8-1. Specifications

Outside temperature

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 easier 
starting of the engine in cold 
weather.

• The 20 in 0W-20 indicates the vis-

cosity 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 operated at high 
speeds, or under extreme load con-
ditions.

How to read oil container label:
The International Lubricant Specifica-
tion Advisory Committee (ILSAC) 
Certification Mark is added to some oil 
containers to help you select the oil you 
should use.

Engine oil selection (IS500)

“Toyota Genuine Motor Oil” is used in 
your Lexus vehicle. Use Lexus 
approved “Toyota Genuine Motor Oil” 
or equivalent to satisfy the following 
grade and viscosity.
Oil grade: ILSAC GF-6A multigrade 
engine oil
Recommended viscosity: SAE 5W-30
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 oil may be used. However, it 
should be replaced with SAE 5W- 30 
at the next oil change.
