Good point. You shouldn't void the Powertrain Warranty, which is often 60k miles, so you have to follow the Owner's Manual oil change and/or OLM for the "new" period. Therefore, you could use the Castrol EP or M1 Annual Protection 20,000 mile OCI from 60k to 80k, yet after that they want you to switch to a High Mileage oil. At least M1 Ext Perf comes in a High Mileage version, 15k at least, so that's the only "EP" oil that makes sense to me these days. (Note M1 Annual Protection does not have a High Mileage version.)
