator. After driving for several hundred miles, approximately 300 miles, I checked my reserved coolant tank and I saw some weird mixture. It looked like oil/water mixture. Do you think the wet wetter cause this problem or oil somehow got into my cooling system? I'm not sure whether it was oil, but it looks like oil droplet. What do you think?
