Engine Oil Selection; Oil Identification Marks - Toyota 1997 Corolla Owner's Manual

ENGINE OIL SELECTION

Use API SH, "Energy−Conserving II" mul-
tigrade engine oil or ILSAC multigrade en-
gine oil.
Recommended viscosity (SAE):
SAE 5W−30 is the best choice for your
vehicle, for good fuel economy and
good starting in cold weather.
If you use SAE 10W−30 engine oil in
extremely low temperatures, the en-
gine may become difficult to start, so
SAE 5W−30 engine oil is recom-
mended.

Oil identification marks

Either or both API registered marks are
added to some oil containers to help
you select the oil you should use.
The API Service Symbol is located any-
where on the outside of the container.
The top portion of the label shows the oil
quality by API (American Petroleum Insti-
tute) designations such as SH. The cen-
ter portion of the label shows the SAE vis-
cosity grade such as SAE 5W−30.
"Energy−Conserving II" shown in the low-
er portion, indicates that the oil has fuel−
saving capabilities. Oils marked "Ener-
gy−Conserving II" will have higher
fuel−saving capabilities than oil marked
"Energy−Conserving".
The ILSAC (International Lubricant Stan-
dardization and Approval Committee)
Certification Mark is displayed on the front
of the container.
