I am the OP and am due for my second and last "free" oil change. If the invoice from my last oil change is accurate, the Toyota dealer did actually use the GTMO branded oil. The service writer also confirmed that was their practice. I hope to pick up another UOA sampling kit and take a sample before the oil is changed again. It will be interesting to see how that performed. I am not expecting any surprises.
