Engine Affected: 3.0L V6

Average Mileage: 61,437 mi (42,312 mi - 72,000 mi)


Sludge can build up in the engine because Toyota 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.
