This is my wife's Acura RDX with a stock Turbo on a 2.3 liter four cylinder VTEC engine. I did this UOA to see how conservative the Oil Life Monitor was on this engine. This car is driven with a mix of city/highway, and short & long distance trips.
Honda requires oils that meet HTO-06 specification for this engine. AFAIK, only M1, PP & SSO meet these requirements. It looks like even with the Turbo, the OLM is conservative:
