I'm getting dummer about oil but I'm trying to learn. I have a 2016 Malibu with a 2 litre turbo. I understand it requires 5w30 SN graded oil. Also it requires GF5 oil. The oil I have is SN rated which is Castrol and Mobil and is also Dexos approved. I want the best oil possible so my question is should I buy the new super synthetic oil and please tell me why or why not.
Thank you,
Fred
