What kind of oil goes in a Chevy Blazer?
Most modern Chevy Blazer models require synthetic motor oil that meets Dexos1 Gen 2 specifications, typically 5W-30 for the 2.0L turbo engine, with the 3.6L V6 using 0W-20 or 5W-30 depending on year and climate. Always check the vehicle’s owner’s manual or the oil fill cap for the exact viscosity and Dexos requirement.
Beyond the general rule, the right oil depends on the engine, model year, and local driving conditions. This article breaks down the two main gasoline engines used in current Blazers and explains the correct oil type, capacity, and maintenance intervals to keep your SUV performing at its best.
Engine options and oil specifications
The following guide highlights the two common Blazer gasoline engines and the oil they typically require. Always verify on your vehicle’s label or manual.
2.0L Turbo I4 (LTG) — Dexos1 Gen 2 synthetic oil, typically SAE 5W-30. Oil capacity with filter is about 5 quarts.
3.6L V6 (LGX) — Dexos1 Gen 2; viscosity commonly 0W-20 or 5W-30 depending on model year and climate. Check the owner’s manual for the exact specification.
Dexos1 Gen 2 compatibility ensures the oil works with GM’s engine design and future diagnostics. If you’re unsure, a Chevrolet service advisor can confirm the exact Dexos spec for your year and engine.
Dexos1 Gen 2 compatibility
Dexos1 Gen 2 is GM’s current standard for many gasoline engines, including the Blazer. Using an oil that meets this specification helps with engine protection, friction reduction, and warranty coverage. Always verify the exact specification for your year and trim level.
Oil capacity and change intervals
The capacity and maintenance intervals depend on engine type and driving conditions. Use the following as a general guide, then tailor to your vehicle’s specifications.
:
- 2.0L Turbo I4: about 5 quarts with filter
- 3.6L V6: around 5.5–6 quarts with filter, depending on exact configuration
: Dexos1 Gen 2 synthetic oil; for most Blazers this is 5W-30 for the 2.0L turbo and typically 0W-20 or 5W-30 for the 3.6L V6 depending on model year. :
- Normal driving: about every 7,500 miles or 12 months with synthetic oil
- Severe service (towing, frequent short trips, extreme temperatures): every 3,000–5,000 miles or 3–6 months
Always verify on the vehicle’s information label in the engine bay or in the owner’s manual, as GM’s recommendations can vary by year and market. When in doubt, ask a dealership or a qualified mechanic to confirm Dexos1 Gen 2 compatibility and the right viscosity for your climate and driving style.
How to check and maintain oil correctly
Regular checks and following the correct change schedule help protect the engine. Use the dipstick to verify oil level and color between changes, and replace the oil filter with every oil change. Use a high-quality synthetic oil that meets Dexos1 Gen 2 specifications.
For maximum accuracy, consult your Blazer’s exact year and engine details to pull the latest GM maintenance schedule and ensure the right viscosity and Dexos specification are used for your climate and usage patterns.
Summary
In short, the Chevy Blazer generally uses Dexos1 Gen 2 synthetic oil, with 5W-30 commonly recommended for the 2.0L turbo engine and either 0W-20 or 5W-30 for the 3.6L V6 depending on year and climate. Always confirm the precise specification in your owner’s manual or on the under-hood label, and follow the recommended oil change intervals to keep your Blazer running smoothly in everyday driving and tougher conditions.
