The Honda Civic Si uses 0W-20 synthetic engine oil, typically Honda Genuine Oil or an equivalent that meets API SN or newer standards. The engine’s oil capacity with a full change is about 3.4 quarts (roughly 3.2 liters).
Oil type and specifications
For the turbocharged 1.5-liter Civic Si, Honda calls for a low-viscosity, full-synthetic oil to optimize performance, efficiency, and turbo response. The recommended viscosity is 0W-20, and the oil should meet current API standards (SN or newer) and ILSAC specifications (GF-5 or newer). Using a reputable brand that meets these specs is important for warranty coverage and engine longevity.
Key standards and compatibility to look for when shopping for oil include:
- Oil type: 0W-20 synthetic
- Standards: API SN (or newer) and ILSAC GF-5 (or newer)
- Quality: Honda Genuine Oil or an equivalent from a reputable brand
- Capacity: Approximately 3.4 quarts (3.2 liters) with filter change
Following these specifications helps ensure proper lubrication, efficient fuel economy, and reliable turbocharger performance across climate conditions.
Maintenance schedule and practical notes
Oil change intervals for the Civic Si follow the vehicle’s maintenance minder and driving conditions. Under normal use with synthetic 0W-20, a typical recommended interval is about 7,500 miles (12,000 kilometers) between changes. If you drive under severe conditions—extreme temperatures, heavy traffic, or frequent short trips—the interval may be shorter, around 3,750 miles (6,000 kilometers). Always consult the owner's manual or the vehicle’s maintenance minder for the exact schedule applicable to your car.
If you’re performing an oil change yourself, prepare a drain pan, a new oil filter, the correct quantity of 0W-20 synthetic oil, and the proper drain washer if required by your model year. After refilling, recheck the dipstick and reset the maintenance minder as directed in the manual.
Summary
The Honda Civic Si requires 0W-20 synthetic engine oil that meets API SN or newer, with an approximate capacity of 3.4 quarts (3.2 liters) per change. Use Honda Genuine Oil or a reputable equivalent and follow the maintenance minder for interval guidance, typically around 7,500 miles under normal driving conditions. Always verify the exact specification in your owner’s manual for your model year.
