My buddys girlfriends car( 2013 Kia Forte, 2.0 4 cylinder, 20kmiles), i just changed her oil using Autozone 5W30 synthetic dexos and a napa gold, he wants to leave it in for 7k. She does trips of at least 15 miles one way every day, but it will probably take her a good 6 months to put 7k miles. Do yall think this house brand is up to the task for 7k without a UOA?
