The 2014 Chevrolet Impala with the 3.6-liter V6 uses Dexos1 Gen2 certified 5W-30 full-synthetic motor oil, and it holds about 6 quarts (roughly 5.7 liters) with the filter installed.
This matters because the Impala’s V6 (the 3.6L engine commonly coded as LFX) requires a specific GM-approved oil specification to maintain performance and warranty coverage. Using the wrong oil grade or non-Dexos oil can affect engine wear, emissions performance, and service intervals. The details below lay out the key specification and service guidance.
Oil specification and service guidelines
Key details for quick reference:
- Oil type and specification: Dexos1 Gen2 certified 5W-30 full-synthetic motor oil.
- Oil capacity: About 6 quarts (5.7 liters) with the filter.
- Recommended change interval: Typically every 7,500 miles (12,000 km) or 12 months, whichever comes first, when using synthetic oil. Severe driving conditions may warrant shorter intervals.
- Oil filter: Use an OEM or equivalent high-quality filter designed for the Dexos1 Gen2 oil and 3.6L V6.
- General caution: Confirm the exact specification in the owner's manual or with a Chevrolet dealer; stay within GM-approved Dexos1 Gen2 guidelines.
Sticking to these specifications helps preserve engine performance, fuel economy, and warranty compliance.
Practical shopping and maintenance tips
