Sludge Buildup on Engine Due to Infrequent Oil Changes: Lexus GS300 Engine & Powertrain

Problem overview

Sludge can build up in the engine because Lexus did not recommend frequent enough oil changes. Lexus will sometimes offer a discount on cleaning the engine if necessary. Owners who changed their oil every 3,000 miles did not experience these problems. This sludge build up can lead to excessive oil consumption.
