| – | 4.5 qt. (4.3 L, 3.8 Imp. qt.)u IS500 |
| – | 8.3 qt. (7.9 L, 7.0 Imp. qt.) |
The engine oil capacity is a reference quantity to be used when changing the engine oil. When actually adding the engine oil, make sure that the oil level is between the low level mark and refill upper limit mark (P.291). Warm up and turn off the engine, wait about 5 minutes, and check the oil level on the dipstick.
Engine oil selection (IS350 AWD/IS350/IS300 AWD/IS300)
“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 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.
Outside temperature
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.
How to read oil container label: The International Lubricant Specification Advisory Committee (ILSAC) Certification Mark is added to some oil containers to help you select the oil you should use.
