2011 GMC Terrain 2.4L 4cyl GM-Dexos 5w-30 8,066mi on oil, 24,976 on vehicle. (3rd oil change). Oil/filter changes have been done by the dealer.
Unfortunately, I didn't have the first two oil changes analysed. I have ran the oil until I usually get to about 20% of oil life as indicated by the dash readout. I became concerned about the engine after receiving a notice from GMC about an issue with poor plating on the balancer chain. As explained in the oil analysis from Blackstone, the metals are high.
I am debating if I should bring these numbers to GMC or wait and do another oil change and see where the numbers are then.
I have also posted the letter from GMC about the issue.
Any thoughts would be appreciated.
