Dexos1 Gen 1 certified 5W-30 engine oil is recommended for the 2010 Equinox.
In 2010, the Chevrolet Equinox offered two engines—the 2.4-liter four-cylinder and the 3.0-liter V6. For both powertrains, GM’s guidance is to use a Dexos1-certified 5W-30 engine oil, with either synthetic blend or full synthetic formulations. This specification helps ensure proper lubrication, performance, and warranty protection.
Oil specifications by engine
The following guidelines apply to both engines in the 2010 Equinox; the key requirements are Dexos1 certification and a 5W-30 viscosity range.
- 2.4L four-cylinder engine: Dexos1 Gen 1 certified 5W-30 engine oil (synthetic blend or full synthetic).
- 3.0L V6 engine: Dexos1 Gen 1 certified 5W-30 engine oil (synthetic blend or full synthetic).
Note: Always consult the owner's manual or a Chevrolet service professional to confirm the exact oil specification for your specific vehicle, and use an oil that carries the Dexos1 certification to maintain warranty coverage and engine protection.
Additional notes
Oil capacity and change intervals vary by engine and driving conditions. As a general guideline, many GM vehicles from this era use a 5W-30 capacity in the neighborhood of about 5 quarts for the 2.4L and around 6 quarts for the 3.0L, with oil changes typically recommended every 5,000–7,500 miles when using conventional oil and longer intervals with synthetic oil. Always verify using the dipstick and the service schedule in your manual.
Summary
For a 2010 Equinox, the correct oil type is Dexos1 Gen 1 certified 5W-30, usable in both the 2.4L I4 and the 3.0L V6, with either synthetic blend or full synthetic formulations. Follow the manual for exact capacity and maintenance intervals, and choose a reputable brand to ensure optimal engine protection and warranty compliance.
