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:
API grade SL "Energy-Conserving", SM "Energy-Conserving", SN
"Resource-Conserving" or SN PLUS "Resource-Conserving"; or ILSAC
multigrade engine oil
Viscosity grade:
SAE 0W-20, 5W-20, 5W-30 and 10W-30
Recommended viscosity (SAE):
If you use SAE 10W-30 engine oil in
extremely low temperatures, the
engine may become difficult to start,
so SAE 0W-20, 5W-20 or 5W-30
engine oil is recommended.
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 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.
