This rolled into the shop today with an oil change reminder sticker indicating 11,000 miles on the OCI. Mileage at service was hand written on the sticker along with next lof due. No question there. Aftermarket shop did last lof. Car was here for 2.4 liter connecting rod noise inspection and passed inspection. 2011 Kia Optima 2.4 GDI. Got an oil and filter change after inspection with OEM filter and Mobil conventional. I do realize 11k on a jobber filter is blasphemy! Submitted purely for your amusement. Enjoy.
