I sold my Lexus GS300 and bought 2000 S500, has 98K miles on it. This car use Mobil 1 (0x40) about little over 8.5 quarts. I don't know much about the past maintenance on it. I would like to an Auto Rx if it is possible. Can any one suggest to me what oil and oil filter should I use. As you all know there is no warranty on it any more. Nothing wrong with it, run and drive fine. Thanks in advance.
