For your 2008 GMC Sierra, it is advised to use SAE 5W-30 oil. If you reside in a colder area where the temperature drops below 20°F, it would be better to opt for SAE 0W-30. Your dealer suggests using GM certified oil to avoid voiding the warranty on your Sierra. Be cautious when selecting your oil from the store, making sure it's certified. You can also seek assistance from a store employee if needed. Engine oil functions to lubricate and clean the engine. It is recommended to regularly check your oil to prevent strain on your motor while driving.

The 2008 GMC Sierra needs oil that meets GM Standard GM6094M, with SAE 5W-30 being the top choice. In very cold climates, below 20°F (29°C), it's best to use SAE 5W-30 synthetic oil or SAE 0W-30 oil for improved cold starting and enhanced engine protection.
