The 2015 Impala equipped with the 3.6 L V6 engine takes about 6 quarts of engine oil for a full change when you replace the oil filter.
That capacity comes from GM’s official specification for this engine. In practical terms, you’ll typically add around 5–6 quarts during an oil change and then verify the final level with the dipstick after starting the engine and letting it settle. Use a Dexos1‑approved 5W-30 synthetic oil unless your manual calls for a different grade for your market.
Official capacity and fill procedure
With a new oil filter, the total oil capacity is 6 quarts (about 5.7 liters). When performing a drain and fill, start with roughly 5 quarts and then top up to the Full mark on the dipstick after the engine has run and settled.
Oil specification and maintenance tips
GM generally recommends Dexos1 Gen 2 approved 5W-30 synthetic oil for the 3.6 L V6 in this model year. Always confirm the exact specification in the owner’s manual or on the fill cap, as regional variations can apply. Adhering to recommended maintenance intervals helps sustain engine longevity.
