What type of oil does a 2015 Chevy Suburban use?
For a 2015 Chevrolet Suburban, use Dexos1 Gen 2 5W-30 motor oil, either synthetic or a synthetic blend. This specification covers the common 5.3-liter V8 and the optional 6.0-liter V8. Always confirm the exact grade on the oil cap or in the owner's manual.
Engine options in the 2015 Suburban
The 2015 Suburban was offered with two gasoline V8 engines. The most common is the 5.3-liter V8 (Vortec 5300), and some trims offered a 6.0-liter V8. Both engines share GM’s Dexos1 Gen 2 oil standard, which is the recommended specification for gasoline GM powertrains in this model year.
Oil specification and grade
The core requirement from GM for the 2015 Suburban is Dexos1 Gen 2 motor oil. In practical terms, that means you should buy a 5W-30 oil that is Dexos1 Gen 2 certified, and you can choose a synthetic-blend or full synthetic formulation. The grade helps ensure wear protection across GM's V8 engines and supports efficient operation across a wide temperature range.
- Dexos1 Gen 2 certification is required by GM for the Suburban's gasoline engines.
- Recommended viscosity is 5W-30 for most driving conditions and climates.
- Both synthetic-blend and full-synthetic Dexos1 Gen 2 5W-30 oils are acceptable.
Choosing Dexos1 Gen 2 ensures compatibility with GM powertrains and protects the warranty when following GM's service guidelines.
Practical notes
Always verify the recommended oil specification with the owner's manual and, if in doubt, ask a GM-certified technician. If your vehicle operates in extreme temperatures or under heavy towing, you may discuss using a higher-performance synthetic oil with your mechanic while staying within Dexos1 Gen 2 compliance.
Summary
In short, a 2015 Chevy Suburban typically uses Dexos1 Gen 2 5W-30 motor oil, suitable in synthetic or synthetic-blend forms, for both the 5.3L and optional 6.0L V8 engines. Verify the exact grade on the oil cap or in the owner’s manual, and follow GM’s recommended oil-change intervals.
