2022 Frontier SV with approximately 12,000 miles, never any issues other than the usual diff cover leak and the brake light switch. Driven on the weekend and mostly to tow my 5000# camper. I decided to buy an oil filter cutter and look inside the last 2 filters. Both had a couple thousand miles on them and were changed due to time not mileage. As you can see there were a couple metal flakes in the filters. No engine noises that I can hear. A previous oil analysis showed high levels of copper and I will do another analysis at the next oil change. I still have the Nissan powertrain warranty until 10/18/26, should I be concerned?
