The 2019 Chevrolet Colorado with the 3.6-liter V6 engine requires 6 quarts of engine oil, about 5.7 liters, when performing a standard oil change with the filter. Use Dexos1 Gen 2 5W-30 synthetic oil unless your owner's manual specifies a different grade.
Beyond the simple number, this question covers oil capacity with or without the filter, the recommended oil specification, and practical maintenance notes for keeping the 3.6 L V6 running smoothly in a midsize pickup.
Oil capacity and filter inclusion
The official oil capacity for the 2019 Colorado with the 3.6 L V6 is 6 quarts (5.7 liters) when the oil filter is replaced. If you perform an oil drain without changing the filter, you’ll use slightly less—about 5 quarts. Replacing the filter during every oil change is essential for proper filtration and oil pressure.
Notes on capacity variations
Capacities can vary slightly depending on the exact engine variant, drain procedures, or filter size. Always verify the specification in the owner’s manual or on the under-hood information label for your exact configuration.
Recommended oil and grade
GM generally requires Dexos1 Gen 2-certified synthetic oil for this engine. The typical viscosity recommended for everyday driving is 5W-30. In some climates or depending on the exact manual, other grades may be allowable, so it’s important to confirm the specification in the owner’s manual or on the vehicle’s information label.
Why oil grade matters
Using the correct viscosity and Dexos1 Gen 2 certification helps ensure proper lubrication, protective wear, and engine longevity across temperature ranges.
Maintenance and change interval tips
Oil-change intervals for this vehicle commonly align with GM guidelines and the oil-life monitor, often around 7,500 miles for standard Dexos1 Gen 2 synthetic oil, though exact intervals can vary by driving conditions and use. Always use a quality oil filter and torque the drain plug to the manufacturer’s specification.
Summary
For a 2019 Chevy Colorado with a 3.6 L V6, plan on about 6 quarts of engine oil with the filter, using Dexos1 Gen 2 5W-30 synthetic oil unless your manual indicates otherwise. Confirm the exact specification with your owner's manual or dealership service data, and follow the recommended change intervals to maintain optimal engine performance.
