The Honda Civic Si uses 0W-20 synthetic motor oil.
In current and recent Civic Si models, the 1.5-liter turbocharged engine requires 0W-20 synthetic oil. Honda recommends using Honda Genuine Motor Oil 0W-20 or an equivalent that meets API SP and ILSAC GF-6 standards. Exact oil capacity and replacement intervals vary by model year and driving conditions, so consult the owner's manual or a Honda service adviser for specifics.
Oil grade and compatibility
Model-year considerations
Most Civic Si models from the 2012-to-present generations with the 1.5-liter turbo use 0W-20 synthetic oil. Always verify for your exact year and climate, as some markets or special editions may have different allowances.
- 0W-20 synthetic motor oil (the standard viscosity for most recent Civic Si models).
- Fully synthetic formulations labeled 0W-20 that meet API SP and ILSAC GF-6 standards.
- Honda Genuine 0W-20 or equivalent from reputable brands (e.g., Mobil 1, Castrol, Pennzoil) approved for turbo engines.
Use a 0W-20 synthetic oil that meets API SP/ILSAC GF-6 standards and Honda's specification to ensure optimal performance and protection.
Maintenance and change intervals
Oil life depends on driving conditions and the vehicle’s maintenance minder system. Under typical use, many Honda owners run synthetic 0W-20 oils for about 7,500 miles between changes, while harsher conditions or short trips may call for more frequent changes. Always follow the maintenance minder or owner's manual for your exact interval.
- Consult the owner's manual or maintenance minder to confirm the recommended interval for your year and region.
- Use the dipstick to monitor oil level and ensure it remains within the marked range on level ground after the engine has cooled.
- Have the oil and filter changed by a qualified technician whenever the minder indicates, or at the stated interval, using 0W-20 synthetic oil.
Keeping to the recommended oil grade and change schedule helps maintain engine longevity and performance.
Summary
The Honda Civic Si relies on 0W-20 synthetic motor oil for lubrication. Choose Honda Genuine 0W-20 or a reputable synthetic oil that meets API SP and ILSAC GF-6 standards, and follow the owner's manual for capacity, intervals, and maintenance reminders. For year-specific guidance, consult the dealer or your owner's manual.
