The 2004 Chevrolet Impala requires 5w30 oil and holds 4 quarts. Using high-quality oil is essential for optimal engine performance. Eventually, you will encounter issues with the oil, which can lead to engine malfunction. Signs of bad oil include a strong burning smell, indicating a need for immediate inspection to prevent potential damage or even an explosion. Additionally, engine knocking noise and decreased gas mileage are common symptoms of oil problems. It is recommended to replace the oil every 5,000 to 10,000 miles to prevent engine issues from arising.
In the 2004 Chevy Impala, the standard 3.4L V6 engine requires 4 quarts of 5W30 synthetic oil. If you opt for the bigger 3.8L V6 engines available for the Impala, each of these versions will need 4.5 quarts of 5W30 synthetic oil.
My 2004 Impala with a 3.8-liter engine was consuming oil, so I switched to Shell Rotella 10W-30 T-4, which has excellent cleaning abilities. This helped resolve the oil consumption issue before the next scheduled oil change. I typically use 5 quarts of oil in my car.
