"The universal averages for this engine are specific to hybrids, but not necessarily all plug in hybrids. There are 279 samples in the file currently; many are from the C-Max Energi and Fusion Energi, and there are also some traditional hybrid MKZs in the file, as well as C-Max and Fusion models that may be traditional hybrids. Not all of our customers specify whether they have a standard hybrid verses the plug in version. As more of these engines come onto the market and oil data pool increases, we'll know more about what's normal for these vehicles, but no matter the circumstances, it's hard to be concerned with every single wear metal in the single digits like we found in your sample. Even if the combustion engine was running for a fraction of the miles you provided on the oil, these would still be fantastic results."
