In most modern Equinox models, you should use Dexos1 Gen 2 certified motor oil with the viscosity specified for your engine and climate, typically 0W-20 or 5W-30. Always confirm the exact requirement in your owner's manual or on the under-hood label.
Dexos1 Gen 2 and viscosity basics
GM requires Dexos1 Gen 2 oil for most Equinox models built from the early 2010s onward. The exact viscosity depends on the engine and operating environment, with 0W-20 and 5W-30 being common options. Using oil that does not meet Dexos1 Gen 2 can affect lubrication performance and may impact warranty claims.
Why this matters for your engine
Using the correct Dexos1 Gen 2 specification ensures compatibility with the engine’s tolerances, fuel efficiency targets, and emissions systems. It also supports recommended drain intervals for synthetic or synthetic-blend oils.
Note: these are general guidelines. Your exact requirement is printed on the oil fill cap, the under-hood sticker, or in the owner’s manual.
- Dexos1 Gen 2 approval: The oil should explicitly state Dexos1 Gen 2 on the label.
- Viscosity options: Common choices are 0W-20 and 5W-30; the exact grade depends on your engine and climate—verify in the manual or label.
- Oil type: Synthetic or synthetic-blend oils are typically recommended for newer Equinox engines, though some older models can use conventional oil if needed.
Before buying oil, look for two key details on the bottle: Dexos1 Gen 2 approval and the correct viscosity for your vehicle.
In summary, ensure the oil is Dexos1 Gen 2 certified and matches the viscosity specified for your vehicle.
How to determine the exact oil for your Equinox
To be certain you select the right oil, follow these steps and verify with authoritative sources when in doubt.
- Identify your Equinox’s model year and engine code, since requirements evolved across generations.
- Check the owner’s manual section on Engine Oil for the exact grade (for example, 0W-20 or 5W-30) and the Dexos specification.
- Inspect the oil fill cap and any under-hood labels for stated viscosity or specs alongside Dexos requirements.
- Choose an oil that is Dexos1 Gen 2 certified; decide between synthetic, synthetic-blend, or conventional based on driving conditions and budget.
- Follow GM’s recommended oil-change intervals for your oil type and driving conditions, and use a high-quality oil filter.
If you are still uncertain after these checks, consult a GM-certified technician or your local dealership to confirm the correct product for your exact Equinox.
Summary
The bottom line is to use Dexos1 Gen 2 certified oil in the viscosity specified for your model’s engine and climate (commonly 0W-20 or 5W-30). Always verify with the owner’s manual or engine label, and choose synthetic or synthetic-blend oil as recommended. Adhering to the correct specification helps protect the engine, maintain efficiency, and uphold warranty terms.
