Currently have pu in 09 Hyundai accent with 10000 miles. I drive to and from work 5 miles each way. On the weekends I do 30 hwy miles to and from the fishing hole at least once. The engine is a 1.6L dohc cvvt with 3.48qt of pu with a Hyundai filter. I will change it for warranty reasons as suggested by Hyundai. But warranty aside, what would you feel is a safe oci with this set up?
