■Recommended viscosity
GS460
SAE 5W-20 or 0W-20 engine oil
may be used. However, SAE 0W-
20 is the best choice for good fuel
economy and good starting in cold
weather.
GS350 SAE 5W-30 is the best choice for
good fuel economy, and good
starting in cold weather.
If SAE 5W-30 oil is not available, SAE 10W-30 oil may be used.
However, it should be replaced
with SAE 5W-30 at the next oil
change.
■ How to read oil container labels
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.

Oil viscosity:
● The 0W portion of the o il 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 20 in 0W-20 indicates the oil viscosi ty when the oil is at its operating
temperature. An oil with a higher viscosity may be better suited if the
vehicle is operated at high speeds, or under extreme load condition.
