I have a 2022 Kia Stinger, turbocharged. It takes 0w-20, and I usually use Mobil 1, but Supertech is $12 less for 5 quarts. The certification matches what the owners manual asks for. Any issue at all using the Supertech oil in place of Mobil 1? I change my oil every 6k miles.
I do kind of feel like a cheap ass for wanting to save $12, but wondering if there is any real difference between the M1 and Supertech if I consistently change the oil?
