Identify the ISO 3448 viscosity grade from KV40, and the SAE J300 high-temperature engine-oil grade from KV100.
ISO VG (ISO 3448): grade = nominal KV @ 40 °C (cSt), ±10% band.
e.g. ISO VG 46 = 41.4 – 50.6 cSt @ 40 °C
Grades: 2·3·5·7·10·15·22·32·46·68·100·150·220·320·460·680·1000·1500 SAE J300 high-temperature grade (KV @ 100 °C, cSt):
SAE 8: 4.0–6.1 SAE 12: 5.0–7.1 SAE 16: 6.1–8.2
SAE 20: 6.9–9.3 SAE 30: 9.3–12.5 SAE 40: 12.5–16.3
SAE 50: 16.3–21.9 SAE 60: 21.9–26.1Only the high-temperature (KV100) SAE grade is determined here. Winter "W" grades require CCS, MRV and pumping-temperature data (SAE J300) not computed in this tool.
