In brief, the answer depends on which engine your Colorado uses: gasoline engines use Dexos1 Gen 2 motor oil, while the Duramax diesel uses Dexos2. The correct viscosity varies by engine and climate, so always verify in your owner’s manual or on the engine’s under-hood sticker.
Engine options and oil specifications (2019 Colorado)
The 2019 Colorado offered three powertrains: 2.5L inline-4, 3.6L V6, and the 2.8L Duramax turbodiesel. Each has its own oil standard and recommended viscosity. Use the official manual for the exact figure, as regional updates can change requirements.
Gasoline engines in this model family typically require Dexos1 Gen 2 oil. Viscosities commonly listed by market include 0W-20 as the preferred choice, with 5W-30 acceptable if 0W-20 is not specified by your owner's manual.
- Dexos1 Gen 2 certified motor oil for gasoline engines
- Typical viscosities: 0W-20 preferred; 5W-30 acceptable as an alternative per manual
The Duramax 2.8L turbodiesel requires Dexos2 oil, usually a full-synthetic 5W-40. In some climates, 0W-40 may be allowed per GM guidance. Diesel engines have different friction and emissions-control needs, so using the correct Dexos specification is essential.
- Dexos2-certified oil for diesel engines
- Common viscosity: 5W-40; 0W-40 may be allowed in certain regions per GM guidance
Note: Oils must meet Dexos1 Gen 2 (gasoline) or Dexos2 (diesel) standards, and viscosity should align with the guidance in your manual and under-hood sticker.
How to confirm the exact specification for your vehicle
To ensure you are using the precise oil specification for your Colorado, follow these steps:
- Locate the owner’s manual or the official GM online specification for your exact model and market.
- Check the under-hood oil specification label near the engine for the recommended Dexos standard and viscosity.
- When in doubt, contact an authorized Chevrolet dealer or GM customer service for confirmation, especially if your Colorado has a different regional specification.
Adhering to the correct specification helps maintain performance, emissions compliance, and warranty coverage.
Summary
The 2019 Chevy Colorado’s oil depends on the engine: gasoline models use Dexos1 Gen 2 oil with a typical viscosity around 0W-20 (or 5W-30 where 0W-20 isn’t specified), while the Duramax diesel uses Dexos2 oil, most commonly 5W-40. Always verify the exact requirements in the owner’s manual or on the engine placard and follow the recommended oil-change intervals to keep the pickup running smoothly.
How many quarts of oil does a 2019 Chevy Colorado 3.6 L take?
6 quarts
Capacity: 6 quarts (with filter). After refill check oil level.
Is Colorado comfortable for long trips?
The interior of the Chevy Colorado is where functionality meets modern comfort, making it more than just a rugged workhorse. Whether you're using it for daily commuting, long road trips, or off-road adventures, Chevrolet has designed the cabin to provide comfort, connectivity, and convenience.
Can I use 5W-30 instead of 0W-20 in Silverado?
Yes, you can use Dexos1 Gen 2 or Gen 3 5W-30 in your 2025 Silverado engine while you're in a specific location, especially if 0W-20 is unavailable. It is recommended to use 0W-20 for fuel economy (CAFE standards), but the 5.3L Gen V V8 engine is mechanically capable of running 5W-30, particularly in hot climates.
What type of oil do I need for a 2019 Chevy Colorado?
The Proper Chevy Colorado Oil Type
As we mentioned earlier, late-model Colorado vehicles use 5W-30 synthetic oil. Earlier models might recommend 0W-30 synthetic oil. You might also see this oil recommended if you enjoy off-roading or use your truck for certain other specialized purposes.
