The 2008 Honda Accord EX uses 5W-20 motor oil. This viscosity applies to the model’s common engines, and you may use conventional, synthetic blend, or full synthetic oil as long as it meets the specified certification. Always verify the exact requirement on your car’s oil cap or in the owner's manual for your engine code.
The 2008 Accord EX was offered with both a 2.4-liter inline-four and, in some configurations, a 3.0-liter V6. Honda’s owner’s manual generally calls for 5W-20 across these engines, but check your specific engine version and climate. The correct oil grade is indicated on the oil fill cap and in the maintenance schedule, and your choice of oil should meet API certification and ILSAC GF-4 or newer standards.
Oil grade and specifications
Engine options in the 2008 Accord
Before listing the options, note that the oil specification is largely the same across the main engine choices in this model year, emphasizing a 5W-20 viscosity and API/ILSAC certification.
- Viscosity: 5W-20 is the recommended standard for both commonly available engines in the 2008 Accord EX.
- Oil types: Conventional motor oil, synthetic blend, or full synthetic are acceptable, as long as the oil meets API certification and the 5W-20 viscosity requirement.
- Certification: Use oil that meets API SN or newer and ILSAC GF-4 or newer standards.
- Brand: You may use Honda Genuine Motor Oil or a reputable compatible brand that meets the above specs.
Using the recommended 5W-20 oil and the proper certification helps ensure adequate lubrication, fuel efficiency, and engine longevity for the 2008 Accord EX.
How to verify the correct oil for your car
To confirm the exact oil specification for your particular Honda Accord EX, follow these steps:
- Consult your owner's manual and maintenance schedule for the exact oil viscosity and certification requirements.
- Inspect the under-hood oil fill cap, which often lists the required viscosity (for example, "5W-20").
- Check the API certification mark and ILSAC grade on the oil container you plan to use to ensure compliance.
- If you're unsure or your car has a unique configuration, contact a Honda service center or a trusted mechanic for confirmation.
In short, use 5W-20 motor oil that meets API SN or newer and ILSAC GF-4 or newer, with conventional, synthetic blend, or full synthetic options, and verify with the manual for your specific engine.
Summary
The 2008 Honda Accord EX takes 5W-20 motor oil across its standard engine options. You can choose conventional, synthetic blend, or full synthetic oil, as long as it meets API certification and the 5W-20 viscosity. Always check the owner’s manual or the oil fill cap for your exact engine and climate requirements, and follow Honda’s maintenance schedule to ensure optimal engine health.
