The use of engine oil additives could cause
dam age and invalidate the warranty.
E ng ine oi l vis cos ity
SAE 0W-30, 0W-40, 5W-30 or 5W-40
The SAE vis cosity rating defines the ability
of an oil to flow. W he n cold, oil is more
viscous than when hot.
Multigrad e oil is indicated by two figure s.
The first figure, followe d b y a W, ind ic ates
