I totally agree with an early change. Real data to show that has positive benefits down the road (longevity).
I use the M1 10w30 HM in several (basically all) cars - out to 7,500. NA, turbo, and Turbo GDI. Have done UOA to test it and it's been fine, including in the turbo GDI.
Can you share that data?
I used to do the same thing and was surprised when Honda gave specific instruction NOT to change early as apparently they have for decades.
They want the factory fill to stay in the entire normal OCI as it contained lots of moly from the assembly lube.
Curious what the kia manual calls for?
