The 2008 Honda Civic typically requires SAE 5W-20 motor oil, meeting API SN or newer and ILSAC GF-5. The engine capacity for oil is about 4.4 to 4.8 quarts with a filter, depending on the exact variant. Use a reputable brand and follow Honda’s maintenance schedule for best results.
Model variants and oil requirements
Two common configurations in the U.S. market drive the oil specification and capacity: the 1.8-liter inline-four engine found in most LX/EX models, and the Civic Hybrid. The core oil spec remains 5W-20, but capacities and service intervals can vary slightly by model. Always consult the owner's manual for the exact figure.
Base 1.8L Civic (2008)
Key oil requirements for the 1.8L engine are summarized below; use oil that meets the Honda-approved spec and viscosity for a broad temperature range.
Before listing the details, here is a quick summary of the essential points:
- Viscosity: 5W-20 is standard for the 1.8L engine in most climates
- Specification: API SN or newer; ILSAC GF-5 or newer
- Capacity: approximately 4.4 to 4.8 quarts with filter
- Change interval: follow Honda's Maintenance Minder; commonly 5,000 miles with conventional oil or longer when using synthetic oil, depending on driving conditions
In practice, many owners maintain the 5W-20 grade and adhere to the maintenance minder schedule, ensuring the top-off isn’t neglected and the filter is replaced at each oil change.
Civic Hybrid (2008)
The hybrid variant uses similar oil specs, but capacity and service intervals are tuned for the hybrid drivetrain; always verify exact numbers in the manual.
Before listing the details, here is a quick summary of the essential points:
- Viscosity: 5W-20 is standard in most 2008 Civic Hybrids
- Specification: API SN or newer; ILSAC GF-5 or newer
- Capacity: typically around 4.0 to 4.5 quarts with filter
- Change interval: commonly 5,000 miles with conventional oil; can be extended with synthetic per Maintenance Minder
Conclusion: The Hybrid generally follows the same grade (5W-20), but check your owner's manual for exact capacity and interval because variants exist.
Practical tips for selecting oil
Look for motor oil that bears API certification marks (e.g., SN or higher) and ILSAC GF-5 or higher. If you live in extreme climates or drive conditions, or you plan to extend oil-change intervals with synthetic, consult your manual or a Honda technician to confirm the best choice for your vehicle's needs and warranty requirements.
Maintenance guidance and intervals
Honda's Maintenance Minder system helps determine when to change the oil based on driving. For many 2008 Civics, conventional oil changes are commonly recommended around every 5,000 miles, while synthetic oil changes may extend to 7,500–10,000 miles depending on driving conditions and Minder readings.
Summary
For the 2008 Honda Civic, the standard recommendation is SAE 5W-20 motor oil meeting API SN or newer and ILSAC GF-5. The base 1.8L engine holds about 4.4–4.8 quarts with a filter; the Civic Hybrid uses a similar oil grade with a comparable capacity. Always verify exact specifications in your owner’s manual and use a high-quality oil and filter. Regular maintenance, guided by the Maintenance Minder, keeps your Civic running smoothly.
