As subject states, 2011 Durango 5.7L Hemi. 118k Miles on SUV, 3k miles on oil. This is the new D1G2 Formulation. Filter was Fram TG2 which will be pasted in oil filters in next 48 hours. Makeup oil is .25 quarts of Pennzoil Platinum HM. Both oils are 5W-20. Not sure why [censored] thinks I used 5w-30. Oil was in service through NE Winter. Vehicle was ne to us in July. Fixed massive oil loss/consumption problems before this OC. No cooolant so headgasket is good. Low copper so Main bearing should be good. Double the average on Iron. Thinking about trying PP HM for a full OC as I dont like Iron that high. TBN was much lower than I expected after only 3k miles at 3.0. I was hoping to get longer intervals if I void my Valvoline Engine Warranty. Thoughts?
Edit: Oil was Valvoline Full Synthetic W/ Maxlife D1G2 Formula new Easy pour bottle.
