Oil identification marks
API Service Symbol ILSAC Certification Mark
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 anywhere on the outside
of the container.
The top portion of the label shows the oil quality by API
(American Petroleum Institute) designation such as SH.
The center portion of the label shows the SAE viscosity
grade such as SAE 5W−30. “Energy−Conserving II”, shown
in the lower portion, indicates that the oil has fuel−saving
capabilities. Oils marked “Energy−Conserving II” will have
higher fuel−saving capabilities than oils marked
“Energy−Conserving”.
The ILSAC (International Lubricant Standardization and
Approval Committee) Certification Mark is displayed on the
front of the container.
CHECKING THE ENGINE COOLANT
LEVEL
 1
Reservoir cap 2
Upper line 3
Lower line
Park the vehicle at a level spot and look at the see−through
coolant reservoir when the engine is cool. The coolant
level is satisfactory if it is between the upper and lower
lines on the tank. If the level is low, add ethylene−glycol
type coolant.
The coolant level in the reservoir will vary with engine coolant
temperature. However, if the level is on or below the lower line,
add coolant to bring the level up to the upper line.
Use only ethylene−glycol type coolant. It will prevent freezing
and corrosion. Neither supplemental inhibitors nor additives
are needed nor recommended. (For information on
ethylene−glycol coolant, see also “Engine coolant selection”
described below.)
