The 2008 Accord uses 5W-20 oil for the 2.4L four‑cylinder and 5W-30 for the 3.0L V6; you can use conventional, synthetic blend, or full synthetic as long as the oil meets Honda's specs.
Engine-specific oil requirements
Below is a quick reference for the two engines that powered the 2008 Accord lineup, including the recommended viscosity and typical capacity.
2.4L inline-4 (i-VTEC): Recommended viscosity is 5W-20 for most climates. Oil capacity with filter is about 4.4–4.5 quarts depending on the model and drain procedure.
3.0L V6: Recommended viscosity is 5W-30. Oil capacity with filter is about 5.0 quarts.
Always verify the exact specification for your specific model and market, as some regions or conditions may influence the requirement.
Oil types and standards
For the 2008 Accord, you can choose from conventional, synthetic blend, or full synthetic motor oils. The important part is that the oil meets the proper viscosity and industry standards and Honda's service recommendations. Look for the following on the bottle and label:
- Viscosity: 5W-20 for 4-cylinder, 5W-30 for V6
- Compatibility: API service category appropriate for your vehicle (look for API SL/SM or newer, as applicable)
- Brand compatibility: Honda service oils or reputable third-party oils that meet Honda's specification
Using a higher-quality synthetic oil can offer better protection and longer intervals between changes, but always follow Honda's recommended change intervals for the engine in your climate and driving conditions.
Maintenance tips and intervals
Regular oil changes are critical for the Accord's longevity. The standard change interval for many owners is every 5,000 to 7,500 miles with synthetic blends, and every 7,500 miles or longer with full synthetic, depending on driving conditions and oil type. Check the owner's manual for the exact interval and service reminders.
Where to find the exact specification
If you're unsure which engine you have or where to find the recommended oil, you can locate the information on the under-hood oil cap or the owner's manual: the label on the engine bay and the section on engine oil or maintenance schedule will list viscosity and capacity. When in doubt, consult a Honda dealer or a trusted repair shop with your vehicle's VIN to confirm the correct specification.
Summary
In short, a 2008 Honda Accord typically uses 5W-20 oil for the 2.4L four-cylinder and 5W-30 oil for the 3.0L V6, with options ranging from conventional to full synthetic as long as standards are met. Always verify the exact specification for your engine and climate, and follow Honda's recommended change intervals.
