The 2003 GMC Envoy requires SAE 5W-30 oil. GMC advises using synthetic oil for oil changes. Nowadays, there are two common types of oil: conventional and synthetic. Conventional oil is traditional, made from petroleum, while synthetic oil is more advanced, created in a lab for improved protection and longer lifespan. With synthetic oil, you only need to change it every 7,500 miles, compared to 3,500 to 5,000 miles with conventional oil. I suggest checking your oil at least once a month to ensure it is at the proper level and in good condition.

I am curious about which oil brand to use, rather than the specific type.

I own a GMC Envoy and I'm wondering whether I should use 10W40 or 5W30 oil for my car with 200,000 miles.
