Lexus GS, S190 (EU)
Differential fluid capacity & service interval
Lexus GS, S190 (EU) differential fluid capacity ranges from 1,1 to 1,4 liters. Service intervals occur every 30000 km or 48 months. The data covers 8 configurations.

Additional Notes
- The rear differential fluid capacity for the Lexus GS 300 (2005-2007) is specified as a range of 1.15-1.35 liters, and the same capacity range applies whether conventional or synthetic fluid is used, indicating the fluid type does not affect the fill volume for that variant.
- The GS 300 produced from 2007-2010 carries a slightly reduced rear differential capacity of 1.1-1.2 liters, which is a narrower and lower range compared to the 1.15-1.35 liters specified for the 2005-2007 GS 300, reflecting a difference in the rear differential unit between the two production periods.
- Capacity ranges rather than fixed single values are common in differential service specifications because fill procedures typically involve adding fluid until it reaches the level plug opening, making the exact accepted volume dependent on the unit's orientation and residual fluid.
- The GS 430 for the 2007 model year alone carries a rear differential capacity of 1.3-1.4 liters, which is higher than the 1.15-1.35 liters listed for the 2005-2007 GS 430, pointing to a revised differential assembly introduced partway through the model's production run.
- The GS 430 (2005-2007) lists two separate normal-use fluid entries for the rear differential, both sharing the same 1.15-1.35 liter capacity and the same 30,000 km / 48-month interval, indicating an approved alternative fluid product exists for that configuration under the same service conditions.
- The Lexus GS 450h (2006-2012) and GS 460 (2008-2010) both share the 1.3-1.4 liter rear differential capacity range, aligning with the larger-differential specification also seen in the late GS 430 rather than the smaller unit found in the six-cylinder GS 300 variants.
- All configurations across the GS S190 range share a uniform rear differential service interval of 30,000 km or 48 months under normal use conditions, meaning the interval is governed by whichever threshold is reached first, a dual-trigger structure common in time-and-distance service schedules.
