The 2013 Cadillac ATS generally uses Dexos1 Gen 2 certified synthetic engine oil in 5W-30 as the standard specification across its engine options.
The ATS lineup for 2013 included three engines: a 2.5L I-4, a 2.0L turbocharged I-4, and a 3.6L V6. Across these variants, GM typically requires Dexos1 Gen 2 5W-30 synthetic oil to meet lubrication, emissions, and warranty requirements. Always confirm the exact specification for your build with the owner’s manual or a GM technician, especially if you operate in extreme climates or have unusual driving conditions.
Engine options and oil requirements
Here is a quick overview of the engine options available in the 2013 ATS and the oil specification they typically use.
- 2.5L I-4: Dexos1 Gen 2 certified synthetic oil, viscosity 5W-30.
- 2.0L turbocharged I-4: Dexos1 Gen 2 certified synthetic oil, viscosity 5W-30.
- 3.6L V6: Dexos1 Gen 2 certified synthetic oil, viscosity 5W-30.
Whichever engine your car has, the standard requirement is Dexos1 Gen 2 5W-30 synthetic oil. If you are unsure, check the oil container for Dexos1 Gen 2 certification and consult the owner’s manual to confirm the correct viscosity for your climate and mileage.
Shopping tips and maintenance considerations
Before you buy oil, keep these guidelines in mind to ensure you meet GM’s specifications.
- Look for Dexos1 Gen 2 certification on the oil container. This ensures the oil meets GM’s lubricant requirements for newer gasoline engines.
- Use 5W-30 viscosity (typical for most climates and miles on a 2013 ATS). In extremely hot or cold climates, defer to the manual for any climate-specific viscosity notes.
- Prefer synthetic or synthetic-blend oils that are Dexos1 Gen 2 compliant to maximize protection and drain intervals.
Concluding note: Using the correct Dexos1 Gen 2 5W-30 synthetic oil helps maintain engine performance and supports your warranty, so verify the exact specification for your vehicle’s engine and climate before purchasing.
Summary
The 2013 Cadillac ATS generally requires Dexos1 Gen 2 certified synthetic engine oil with a viscosity of 5W-30. This applies across the 2.5L I-4, 2.0L turbo, and 3.6L V6 engines. Always double-check the owner's manual or GM's lubricant guide when shopping for oil to ensure compatibility, especially if you live in areas with extreme temperatures or have long-drain intervals.
