The 2003 Chevrolet Express offers ten different versions spread out across its three model lines: 1500, 2500, and 3500. The amount and type of engine oil needed vary depending on the specific model. For the 1500, the 4.3L V6 engine requires 4.5 quarts of SAE 5W-30 full synthetic oil, while the 5.3L V8 engine needs 6.0 quarts of the same oil. In case of emergencies, a temporary substitution with SAE 5W-40 is acceptable. Moving on to the 2500, the 4.3L V6 engine also takes 4.5 quarts of SAE 5W-30 full synthetic oil, while the other engines (4.8L V8, 5.3L V8, and both 6.0L V8 versions) all require 6.0 quarts of the same oil. The substitution guideline remains the same for this model line. Finally, for the 3500, all available engine options (4.8L V8 and two 6.0L V8 variants) call for 6.0 quarts of SAE 5W-30 full synthetic oil, with the same substitution allowance as previously mentioned.
