If you are unable to find oils with the ILSAC certification
mark (“Starburst” symbol), an API classification SL, SL/CF
oil with the above label.
This mark appears on the top of the oil containers and has
two distinct areas for identifying various aspects of the oil.
1. The top portion will indicate the quality of the oil.
2. The center portion will show the SAE grade of the oil.
Recommended engine oil viscosity
Use engine oil with the proper thickness for the outdoor
temperatures where you will be driving.
SAE 5W-20, SAE 5W-30 and SAE 10W-30 engine oil can
be used in outdoor temperatures ranging from 0 °F to 100
°F (-18°C to 38°C). However, for optimum fuel economy
and cold starting, select the low SAE viscosity grade oil
for the expected temperature range. SAE 5W-20 or SAE
5W-30 engine oil is recommended.
