If you cannot find oils with the ILSAC certification symbol,
use an API classification SM oil with the following label.
This mark appears on the top of the oil container and tells you
two important things about the oil.
API service symbol
1- The upper part indicates the quality of the oil.
2- The center part indicates the SAE grade of the oil viscosity.
Recommended engine oil viscosity
Use engine oil with the proper thickness for the outdoor tem-
peratures where you will be driving.
SAE 0W-20 engine oil is strongly recommended for optimum
fuel economy and cold starting.
If SAE 0W-20 is not available, the ILSAC certification oil of
other viscosity grades can be temporarily used.
