The 2017 Chevrolet Impala with the 2.5-liter engine typically requires about 4.5 quarts of engine oil with a filter change (roughly 4.3 liters). Always verify with your owner's manual or dealer for your exact engine and VIN.
The 2017 Impala offers a 2.5-liter inline-4 option in addition to a 3.6-liter V6. Oil capacity is important for proper lubrication and can vary slightly by production batch. This article explains the official capacity, recommended oil type, and how to check and perform an oil change on the 2.5L engine.
Oil capacity for the 2.5L engine
Common figures cited by manuals and service guides are listed below. Use this as a guide when preparing to change the oil on your Impala's 2.5L engine.
- Oil capacity with filter: about 4.5 quarts (4.3 liters).
- Oil capacity without filter (drain-only): about 4.0 quarts (roughly 3.8 liters).
Note: Some sources cite 4.7 quarts as the maximum capacity. Differences can arise from variations in dipstick measurements, filter choice, and whether the engine is completely drained. Always rely on the dipstick and the owner's manual for final confirmation.
Recommended oil grade and change interval
The 2.5L engine in the 2017 Impala uses a Dexos1-approved 0W-20 synthetic motor oil as the factory recommendation. Using a 0W-20 synthetic helps with cold starts and fuel efficiency while meeting GM's specifications.
Change intervals vary by driving conditions and oil type. With synthetic Dexos1 0W-20, GM typically recommends up to 7,500 miles (about 12,000 km) under normal driving, or 5,000 miles (8,000 km) in severe conditions. Always follow the maintenance minder or owner's manual for your vehicle.
- Dexos1-approved 0W-20 synthetic motor oil (or equivalent meeting Dexos1 specs).
- Alternative: 0W-20 synthetic meeting Dexos1 if Dexos1-labeled product is unavailable.
In all cases, ensure you replace the oil filter with every change and reinstall the drain plug with the correct torque. Then check the oil level with the dipstick after adding oil and letting the engine run briefly.
How to check and maintain oil level
To ensure you have the correct oil quantity after a change, follow these steps:
- Park on level ground and turn off the engine. Wait a few minutes for the oil to settle.
- Open the hood and locate the dipstick; pull it out, wipe with a clean rag, reinsert, then pull it out again to read the level.
- If the level is low, add small amounts of oil (about 1/2 quart or 0.25 liters) at a time until the dipstick shows within the proper range.
- Reinsert the dipstick and close the hood; run the engine for a minute or two, then recheck the level to confirm it remains within the proper range after settling.
- Check for leaks around the drain plug and around the oil filter immediately after changing the oil.
By following these steps, you ensure proper lubrication, engine protection, and accurate oil level readings.
VIN-specific verification and resources
Oil capacity can vary slightly by manufacturing batch and engine tie-in with VIN. For the exact specification for your vehicle, check these sources:
- Owner's manual under Engine Oil and Lubrication.
- GM's official service portal or dealer service desk using your VIN.
- A trusted repair manual or workshop service guide for your 2017 Impala 2.5L.
Always use the vehicle-specific data to confirm the exact oil capacity for your VIN, especially if you recently replaced the engine or changed attachments that might affect capacity.
Summary
For a 2017 Impala with the 2.5L engine, plan for about 4.5 quarts of engine oil with a filter change, using Dexos1-approved 0W-20 synthetic. Confirm with the owner’s manual for your exact VIN and follow best practices for checking and maintaining oil levels to ensure optimal engine performance.
