The 2008 Honda Civic LX requires SAE 5W-20 motor oil as the standard viscosity. Use an API SN or newer oil that meets this grade, and plan to replace about 4.4–4.5 quarts with a filter during an oil change. Always check the owner's manual or the under-hood label for the exact specification and capacity for your specific vehicle.
In practical terms, the Civic LX’s 1.8-liter i-VTEC engine is designed to run best on 5W-20 oil across typical driving conditions. You can choose conventional, synthetic blend, or full synthetic oil, as long as it is 5W-20 and meets the API SN or newer standard. Following the maintenance minder and using the proper oil type helps protect engine longevity, fuel efficiency, and overall performance. If you live in extreme climates or have unique driving patterns, verify climate-specific guidance in the manual or with a dealer.
Oil specifications for the 2008 Civic LX
The list below highlights the essential oil specifications you should observe for this model year.
- Viscosity: SAE 5W-20 is the standard recommendation for the 1.8L engine in the Civic LX.
- Oil type and certification: Conventional, synthetic blend, or full synthetic oil is acceptable as long as it meets API SN or newer and the 5W-20 viscosity.
- Engine oil capacity: With a filter change, the Civic LX typically requires about 4.4 to 4.5 quarts (roughly 4.2 to 4.3 liters).
- Change interval: Follow the Honda maintenance minder; typical intervals range from about 5,000 to 7,500 miles depending on driving conditions and oil type.

Choosing the right oil and maintenance tips
Helpful guidance for selecting oil and staying on top of maintenance for the Civic LX:
- Confirm the oil meets API SN or newer and is labeled 5W-20; use ILSAC GF-5 or newer where applicable.
- Opt for Honda Genuine 5W-20 or a reputable equivalent that satisfies the same specifications.
- Fill to the correct level on the dipstick after an oil change (roughly 4.4–4.5 quarts with filter); recheck the level.
- Record oil change dates and mileage, and follow the maintenance minder recommendations to avoid premature wear.
Regular oil changes with the proper viscosity and specification help protect the engine, maintain performance, and support long-term reliability.
Summary
For a 2008 Honda Civic LX, the recommended oil is SAE 5W-20 that meets API SN or newer standards, with a fill of about 4.4–4.5 quarts including the filter. Use a conventional, synthetic blend, or full synthetic oil that matches these specs and follow the maintenance minder for intervals. When in doubt, consult the owner's manual or a Honda service advisor for climate-specific guidance.
