I just did a search on oil analysis intervals. Would I be correct in trying to find a safe maximum oil change mileage # by oil analysis at...say...5K, and then maybe 3K intervals after that? In my case, the engine will be cleaned with Auto-Rx and then filled (probably) with Schaeffers Supreme 10w-30. Or is there a tried and true method of finding this #?
After finding this mileage #, can it be assumed that oil changes can be performed from then onward at that interval, providing the same types of oil and filter are used?
Thank you.
