Oil grade: ILSAC multigrade engine oil
Recommended viscosity: SAE 5W-30
Outside temperature
The 5W portion of the oil viscosity rating indicates the characteristic of the
oil which allows cold startability. Oils with a lower value before the W allow
for easier starting of the engine in cold weather.
The 30 in 5W-30 indicates the oil viscosity when the oil is at its operating
temperature. An oil with a higher viscosity may be better suited if the vehi-
cle is operated at high speeds, or under extreme load conditions.
How to read oil container label:
The ILSAC (International Lubricant Standardization and Approval
Committee) Certification Mark is added to some oil containers to help
you select the oil you should use.
SAE 5W-30 is the best choice for
good fuel economy and good
starting in cold weather.
If SAE 5W-30 is not available,
SAE 10W-30 oil may be used.
However, it should be replaced
with SAE 5W-30 at the next oil
change.
