In most cases, the 2018 Chevy Equinox requires Dexos1 Gen 2 synthetic motor oil with a viscosity of 0W-20.
The 2018 Equinox introduced a newer generation with multiple engine options, and Chevrolet specifies using Dexos1 Gen 2 oil that matches the engine and climate. While 0W-20 is the standard for many configurations, some engines or markets may specify 5W-30. Always verify the exact requirement for your vehicle in the owner's manual or on the oil filler cap.
Oil specification by engine
Here are typical oil recommendations by engine type for the 2018 Equinox. Note that exact viscosity and Dexos specification can vary by market and model year; always consult the manual or the cap under the hood for your VIN.
- 1.5L turbocharged engine: Dexos1 Gen 2 approved oil, commonly 0W-20 synthetic.
- 2.0L turbocharged engine: Dexos1 Gen 2 approved oil, commonly 5W-30 synthetic.
- 1.6L diesel engine (where offered): Dexos2 approved oil, commonly 5W-40 synthetic.

How to verify the exact specification for your vehicle
Use these steps to confirm the correct oil type and viscosity for your 2018 Equinox:
- Check the owner's manual oil specification section for Dexos1 Gen 2 and the recommended viscosity.

Following the exact specification ensures proper lubrication, performance, and warranty compliance.
