The 2012 Chevy Volt’s 1.4-liter range-extended engine requires about 4.5 quarts (roughly 4.3 liters) of engine oil when you change the oil with a filter installed. Without the filter, the capacity is around 4.0 quarts.
Oil capacity and maintenance implications
Understanding the exact capacity helps ensure you use the correct amount during an oil change and maintain proper lubrication for the Volt’s generator-assisted gasoline engine.
- Engine oil capacity with filter: 4.5 quarts (4.3 liters).
- Engine oil capacity without filter: about 4.0 quarts (3.8 liters).
Knowing these figures helps you plan oil changes accurately and avoid overfilling or underfilling the engine oil.
Oil type and grading recommendations
Using the right oil is essential for lubrication, emissions compliance, and optimal performance in the Volt’s 1.4-liter engine that acts as a generator when needed.
Recommended options include the following Dexos1-compliant grades.
- Dexos1 Gen 1 5W-30 motor oil
- Synthetic blend or full synthetic oils that meet the Dexos1 specification (5W-30)
Always verify the exact specification on the oil container or consult the owner's manual or a GM service advisor for climate-specific guidance.
How to perform an oil change on the Volt
Below is a general sequence you can follow when changing the engine oil, noting the 4.5-quart capacity with filter as the standard reference.
- Warm the engine briefly to operating temperature to ensure complete drainage, then park on level ground and set the parking brake.
- Wipe away debris around the oil fill cap and the drain plug; place a drain pan beneath the oil pan.
- Remove the drain plug and allow the used oil to drain completely; replace the drain plug with a new washer if required, and install a new oil filter.
- Fill with the recommended amount of oil: about 4.5 quarts (4.3 liters) with the filter; check the level using the dipstick and adjust if needed.
- Run the engine for a minute, turn it off, recheck for leaks, and recheck the oil level again after a few minutes of rest.
Following these steps helps ensure a proper oil change and accurate level readings, using the correct Dexos1 5W-30 specification where applicable.
Summary
The 2012 Chevy Volt holds roughly 4.5 quarts (4.3 liters) of engine oil with the filter installed, and about 4.0 quarts (3.8 liters) without the filter. Use Dexos1 Gen 1 5W-30 oil (synthetic blend or full synthetic that meets Dexos1) and consult the owner's manual or a GM service professional for climate-specific guidance. Regular oil changes with the proper amount and spec help maintain reliability in the Volt’s unique range-extended setup.
