Wife's car, 2015 Chevy Impala 3.6L Direct Injection V6 spec'd for D1G1.
Out of warranty with over 120,000 miles.
120 miles a day round trip 5 days a week to and from work, plus weekends to ball games and/or shopping, usually minimum 120 miles round trip.
95% highway miles 70-75 mph.
9000-9500 usual oci's per OLM.
I have several jugs of CJ rated T5 Rotella 10/30 in my stash for my old 82 GMC pickup.
Would you run an OCI or 2 in this car with this oil?
