What type of gas does a Chevy Blazer take?
The Chevy Blazer generally runs on regular unleaded gasoline with an octane rating of 87 or higher, and premium fuel is not required for standard operation.
For certainty across different model years and engines, always check the specific owner’s manual or the fuel-filler door label for your vehicle. Some trims or regions may have slight variations, but 87-octane regular is the baseline guidance for most Blazer models.
Fuel Type and Octane Requirements
Below is a quick guide to the typical fuel expectations for recent Blazer models.
- Regular unleaded gasoline with an octane rating of 87 (minimum) is the standard specification for most Chevy Blazer engines.
- Higher-octane fuels (89–93 octane) can be used if you prefer, or if your manual notes they are recommended for certain driving conditions, but they are not required for normal operation.
- Do not rely on E85 or other ethanol blends unless your specific Blazer version is confirmed by the manual as compatible; most models are not flex-fuel vehicles by default.
In practice, most drivers will obtain similar performance and efficiency using 87-octane regular gasoline. Only consult your owner’s manual or a dealer for any model-specific caveats or updates.
Engine Variants and Octane Considerations
The Blazer comes with multiple engine options over its generations, but the official recommendation remains regular unleaded gasoline (87 octane) as the baseline. Some owners note that higher-octane fuel may offer marginal benefits in certain high-load situations, but it is not a mandated requirement for normal driving. Always verify with your vehicle’s documentation for your exact year and trim.
If you ever have questions about the correct fuel for your Blazer, your local Chevrolet dealer can provide the most accurate guidance for your particular vehicle and market.
Summary
Bottom line: a Chevy Blazer typically takes regular unleaded gasoline at 87 octane or higher, with premium fuel not required for standard operation. Always confirm with the owner's manual or door placard for your specific model and year, and seek dealer guidance if in doubt.
