Ok, here's the deal. I have 86K on my Sienna V-6. I have changed the oil at 4,000 - 8,000 miles with dino oil. Last year, I used valv. high mileage synth blend 5-30. I went 8K miles with this. I am now running PP in it. Since their advertisements mention cleaning out a system, should I go with a lower mileage oil change for the first go around? Or, will I be fine with a filter change midway through?
Thanks,
Dan J
