■Engine oil selection
“Toyota Genuine Motor Oil” is 
used in your Toyota vehicle. Use 
Toyota approved “Toyota Genu-
ine Motor Oil” or equivalent to 
satisfy the following grade and 
viscosity.
Oil grade: ILSAC GF-6A multigrade engine 
oil
Recommended viscosity: SAE 
0W-20
Outside temperature
SAE 0W-20 is the best choice 
for good fuel economy and good 
starting in cold weather.
If SAE 0W-20 is not available, 
SAE 5W-20 oil may be used.
However, it must be replaced 
with SAE 0W-20 at the next oil 
change.

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  viscosity characteristic of the 
oil when the oil is at high tem-
perature.
How to read oil container label:
The International Lubricant  Specification Advisory Commit-
tee (ILSAC) Certification Mark is 
added to some oil containers to 
help you select the oil you 
should use.
