Supertech high milage is the only one I’ve found that doesn’t burn like crazyStop using Supertech, I noticed excessive oil burning with that oil, tried it once, never again in a Kia.
Switched back to Pennzoil and it's almost nothing.

At her next OCI, I’m doing another piston soak, cylinder 3 seems to be the main culprit for our burning issues. After that, I’m going to run some Valvoline restore and protect. I’ve been down the whole EC30 thing. Nothing made a difference except for the piston soak with the ACDelco top engine cleaner.
