n Engine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Use Toy-
ota approved “Toyota Genuine Motor Oil” or equivalent to satisfy the
following grade and viscosity.
4.0L V6 (1GR-FE) and 4.6L V8 (1UR-FE) engines
Oil grade: ILSAC multigrade engine oil
Recommended viscosity: SAE 0W-20
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.
The 0W portion of the oil viscosity rating 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 oil viscosity when the oil is at its operating
temperature. An oil with a higher viscosity may be better suited if the vehi-
cle is operated at high speeds, or under extreme load conditions.
