I'm overboard. I have a 25 Sorento Prestige SX Hybrid. I change it at 500 miles and switched to 5w 30. Then at 2k, and every 3k after that. I also add 5 extra pounds of air in my tires. And installed a washable K&N air filter. Last 100 mile round trip.... 35.3 MPG Whatever the manual says. Cut in half or more. I have the luxery of doing my own service.My 2022 Sorento just reached 1000 miles on the odometer. Is that the time for its first oil change?
