Fluid in my 2010 GMC turned black in year 3. We all know what it means when clear oil does that in the absence of combustion … BUT, there is still lots of heat and pressure. Once I started to flip a few ounces once in a while
(Even with a site hate brand) … stayed clear for the next 5 years. Matter of minutes and a few bucks.
