What kind of oil does a 2017 Chevy Trailblazer take?
The typical recommendation for a 2017 Chevrolet TrailBlazer, where the model exists in that year, is 5W-30 Dexos1 Gen 2 full-synthetic motor oil, with about 5 quarts of capacity depending on the exact engine. However, Chevrolet did not offer a US-spec 2017 TrailBlazer, and oil requirements can vary by market and engine. Always verify with your owner's manual or a Chevrolet dealer for the precise specification.
Context: availability and engine options
The 2017 TrailBlazer name has appeared in different markets for different configurations. In the United States, Chevrolet did not sell a 2017 TrailBlazer as a separate model, while other regions may have TrailBlazer variants based on different platforms and engines. Because engine options and emissions requirements vary by market, the exact oil specification can differ. The general rule remains: follow GM’s Dexos1 Gen 2 standard where applicable and confirm the exact spec for your vehicle.
Common oil specifications for 2017 TrailBlazer variants
For many GM gasoline engines from the era, the oil specification centers on Dexos1 Gen 2 with a conventional-to-full-synthetic 5W-30 viscosity. The precise capacity and any engine-specific quirks depend on the engine code and market. The following are representative guidelines you may encounter:
- Viscosity: 5W-30
- Oil type: Dexos1 Gen 2 certified (GM-approved full synthetic or synthetic blend)
- Capacity: typically around 5 quarts, with variations up to about 6 quarts depending on engine and filter
- Quality: full synthetic recommended; synthetic blend acceptable if Dexos1 Gen 2 is maintained
- Change interval: roughly every 5,000–7,500 miles under normal conditions; more frequent under severe or demanding use
To ensure precision, consult your vehicle’s manual or a dealer for the exact oil spec and capacity for your engine code and market, as these details can differ.
How to verify the exact oil for your vehicle
Because oil requirements can vary by engine and region, use these steps to confirm the correct specification for your 2017 TrailBlazer:
- Check the official owner's manual for the exact oil specification and capacity for your engine
- Look on the under-hood oil fill cap or a sticker near the engine bay for Dexos1 Gen 2 mention or GM-approved oil guidance
- Enter your VIN on the Chevrolet/GM service portal or contact a Chevrolet dealership to confirm the correct oil type
- Ask a certified mechanic to identify the correct engine code and corresponding oil specification for your market
Confirming the exact specification helps ensure compatibility with emissions systems and warranty requirements.
Oil change intervals and maintenance tips
With Dexos1 Gen 2 oils, many 2017 GM models support longer intervals under normal conditions, but always follow the official recommendation for your engine. A typical pattern is about 7,500 miles (12,000 km) under normal conditions, with 5,000 miles (8,000 km) or more frequent changes if you drive in severe conditions (extreme temperatures, frequent short trips, towing, or dusty environments). Use a GM/Delco oil filter and ensure a proper oil fill to the correct level after replacement.
Summary
In short, the 2017 Chevy TrailBlazer generally uses Dexos1 Gen 2 5W-30 full-synthetic motor oil, with an approximate capacity around 5 quarts, though exact specs depend on the engine and market. Because the TrailBlazer name appears in multiple regions with different engines, always check the owner’s manual or confirm with a Chevrolet dealer using your VIN to ensure you use the correct oil type, capacity, and change interval.
