Engine Oil

Recommended Posts

I just changed to pennzoil ultra, which I plan to run for about 10,000 miles.

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.

<_< 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 :cheers:
