SAE VISCOSITY GRADE
Oils are classified in accordance with SAE (American Society of Automotive Engineers) standards.
The relationship with ambient temperature is shown in the table below.
(A higher number corresponds to a higher viscosity)
SAE Ambient temperature °C
SAE 30 48.9°C ~ 0°C
SAE 20 33.3°C ~ 0°C
SAE 20W 26.7°C ~ -12.2°C
SAE 10W 15.6°C ~ -23.3°C
SAE 5W -12.2°C ~ -34.5°C
SAE 10W-30 48.9°C ~ -23.3°C
SAE 10W-40 58.9°C ~ -23.3°C
Ø Use an oil with smaller number (lower viscosity) in winter and one with larger number (higher viscosity) in
summer.
Ø Multi-grade oil has all-round stability under seasonal and temperature changes.
SAE10W-30, for example, is applicable for all seasons. It has a viscosity equivalent to SAE10W at a low
temperature and provides a lubrication effectiveness corresponding to SAE30 during operation.
SERVICE CATEGORY
When selecting the correct engine oil for an engine application, refer to:
SAE : viscosity grade
API : service category (American Petroleum Institute)
CCMC : service category (Comité des Constructeurs du Marché Commun)
GASOLINE FUELED ENGINES
Always use SF, SG, SH or SJ class oils in general purpose gasoline engines.
DIESEL FUELED ENGINES
Always use CC or CD class oils in general purpose diesel engines.
Select the correct type of engine oil, conform with the
engine temperature operating conditions.
- Electric starter type: -15°C ~ 40°C
Recoil starter type: -15°C ~ 40°C
-
Kerosene fuel type: +15°C ~ 40°C
