SAE 1OW-30
As shown in the viscosity chart, SAE 1OW-30 is best
for
your vehicle. However, you can use SAE 5W-30
' if it's going to be colder than 60 OF (16 C) before
your next oil change. When it's very cold, below
O*F (-18*C), you should use SAE 5W-30.
These numbers on an oil container show its viscosity, or
thickness.
Do not use other viscosity oils such as SAE
1OW-40 or SAE 20W-50.
