Shouldn't have mattered though. Top-Tier oils are not required by the manufacturer. My sons Kia Rio had oil changed every 5K, like clockwork. Usually off the shelf synthetics, once in a while it got a semi-synthetic (which was factory fill BTW.)
Engine should have been perfectly fine. at 105K, started using oil due to stuck rings. I don't know for sure that Amsoil or anything else would have made any difference. Valvoline R&P maybe? Really no way to prove it as far as I have seen.
A piston soak corrected the issue. Doesn't burn any oil now, but car doesn't get used much anymore.
