API SN이란 무엇인가요? 업계 표준 API 디코딩
API SN (American Petroleum Institute Service Category SN) is a critical engine oil classification introduced in 2010, succeeding API SM with enhanced protections for modern engines. TERZO recognizes API SN as the baseline for high-temperature deposit control,sludge prevention및emission system compatibility – particularly vital for vehicles using ethanol-blended fuels up to E85.
Key improvements over API SM include:
1. 51% better piston deposit protection (TEOST MHT test ≤35mg)
2. 12% lower gelation risk for cold starts
3. Phosphorus content optimized (0.06-0.08%) for catalytic converter safety
For drivers wondering “what does API SN mean?“, it signifies oils that:
✔ Protect turbochargers (critical for TERZO’s 5W40 API SN SuperSynth series)
✔ Extend oil change intervals (validated by TERZO’s 32M km road tests)
✔ Maintain viscosity in ethanol-fueled engines
1.While API SP (2020) offers advances like:
1. 35% better LSPI prevention
2. Improved chain wear resistance
2.API SN remains essential for:
1. Pre-2020 vehicles (covers 78% of global fleet)
2. Cost-effective maintenance (TERZO 15W40 API SN saves 18% TCO)
3. Moderate-climate operations
3.Key differences at a glance:
| 매개변수 | API SN | API SP |
|---|---|---|
| Phosphorus Range | 0.06-0.08% | 0.05-0.08% |
| Turbo Protection | Baseline | Enhanced 40% |
| Fuel Economy | Moderate | 1.5-2.5% better |
TERZO’s ACEA C3 vs API SN dual-certified oils bridge both standards for European vehicles.
