2003 Chevrolet Tahoe Oil Capacity

The 2003 Chevrolet Tahoe with the LR4 engine takes 6.0 qt of oil and uses 5W-30 oil. These figures apply to the LR4 configuration listed here; other engines or model years may have different oil requirements, so do not assume this capacity applies across all Tahoes.

Use the capacity as the listed refill amount, and check the oil level after service rather than relying on capacity alone. If your engine or trim is not identified as LR4, or you need a figure not shown here, confirm the correct amount and grade on the door jamb or in the owner's manual.
