ive used ultra ever since my first oil change. except for my last oil change, had to use the new platinum pureplus instead. waiting for walmarts around me to stock the ultra platinum still
anyway, looking at the technical stats between the old ultra and the new ultra platinum, it should be just as good as the old ultra. the cSt viscosity is the same and the only thing that concerns me is the NOACK volatility went up from 6% to 10%.
anyway, ive done multiple UOA's with regular ultra, even after track days with oil temps at ~240-250F and that oil held up like a champ. never sheared below a proper 30 weight and had plenty of additives left over even at 5K OCI's. cant wait to get a proper one for ultra platinum
