is 5w30. If used in extreme cold of -25 C then a 0w30 can be
used. I would not be using a 0/5w20 oil.
I do this for a living. Spec is 0/5w20
#13-00-90-002: Information for Vehicles Factory Filled With dexos1 5W-20 Oil Are Approved to Substitute dexos1 0W-20 Oil as Optional Top Off and Service Fill - (Dec 13, 2013)
2013-2014 Cadillac ATS
2013-2014 Chevrolet Malibu
2013-2014 Chevrolet Spark
2014 Chevrolet Impala
Vehicles Equipped With Engine RPO LCV, LKW or LLO
The above listed Model Year vehicles, equipped with the specified engine RPO codes were factory filled with dexos1™ 5W-20 oil and the engines were fitted with engine oil fill caps that say: SAE 5W-20 dexos. GM Powertrain has tested, validated and approved the use of 0W-20 dexos1™ as an acceptable substitute and optional top off and service fill for these vehicles.
My 2014 GMC Terrain with the 2.4 (LEA) is still 5w30. So the 1.2 and the new 2.5 ecotec
has 0/5w20 recommended. You stated that you do this for a living, are you a GM Tech ?
