What kind of oil does a 2015 Chevy Suburban LTZ take?

The 2015 Chevy Suburban LTZ takes 5W-30 motor oil. This is the recommended oil type and viscosity for this specific model year and trim level of the Suburban SUV.


Detailed Explanation


The 2015 Chevy Suburban LTZ is equipped with a 5.3-liter V8 engine. According to the owner's manual and Chevrolet's recommendations, this engine requires 5W-30 motor oil. The 5W-30 oil specification ensures proper lubrication and protection for the engine under a wide range of operating temperatures.


Using the correct oil type and viscosity is important for the Suburban's engine performance, fuel efficiency, and long-term durability. 5W-30 is a common recommendation for many modern V8 engines, as it provides good cold-weather starting, reduces friction, and maintains viscosity at high operating temperatures.


Oil Change Interval


Chevrolet recommends changing the oil and filter in a 2015 Suburban LTZ every 7,500 miles or 12 months, whichever comes first. However, it's always a good idea to consult your owner's manual or speak with a certified Chevrolet technician to confirm the recommended oil change interval for your specific vehicle.


Oil Capacity



  • The 2015 Chevy Suburban LTZ has an oil capacity of 6 quarts.

  • This includes the oil filter, so the total amount of new oil required during an oil change is 6 quarts.


It's important to use the correct oil type, viscosity, and quantity to ensure the proper operation and longevity of your 2015 Chevy Suburban LTZ's engine.
