: 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:
5W-30 and 10W-30:
API grade SL "Energy-Conserving", SM "Energy-Conserving", SN
"Resource-Conserving" or SN PLUS "Resource-Conserving"; or ILSAC
multigrade engine oil
15W-40:
API grade SL, SM, SN or SN PLUS multigrade engine oil
Recommended viscosity (SAE):
SAE 5W-30 is the best choice for
good fuel economy and good start-
ing in cold weather.
If you use SAE 10W-30 or a higher
viscosity engine oil in extremely low
temperatures, the engine may
become difficult to start, so SAE
5W-30 engine oil is recommended.
Oil viscosity (5W-30 is explained here as an example):
• The 5W in 5W-30 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 30 in 5W-30 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 operated at high speeds, or
under extreme load conditions.
