Best Engine Oil for Chevrolet Traverse 3.6L V6 (310 HP)
The Chevrolet Traverse is a three-row mid-size SUV competing with the Ford Explorer and Toyota Highlander. Its LFY 3.6L V6 produces 310 HP and 266 lb-ft — GM’s ubiquitous high-feature V6 with direct injection, variable valve timing, and cylinder deactivation via Active Fuel Management (AFM). The 3.6L V6 family has been in production since 2004 and powers dozens of GM vehicles, giving it an extensive service record with well-documented strengths and weaknesses. It requires dexos1 Gen 3 certified oil in 5W-30.
Quick Answer: Recommended Oil
For Chevy Traverse 3.6L V6 (310 HP):
- Recommended viscosity: SAE 5W-30
- Oil capacity: 6 quarts with filter
- Required norm: dexos1 Gen 3 / API SP
The LFY 3.6L: Known Issues
Timing chain stretch is the 3.6L’s most significant documented problem. The engine uses three timing chains (one primary, two secondary) that can stretch over time, causing timing codes, rough running, and eventually engine damage. Quality oil maintains the hydraulic chain tensioners — degraded oil with poor pressure characteristics accelerates chain wear. Most chain failures occur between 80,000-120,000 miles.
Oil consumption is documented on some 3.6L V6 engines, particularly with AFM cylinder deactivation active. GM considers up to 1 quart per 2,000 miles “within specification,” though many owners find this excessive. Check the dipstick between changes.
dexos1 Gen 3 is GM’s proprietary petrol oil specification, requiring API SP performance plus GM-specific testing for LSPI prevention, turbocharger deposit control, and timing chain wear. All major oil brands offer dexos1-certified products.

Oil Change Intervals
GM Official: Oil life monitor (typically 7,500-10,000 miles).
Recommended: 5,000-7,500 miles. Timing chain health depends on oil quality — don’t push the oil life monitor to 0%.
Conclusion
The Chevy Traverse 3.6L V6 requires dexos1 Gen 3 certified 5W-30, approximately 6 quarts. Timing chain health is the primary oil-related concern. Change before the oil life monitor demands it.
