2006 2007 2008 2009 2010 2011 2012 2013 Lexus IS
| Engine | Oil capacity | Oil type (viscosity) | |
| 4GR-FSE IS250 | without filter: 2WD models AWD models | 6.2 qt. (5.9 L, 5.2 Imp. qt.) 6.3 qt. (6.0 L, 5.3 Imp. qt.) | SAE 0W-20 |
with filter: 2WD models | 6.6 qt. (6.3 L, 5.5 Imp. qt.) 6.7 qt. (6.4 L, 5.6 Imp. qt.) | 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 engine oil capacity is a reference quantity to be used when changing the engine oil. Warm up and turn off the engine, wait more than 5 minutes, and check the oil level on the dipstick.
Continued engine operation with low engine oil will damage the engine.
Functions of engine oil
Engine oil has the primary function of lubricating and cooling the inside of the engine, and plays a major role in maintaining the engine in proper working order.
Engine oil consumption
It is normal that an engine should consume some engine oil during normal engine operation. The causes of oil consumption in a normal engine are as follows.
Oil is used to lubricate pistons, piston rings and cylinders. A thin film of oil is left on the cylinder wall when a pistonmoves downwards in the cylinder. High negative pressure generated when the vehicle is decelerating sucks some of this oil into the combustion chamber. This oil, as well as some part of the oil film left on the cylinder wall, is burned by the high temperature combustion gases during the combustion process.
Oil is also used to lubricate the stems of the intake valves. Some of this oil is sucked into the combustion chamber together with the intake air and is burned along with the fuel. High temperature exhaust gases also burn the oil used to lubricate the exhaust valve stems.
Oil consumption: Max. 1.0L per 1000 km (1.1 qts./600 miles, 0.9 Imp. qts./600 miles) When judging the amount of oil consumption, keep in mind that the oil may have become diluted, making it difficult to judge the true level accurately.
For example, if a vehicle is used for repeated short trips and consumes a normal amount of oil, the dipstick may not show any drop in the oil level at all, even after 1000 km (600 miles) or more. This is because the oil is gradually becoming diluted with fuel or moisture, making it appear that the oil level has not changed.
The diluting ingredients evaporate out when the vehicle is then driven at high speeds, as on an expressway, making it appear that oil is excessively consumed after driving at high speeds.
