Answer: The 2008 Honda Civic 1.8 L engine typically requires about 3.4 quarts of engine oil when performing an oil change with a new filter; without the filter, it’s roughly 3.1 quarts.
The 2008 Civic uses a 1.8-liter four-cylinder engine (commonly the R18 family). Oil capacity figures vary slightly depending on whether you replace the oil filter, and on the exact drain method used. This article lays out the official figures and practical notes to help you plan your next oil change.
Oil capacity for the 2008 Civic 1.8 L
Below are the standard capacities typically cited for this engine when changing the oil and replacing the filter. The numbers assume a complete drain and a new filter.
Before the following list, note that these figures reflect the typical factory specs and real-world practice may vary a little by filter brand and service procedure.
- With oil filter installed: 3.4 quarts (approximately 3.2 liters)
- Without oil filter installed: 3.1 quarts (approximately 2.9 liters)
For most oil changes, plan to have about 3.4 quarts on hand to accommodate the filter and any minor spill or measurement variance. After refilling, always recheck the oil level with the dipstick and top up as needed to reach the full mark.
Recommended oil grade and maintenance notes
Honda’s guidance for the 1.8 L engine in this era typically centers on a standard viscosity suitable for a broad range of climates. Always verify the exact specification in your owner’s manual, especially if you operate in extreme temperatures or under heavy load.
- Recommended viscosity: 5W-20 for most driving conditions. In certain climates or using vehicles with specific service requirements, 5W-30 may be acceptable per the manual or dealer guidance.
- Oil type: Use a conventional, synthetic-blend, or full-synthetic oil that meets or exceeds API service standards and Honda’s certification requirements.
- Oil changes: Follow Honda’s recommended interval based on driving conditions (often every 5,000–6,000 miles with conventional oil, or longer with synthetic oil).
Summary
The 2008 Honda Civic 1.8 L engine typically takes about 3.4 quarts of oil when you replace the filter, and about 3.1 quarts if the filter is not replaced. Use a 5W-20 (or as specified in your manual) and always recheck the level after adding oil. Having a little extra on hand during the change helps account for spill and measurement variances.
