Best Engine Oil for GMC Canyon 2.7L Turbo (310 HP)
The third-generation GMC Canyon (2023+) is a mid-size truck that replaced the previous V6 and diesel options with a single powertrain: the L3B 2.7L Turbo four-cylinder producing 310 HP and 430 lb-ft. This is GM’s latest turbocharged four-cylinder — a large-displacement single-turbo with direct injection and Active Thermal Management. The L3B also powers the Chevrolet Colorado and is GM’s answer to Ford’s 2.7L EcoBoost V6 in the mid-size truck segment. It requires dexos1 Gen 3 in 0W-20.
Quick Answer: Recommended Oil
For GMC Canyon 2.7L Turbo (310 HP):
- Recommended viscosity: SAE 0W-20
- Oil capacity: 6 quarts with filter
- Required norm: dexos1 Gen 3 / API SP
The L3B: GM’s New Truck Four-Cylinder
The L3B is a 2,687cc inline four-cylinder with an aluminium block, single turbocharger, direct injection, and Active Thermal Management (electric thermostat, split cooling). It produces impressive torque — 430 lb-ft available from 1,500 RPM — making it feel more like a small diesel than a petrol four-cylinder during towing.
Early production concerns have been reported, including turbocharger reliability, transmission calibration issues (rough shifts on the 8-speed auto), and some oil consumption reports. The L3B is a relatively new engine (introduced 2019 in the Silverado, revised for 2023 Canyon) and long-term reliability data is still accumulating.
Towing at 7,700 lbs (properly equipped) is the Canyon’s maximum capacity. The single turbo operates under sustained boost during loaded towing, generating significant oil heat. The 6-quart capacity provides adequate thermal buffering for mid-size truck duty.

Oil Change Intervals
GM Official: Oil life monitor (typically 7,500-10,000 miles).
Recommended: 5,000-7,500 miles. A newer engine with a turbo benefits from conservative intervals while long-term reliability data accumulates.
Conclusion
The GMC Canyon 2.7L Turbo requires dexos1 Gen 3 0W-20, 6 quarts. GM’s latest truck turbo-four delivers diesel-like torque from a petrol engine. Conservative intervals protect the turbo and support long-term reliability.
