How many quarts of oil does a Chevy Trailblazer use?
For most Trailblazers, expect about 4.7 to 5.0 quarts of engine oil with a filter, depending on the engine option.
The Trailblazer has used different powertrains over recent years, most notably two turbocharged inline-three engines in the U.S. market. The exact oil capacity is specified in the owner’s manual and on the under-hood label for your specific model year and engine. The following outlines the typical capacities for the common US-market engines and how to verify yours.
Engine options and their oil capacities
Below are the two most common engines in the US market and their approximate oil capacities (including the oil filter).
- 1.2L turbocharged inline-3 engine — approximately 4.7 quarts (with filter). Recommended oil: Dexos1 Gen 2 synthetic 0W-20.
- 1.3L turbocharged inline-3 engine — approximately 5.0 quarts (with filter). Recommended oil: Dexos1 Gen 2 synthetic 0W-20.
Oil capacity can vary slightly by market, model year, and whether a drain plug adapter is used during service. Always confirm the exact capacity from the owner's manual or the vehicle’s under-hood sticker for your exact configuration.
Maintaining the right oil level
After performing an oil change, fill to the full specification, start the engine, and let it run briefly before rechecking with the dipstick to ensure accurate level. Use the recommended viscosity and a Dexos-approved synthetic oil to protect the engine and meet warranty requirements. Typical oil-change intervals for the Trailblazer are generally 5,000 to 7,500 miles under normal driving, but always follow GM’s guidance for your specific model year.
Summary
The Chevy Trailblazer’s oil capacity depends on the engine. The common 1.2L turbo uses about 4.7 quarts, while the 1.3L turbo uses about 5.0 quarts, both with filters included. Always verify the exact figure in your owner's manual or on the under-hood label and use the recommended Dexos1 Gen 2 0W-20 oil.
