I've had good experiences using Supertech in most of my vehicles, except my GMC Acadia. It consumed more than what I was content with, but still within manufacturers tolerances.
My KJ ate a little bit more of it than normal, but the oil that it likes best is Valvoline High Mileage. It did OK on Mobil 1 HM as well, but the Valvoline was smoother (quieter valvetrain) with the least consumption. Although the Mobil 1 HM gives me about .5 higher MPG averaged out over the life of the OCI.
I need to start keeping a log of oil and filter brands and types used in my vehicles; I always meant to and wish I had. I've tried some oils and filters in the past that were great, or not so great, and I can't remember which is which all of the time.
