Choose Chevy Trax Engine Oil Type
The short answer
The right oil for a Chevrolet Trax depends on which generation and engine you have. In the North American market, the first-generation Trax (2015 to 2022 model years) with the 1.4-liter turbocharged four-cylinder is generally specified for SAE 5W-30 oil that meets GM's dexos1 standard. The second-generation Trax (2024 model year onward) with the 1.2-liter turbocharged three-cylinder is generally specified for SAE 0W-20 oil that meets dexos1. Treat both as the commonly published specifications, not a substitute for your own vehicle's documentation. The owner's manual and the marking on the oil filler cap are the authoritative sources, and you should check them before buying oil.
Two terms appear in every Trax oil recommendation. SAE viscosity, such as 5W-30 or 0W-20, describes how easily the oil flows. The number before the W reflects cold-temperature flow, and the second number reflects thickness at operating temperature. Dexos1 is GM's own licensing standard for gasoline engine oil. Oils that pass GM's requirements carry the dexos1 trademark on the container.
Oil specification by Trax generation
Generation | Model years (North America) | Engine | Commonly specified viscosity | GM specification; First generation | 2015–2022 | 1.4L turbo four-cylinder | SAE 5W-30 | dexos1; Second generation | 2024 onward | 1.2L turbo three-cylinder | SAE 0W-20 | dexos1 (current generation)
The table does not cover every market. Outside North America, the Trax and closely related models have been sold with other engines, including a 1.8-liter gasoline engine and diesel engines in some regions. Those engines can carry different viscosity and specification requirements. Owners of vehicles sold outside the United States and Canada should rely on the regional owner's manual.
Why the dexos generation matters for turbocharged engines
Both Trax generations use small turbocharged engines. Engines of this type can be susceptible to low-speed pre-ignition (LSPI), which is an abnormal combustion event that can damage the engine. GM updated its standard to dexos1 Gen 2, partly to address LSPI. The current version, dexos1 Gen 3, followed in the early 2020s. GM describes the newer generations as backward compatible. An oil licensed to the current dexos1 generation is therefore generally appropriate for older Trax models that call for dexos1, provided the viscosity matches what the manual specifies.
Choosing between oil options
Most shoppers are choosing among brands and product lines, not among specifications. Once you know the required viscosity and that the oil must meet dexos1, use the criteria below to narrow the shelf.
Dexos1 licensing: A dexos1-licensed oil in the correct viscosity is the option aligned with GM's requirements. An oil without the dexos1 mark may still meet general industry standards, but it has not been confirmed against GM's specification. Viscosity match: Use the grade printed in your manual or on the filler cap, such as 5W-30 for the first-generation 1.4L or 0W-20 for the second-generation 1.2L. Do not substitute a different grade unless the manual allows it. Synthetic versus blend: Many dexos1-licensed oils are full synthetic or synthetic blends. What matters for compliance is the dexos1 license, not the word synthetic on the label. Full synthetic is an editorial preference for owners who want extra margin in extreme heat, extreme cold or frequent short trips. It is not a documented Trax requirement. Warranty considerations: Using oil that meets the specified standard is the safer choice for vehicles under warranty. Keep receipts that show the oil grade and specification used at each change.
Oil capacity and change intervals
This guide does not state a verified oil capacity for either Trax engine. The figure in your owner's manual is the one to follow, and you should confirm the level on the dipstick after filling. Trax models use GM's Oil Life Monitor, which estimates when the oil needs changing based on operating conditions, not a fixed mileage. Follow the monitor's prompt and any maximum interval listed in the manual, whichever comes first.
What to do next
Confirm your Trax's model year and engine. Then check the owner's manual or the oil filler cap for the viscosity. Buy an oil in that grade that displays the dexos1 trademark. If your vehicle was sold outside North America or has a 2023 model-year build date, check the manual directly. This guide does not document specifications for those cases.
