Most 2011 Impalas require about 5 quarts of engine oil when performing a standard oil change, while the high-performance Impala SS with the 5.3L V8 needs 6 quarts.
The exact amount depends on the engine installed in the car. In 2011, the Impala offered a 3.5-liter V6 for most trims and a 5.3-liter V8 for the SS. Oil capacity is stated with the filter installed; always verify the capacity in your owner’s manual and use the recommended oil grade, typically 5W-30.
Oil capacity by engine option
The following list shows the standard oil capacities for the two engines used in the 2011 Impala lineup. The figures refer to oil with the filter in place.
- 3.5L V6: 5 quarts (with filter)
- 5.3L V8 (Impala SS): 6 quarts (with filter)
These capacities provide a reliable baseline for a full oil change. If you have a different variant or a modified engine, consult the service manual for the exact figure.
Summary
Bottom line: plan for 5 quarts on most 2011 Impala models and 6 quarts if you own the SS with the 5.3L V8. Always confirm with your manual and perform the final check with the dipstick after filling.
