Lexus IS300h 2013 Owner's Manual

5669-1. Specifications
IS300h_EE(OM53B95E)
Oil viscosity (0W-20 is explained here as an example):
• The 0W in 0W-20 indicates the characteristic of the oil which allows
cold startability. Oils with a lower value before the W allow for eas-
ier starting of the engine in cold weather.
• The 20 in 0W-20 indicates the viscosity characteristic of the oil
when the oil is at high temperature. An oil with a higher viscosity
(one with a higher value) may be better suited if the vehicle is oper-
ated at high speeds, or under extreme load conditions.
How to read oil container labels:
Either or both API registered marks are added to some oil containers to
help you select the oil you should use.
API Service Symbol
Top portion: “API SERVICE SN”
means the oil quality designation
by American Petroleum Institute
(API).
Center portion: “SAE 0W-20”
means the SAE viscosity grade.
Lower portion: “Resource-
Conserving” means that the oil
has fuel-saving and environmen-
tal protection capabilities.
ILSAC Certification Mark
The International Lubricant Specification Advisory Committee (ILSAC)
Certification Mark is displayed on the front of the container.
