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” or ILSAC
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 may be used.
However, it should be replaced with SAE 5W−30 at the next
oil change.
