The oil you should use depends on which engine your 2004 Accord EX has: the four‑cylinder version typically calls for 5W-20, while the V6 version uses 5W-30. You can use conventional, synthetic blend, or full synthetic oil as long as it meets Honda’s specifications and is appropriate for your climate.
Engine options and oil requirements
The 2004 Accord EX was offered with two engines, and each has its own recommended viscosity. The following guide outlines the required oil grades by engine type.
