    This is usually oil sludge and just keep having your oil and filter changed regularly and it should be fine

    Lexus changed/shortened the recommended oil change intervals due to a build up of sludge in these engines. Initially the oil change intervals were too long, great engine, change the oil every 3000 miles and should be all right.
