How often should the oil be changed on a 2008 Toyota Corolla and does it require synthetic oil?
oil change on 2008 Toyota Corolla
I change my oil and filter every 3000-3500 but as Roy mentioned 5000 miles would be fine. I've used Castrol brand oil since the 80s and find it to be a very good oil. Synthetic oil is not needed just be sure to purchase a quality brand.
newer cars go 5000 between changes and synthetic is an option, not a requirement.
