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-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.

How to read oil container label

The International Lubricant Specification Advi-
sory Committee (ILSAC) Certification Mark is
added to some oil containers to help you select
the oil you should use.
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.

Recommendation of the use of low emissions gasoline

Gasolines containing oxygenates such as ethers and ethanol, as well as reformulated
gasolines, are available in some cities. These fuels are typically acceptable for use,
providing they meet other fuel requirements.
Lexus recommends these fuels, since the formulations allow for reduced vehicle emis-
sions.
