What kind of oil does a 2014 Impala take?
The 2014 Chevrolet Impala requires Dexos1 Gen 2 motor oil, with the exact viscosity depending on the engine you'll have in the car. In short: the 2.5L four-cylinder generally uses 0W-20, while the 3.6L V6 tends to use 5W-30. Always verify with your owner's manual or under-hood oil specification label for your specific vehicle.
Engine options and oil specifications
The 2014 Impala offered two main engines. Oil requirements follow GM’s Dexos1 Gen 2 standard, but the recommended viscosity varies by engine and climate. The information below reflects typical guidance for this model year.
2.5L I4 engine
Two common Dexos1 Gen 2 viscosity options are used for the 2.5L engine. Choose based on climate, driving conditions, and the manual’s guidance.
- Dexos1 Gen 2 0W-20 synthetic motor oil (preferred for fuel economy and cold-start performance)
- Dexos1 Gen 2 5W-30 synthetic motor oil (alternative, suitable for warmer climates or severe service)
Commonly approved oil viscosities for the 2.5L engine in 2014 Impalas:
Concluding: Always confirm with the owner's manual or the information sticker under the hood. 0W-20 is widely used for efficiency, while 5W-30 is a solid alternative when recommended by GM for your region or driving conditions.
3.6L V6 engine
The 3.6L V6 typically calls for a single primary viscosity, with a secondary option only if your manual allows it or you operate in specific climates.
- Dexos1 Gen 2 5W-30 full synthetic motor oil (primary recommendation for most climates)
- Dexos1 Gen 2 0W-30 synthetic motor oil (alternative only if your manual specifies or for extremely cold climates)
Commonly approved oil viscosities for the 3.6L engine in the 2014 Impala:
Concluding: In practice, 5W-30 Dexos1 Gen 2 is the standard recommendation for the 3.6L V6. Always verify with the owner’s manual or dealer guidance to ensure you're using the correct viscosity for your region and driving habits.
Oil change interval and tips
As with most GM models, follow the maintenance schedule in your owner’s manual. Under normal driving, a synthetic Dexos1 Gen 2 oil change interval is commonly around 7,500 miles (12,000 km), while severe driving conditions may require more frequent changes (e.g., 3,000–5,000 miles). Use high-quality synthetic oil from a reputable brand to maintain performance and warranty coverage.
What to check if you’re unsure
If you’re uncertain which engine your Impala has, or you want to confirm the exact oil viscosity, check the following:
- The vehicle’s VIN and the window sticker or owner’s manual for engine specification
- The under-hood oil specification label near the oil fill cap
- GM’s official service information or your nearest Chevrolet dealer
In short, for a 2014 Impala, Dexos1 Gen 2 oil is required, with 0W-20 commonly used for the 2.5L engine and 5W-30 for the 3.6L engine. Verify with the manual or a dealer to confirm the exact viscosity for your car.
Summary
The 2014 Impala uses Dexos1 Gen 2 motor oil. The 2.5L engine typically uses 0W-20, while the 3.6L V6 typically uses 5W-30. Always check the owner’s manual or the under-hood label for the precise specification and follow GM’s recommended oil-change interval for normal versus severe driving conditions. Using the correct Dexos1 Gen 2 oil helps maintain engine performance and warranty compliance.
