I have a 2020 Jeep Wrangler JLU 3.6 v6. I got my latest oil analysis back and iron has went from 16ppm to 28 ppm. Both intervals were around 5k with just over 200 miles difference. The other variables is late summer/Fall on the 16ppm and all winter for the 28 ppm sample and approximately 200 more miles. The other variable is I didn't drive my Jeep the last month before the 28 ppm sample. It would sit for days without being driven because I got car from my job to drive. My theory is that due to the days of sitting without running caused dry start up wear plus wear numbers trend up in colder weather? The rest of my numbers were spot on and nothing noted by Blackstone. Your theories?
