A 2015 Chevrolet Equinox uses Dexos1 Gen 2 certified engine oil, with 5W-30 being the common factory fill for most configurations.
The 2015 Equinox offered two engines—the 2.4-liter inline-four and the 3.6-liter V6. Both engines require Dexos1 Gen 2 oil and typically call for a 5W-30 viscosity, though you should verify the exact grade in your owner's manual or on the under-hood label for your climate and engine variant.
Oil specification by engine
Two engine options were available in 2015, and both share the Dexos1 Gen 2 requirement. Here’s how the oil recommendation generally aligns with each engine.
- 2.4L four-cylinder — Dexos1 Gen 2 oil, typically 5W-30; use a GM-approved Dexos1 Gen 2 lubricant. Check the owner’s manual or the label under the hood for any climate-specific adjustments.
- 3.6L V6 — Dexos1 Gen 2 oil, typically 5W-30; follow the same Dexos1 Gen 2 requirement and viscosity guidance as the 2.4L.
In all cases, ensure the oil you use is Dexos1 Gen 2 certified and adhere to the viscosity recommended in your manual. Do not substitute non-Dexos1 Gen 2 oils if your engine requires Dexos1 Gen 2.
Summary
Bottom line: For the 2015 Equinox, use Dexos1 Gen 2 engine oil with a typical viscosity of 5W-30 for both available engines. Always confirm the exact specification for your vehicle in the owner's manual or on the under-hood label, and use only Dexos1 Gen 2 oils to maintain performance and warranty coverage.
