What kind of oil does a 2004 Acura RSX Type S take?
The 2004 Acura RSX Type-S uses SAE 5W-30 motor oil, preferably synthetic or a high-quality synthetic blend, and it takes about 4.5 quarts (4.3 liters) when changing the filter.
The RSX Type-S is powered by the 2.0-liter K20A2 engine. The owner's manual generally calls for 5W-30 oil in normal driving conditions, with synthetic or synthetic-blend options providing better protection and performance. Climate and driving style can influence the ideal choice, so always verify guidance in your manual or with a dealer if you’re unsure.
Recommended oil type and viscosity
In practice, most RSX Type-S owners run a 5W-30 grade oil. The following options are commonly used, with full synthetic preferred for maximum protection:
Choosing the right oil
- Full synthetic 5W-30 motor oil (e.g., Honda Genuine, Mobil 1, Castrol, Pennzoil, etc.)
- Synthetic blend 5W-30 motor oil
- Conventional 5W-30 motor oil (acceptable only if synthetic options are unavailable; ensure it meets API certification)
For best protection and longevity, most RSX Type-S owners choose a high-quality synthetic 5W-30 oil and adhere to the recommended change intervals.
Oil capacity and top-off considerations
The engine oil capacity for the RSX Type-S (K20A2) is approximately 4.5 quarts (4.3 liters) when performing a full oil change with a new filter. Use a compatible oil filter and recheck the level after filling, ensuring the dipstick reads within the proper range.
Maintenance intervals and practical tips
Oil-change intervals depend on the oil type and driving conditions. With synthetic 5W-30, typical intervals range from 5,000 to 7,500 miles (8,000 to 12,000 km) under normal use, and shorter intervals (3,000–5,000 miles / 5,000–8,000 km) for severe service or hot climates. Always follow the vehicle’s maintenance minder or the owner’s manual if available, and adjust for climate and driving style.
- Schedule changes around your driving conditions; track or aggressive driving may require more frequent changes.
- Install a high-quality oil filter with every oil change.
- Check the oil level monthly and after long trips; top up with the same viscosity if needed.
- Use the recommended oil viscosity and certification (API-certified, suitable for your engine).
- Dispose of used oil at an approved recycling facility.
Regular oil maintenance helps protect the high-revving K20A2 engine and maintains performance and efficiency.
Summary
For a 2004 Acura RSX Type-S, use SAE 5W-30 motor oil, preferably a synthetic or synthetic-blend formulation, with an approximate capacity of 4.5 quarts (4.3 liters) including the filter. Choose a reputable synthetic 5W-30 and follow the manufacturer’s recommended change intervals based on driving conditions and climate. Always refer to the owner’s manual or your dealer for the most precise guidance.
