60 hrs into my first OCI with Valvoline Restore and Protect. Changed the Cart filter @800miles on the 16 Jeep Grand Cherokee, looked fine. I should hit ~3k miles at 90 hrs. Will probably change at that point and then go to 4k oci the nest few times. 113K miles or about there now. No known sludge issues, but it did quiet down a valve lifter after a short time into this first run. I'm running the 5w30 Valvoline Restore and Protect , and usually run a Xw-30 oil.
