The 2004 Chevrolet Express needs 4.5 quarts of 5W30 synthetic oil for its base engine, the 4.3L V6, and 6 quarts for the 5.3L V8. It's recommended to change your oil every 7,500 miles or once a year, whichever comes first, to improve engine life, gas mileage, and performance. Synthetic oil is superior for performance as it reduces friction and protects the engine, unlike synthetic blend oils that mix synthetic and conventional oil.
