BRANDON: We saw the last comment mentioned two HPDE on this oil. This oil saw three HPDE's, so we're quite pleased to see that metals haven't really increased much. And this oil saw a longer overall run too, so clearly the extra miles and the hard use isn't giving this engine any hassle. The viscosity read in the expected range for 5W/40, and there was no measurable fuel, water, coolant, or excessive dirt present in this sample. All things considered, this engine appears to be in great shape as of the 6/11/12 sample date. Nice report.Myth: You should change your oil after every track day.
