I have decided to put my 2010 Tucson on a 6 month spring/fall OCI to match my older Accord. The Tucson will see an average annual mileage of 13,000 with a pretty even split of highway/city street use. The 2002 Accord which this replaced was on a 5k oci on dino and a Purolator classic filter. Because I am not too familiar with the Hyundai 2.4l engine, my question is do you think it would be wise to press some conventional (PYB/QSGB) out to 6500 miles, or should I move up to synthetic? I am probably going to go with either a Wix or a PureOne filter. Thoughts??
