Complete Oil Specifications
Your 2023 GMC Canyon (Gen 3) with the 2.7T L3B engine requires 0W-20 full synthetic oil meeting GM dexos1 Gen3 and API SP / ILSAC GF-6A. The L3B is GM’s turbocharged 2.7L four-cylinder, producing up to 310 horsepower and 430 lb-ft of torque in the AT4X trim — remarkable output from a four-cylinder truck engine.

Why dexos1 Gen3 0W-20 for the High-Output L3B
The L3B’s high specific output (over 115 hp/L) comes from aggressive turbo boost pressure and direct injection operating in a relatively small displacement. Under towing or off-road loads, the turbocharger operates near its thermal limits. dexos1 Gen3’s enhanced oxidation resistance protects the turbo bearings through sustained high-load cycles, while the 0W-20 viscosity ensures rapid cold-start oil delivery to the turbo shaft before operating temperature is reached. This is especially important for truck use, where the engine may go from cold start to full towing load within minutes.
Using incorrect oil will:
- ❌ Accelerate turbo bearing wear under towing/hauling loads with insufficient film strength
- ❌ Increase LSPI risk from the L3B’s high-boost direct injection system
- ❌ Void GM powertrain warranty (dexos1 approval required for all GM turbocharged engines)

Severe Service Check
Use the 3750-mile interval if you:
- Tow regularly near the rated capacity (7,700 lbs for Canyon)
- Haul heavy payloads in the truck bed
- Drive off-road on trails, in mud, or at steep grades
- Operate in extreme temperatures — desert heat or sustained sub-zero cold
Installation Details
Drain Plug Torque: 19 ft-lbs
The 2023 Canyon Gen 3 uses a standard metal drain plug. Verify your specific configuration — some earlier Canyon models had plastic composite pans with different requirements.
OEM Filter: AC Delco PF64

Pro Tip: The L3B holds 6.0 quarts — significantly more than the previous Canyon’s 2.5L engine. Have a full 6-quart jug on hand rather than trying to piece together partial quarts.
FAQs
What oil does a 2023 GMC Canyon 2.7T take?
0W-20 full synthetic with GM dexos1 Gen3 approval.
How many quarts does the Canyon 2.7T need?
6.0 quarts with a new filter, 5.7 without.
Is this the same oil as the Chevy Colorado 2.7T?
Yes. The 2023 Colorado and Canyon share the L3B engine and use identical oil specifications — 0W-20 dexos1 Gen3.
What is dexos1 Gen3 and why does it matter?
dexos1 Gen3 is GM’s latest oil specification (mandatory for 2022+ turbocharged models). It improves on Gen2 with better LSPI protection and fuel dilution resistance — both critical for direct-injection turbo truck engines under towing loads.
How often should I change the oil?
Every 7500 miles maximum for normal driving. Use 3750 miles for towing, off-road, or severe conditions.
