I went to the Mobil 1 15000 synthetic and did some trials in both lexus ES & SC. I ran the oil for 10000 in the ES and changed it and it looked GREAT. I then put 12000 on the SC and it looked GREAT. I am doing 15000 now on both and expect the same results.

I use Amsoil 12mo/ 25,000 and it works great. I usually am closer to 16k after 12mo. Good luck!

<_< rumor is if your car is use to using dino stick to it cuz actualy most the slug build up is kinda good if you have like over 100 K on it. some of the slug from what i understand stops up those seals that may leak... with the syn.. it cleans out the slug which expose the seals that could leak..now this is just rumor i feel if you just settle down with high mileage oil and use oil treatment you car still be happy i use castrol high milage
