The S2000 typically uses synthetic engine oil with a viscosity of 5W-30 for most climates. In some markets or conditions, 0W-20 may be permitted by the owner’s manual. Always use oil that meets current API and ILSAC specifications and follow the vehicle’s manual for capacity and change intervals.
In practice, the Honda S2000 (AP1/AP2) relies on a high-quality, full-synthetic oil to handle its high-revving F20C engine. The sections below guide you through the recommended viscosity, the standards to look for, and practical maintenance details.
Oil type and viscosity
Here are the typical viscosity options and the standards to match when servicing the S2000.
- Default recommendation: SAE 5W-30 synthetic oil, preferably full synthetic, meeting API SN/SM or newer and ILSAC GF-5 or higher. Using Honda Genuine oil is common, but any high-quality synthetic oil that meets these specs is acceptable.
- Alternate option for certain climates: SAE 0W-20 synthetic oil may be allowed in some markets per the owner's manual; it provides easier cold starts and slightly better fuel economy, but ensure it meets the same API/ILSAC specifications.
- Track or extreme conditions: Some owners use 5W-40 or 0W-40 in very hot climates or on track days. This is not an official Honda directive, so consult your manual and consider the engine’s needs before switching.
Note: Always verify the correct viscosity for your specific model year and climate in the owner's manual and with a trusted service professional.
Capacity and change intervals
Know how much oil your S2000 holds and how often to replace it when you service the engine.
- Oil capacity (with filter): Approximately 3.1 quarts (about 2.9 liters).
- Oil change interval: With synthetic oil, 5,000-7,500 miles (8,000-12,000 km) under normal driving; reduce this for conventional oil or aggressive driving/track use. Always monitor oil level and use oil life indicator if equipped.
Regular oil changes with the correct viscosity and specification help sustain the S2000’s high-revving performance and longevity.
Practical notes
If you are unsure of your vehicle’s exact requirements, check the owner’s manual for the precise recommendations for your year and market, or consult a Honda specialist. Some owners also choose to use oil kits or brand-specific performance oils that meet the required spec.
Summary
For most Honda S2000 owners, the standard is synthetic 5W-30 oil, with 0W-20 as an allowable alternative in some regions. Use oil that meets API SN/SM and ILSAC GF-5 or newer, and plan roughly 3.1 quarts per change with synthetic oil every 5,000-7,500 miles (or sooner under heavy use). Always refer to the manual for your exact model year and climate.
