How much oil does a 2004 Impala 3.4 take?
The 2004 Impala equipped with the 3.4-liter V6 typically requires about 4.5 quarts of engine oil (roughly 4.3 liters) for an oil change, including the new filter.
In practice, the exact amount can vary slightly due to how long the oil has drained, the oil filter, and whether the filter is replaced. Always verify the level with the dipstick after filling to reach the full mark on a level surface.
Oil capacity and recommendations
Key figures and tips
Before performing the oil change, note these points to ensure you use the right amount and follow proper steps.
- Oil capacity: 4.5 quarts (4.3 L) with a new oil filter; about 4.0 quarts if you do not replace the filter.
- Recommended oil grade: commonly 5W-30 (conventional or synthetic) depending on climate and driving conditions; consult the owner's manual for the exact specification.
- Fill and check procedure: drain completely, install a new filter, pour in roughly 4.0–4.5 quarts gradually, start the engine to circulate oil, turn off and let sit a few minutes, then top off to the full mark on the dipstick.
- Maintenance interval: follow the schedule in the owner's manual, typically around every 3,000–5,000 miles depending on driving conditions and oil type.
Concluding note: after topping off, recheck the level with the engine off on level ground and adjust as needed to reach the full mark without overfilling.
