The 2014 Chevrolet Impala with a 3.6 L V6 typically requires about 6 quarts of engine oil when you perform an oil change with a new filter (roughly 5.7 liters). Without changing the filter, you’ll use around 5 quarts. Always verify the level with the dipstick after refilling.
Understanding the oil capacity for this specific engine comes down to whether you replace the oil filter during a change and the precision of your measurements. The 3.6 L V6 used in the 2014 Impala shares this general capacity pattern with other GM 3.6 L engines, but exact numbers can vary slightly by filter size and production variations. The guidance below reflects typical factory specifications and best practices as of the vehicle’s model year, and you should always confirm with your owner's manual or a trusted GM service bulletin if you’re unsure.
Oil capacity and what to expect
Standard figures you should rely on when planning an oil change are listed below.
- With a new oil filter: 6 quarts (approximately 5.7 liters).
- Without a new oil filter (just the oil): about 5 quarts (approximately 4.7 liters).
These amounts provide a practical range for a full oil change. Always fill gradually and recheck the level with the dipstick to bring it to the proper full range.
Oil type and maintenance guidelines
Beyond capacity, using the correct oil and following a prudent change schedule are essential for engine health.
- Oil type: Dexos1-certified 5W-30 engine oil, either synthetic or synthetic blend, as recommended by GM for the 3.6 L V6 in the Impala.
- Capacity notes: 6 quarts with a new filter; about 5 quarts if you’re not replacing the filter.
- Maintenance interval: about every 7,500 miles (12,000 km) with synthetic Dexos1 oil, or roughly 5,000 miles (8,000 km) if using conventional oil; shorter intervals may apply in severe driving conditions. Always consult the owner’s manual for your exact driving profile.
Following the manufacturer’s recommendations ensures proper lubrication and helps protect the engine over time. When in doubt, rely on the dipstick readings and the OEM guidance in your manual.
Summary
For a 2014 Chevy Impala with a 3.6 L V6, expect about 6 quarts of oil with a new filter (roughly 5.7 L); about 5 quarts if you’re not changing the filter. Use Dexos1 5W-30 oil and follow the maintenance schedule in your manual to keep the engine properly lubricated and performing well.
