●If low quality oil or oil of an inappropriate
viscosity is used
●When driving at high engine speeds or
with a heavy load, or when driving while
accelerating or decelerating frequently
●When leaving the engine idling for a long
time, or when driving frequently through
heavy traffic

*: The engine oil capacity is a reference quantity to be used when changing the
engine oil. Warm up and turn off the
engine, wait more than 5 minutes, and
check the oil level on the dipstick.
■Engine oil selection
“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-5 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.

starting of the engine in cold
weather.
• The 30 in 5W-30 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.
