The 2016 requires 0W-20 synthetic. The correct oil is more important now than ever with the tight tolerances, two stage oil pumps and high flow lubrication requirements of today’s modern GM engines.
Beginning in 2012, oil pumps began to regulate main gallery feedback instead of pump output pressure, which means that the oil pump does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.
