The 2005 Chevrolet Express Van useS4.5 quarts of oil with the 4.3L V6 engine or 6 quarts with the 5.3L V8 engine. Chevrolet recommends that You use SAE 5W-30 synthetic oil whenever You need to change it. There are two types of oil on the market these days that are very common, synthetic and conventional. Synthetic oil is engineered in a lab to give You greater wear protection and longer life than the standard petroleum based conventional option. This means You will need to change it less frequently, usually 7,500 miles for synthetic and 3,500 to 5,000 miles with conventional. I recommend checking Your oil at least once a month to make sure that it is full and free from any signs of debris.
