Just read all nine pages on this topic and I changed the oil last month(7800 miles)on my 2015 SHO non PP with 22500 miles on the od. I use Pennzoil 5W-30 conventional oil and a Fram Tough Guard oil filter. I will do my next oil change when the oil change monitor tells me to. Some thoughts on oil color: You should check your oil level when the oil is cold and you should check your oil for color when the oil is hot. If you do this you will see that the oil color when hot is much different then when you check it cold. Cold oil is very dark at even 3000 miles but still very clear hot at 8000 miles. Some thoughts on Anti-Freeze: Prestone has an Anti-Freeze that you can use in any model car and with any color anti-freeze. Just saying
