■Recommended viscosity
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 may be used. However, it
should be replaced with SAE 5W-
30 at the next oil change.
■How to read oil container labels
Some oil containers are labeled wi th ILSAC certification marks that
help you to select the proper oil.
Temperature range anticipated before
next oil change.

*: 5W-30 is an oil that provides optimal levels of fuel efficiency.
Oil viscosity
●5W oils are for use in areas where the ambient temperature is -3F (-25C) or
above. "10W" oils are for areas where the ambient temperature is -4
F (-20C)
or above. Oils with smaller figures are better for engine starting in cold weather
and fuel efficiency.
● XX-30 indicates oil viscosity. Oils with higher numbers have better sta-
bility at higher temperatures and are good for high-speed driving.
