Dear Friends,
I have gotten my test results back on my motor oil. As some of you know, I don't change my oil anymore, I just change the filter. What my test results show, it that my theories are wildly correct. Namely, those theories are:
The key to clean oil (at least in my case) is change your filter a lot and keep the oil topped off. The result is the oil stays clean and viable like new. There is no reason for me to dump the oil pan again. It matters not if I dump the pan at 3k, 17k, 25k, or 50k miles... the results would almost be the same.
Here is the background letter sent to Blackstone, you'll have to join the Hyundai-forums website to see the pdf, since I don't know how to attach it here. Click link and join:

Hi there, how are you?
This oil is my experiment in mega-extended oil. It currently has 51,000 miles spanning more than 3 years methinks. The purpose of the testing is test the viability of the oil, as opposed to testing the viability of the motor in normal oil testing. The wear-metal content is a secondary consideration, although useful to know.
The oil used is a soup of various synthetic oils, later changing to Super Tech High Mileage.... mostly 5w-30 oils. Filters were cheap Super Tech, and later cheap Purolator. Engine burns/leaks about 1 quart every 4K. Filters were changed “when I thought it looks dirty” at about 3K.
This oil represents the worst possible state I think it's ever been in, since I used this filter change cycle to pull my over-weight boat quite often.... reducing my MPG almost 50%. In other words, this batch was used HARD. This sample was taken from the filter, and the experiment continued.
So I will do the full range of tests... Wear-metal and TAN. I believe the cost you charge for all that is $35. I believe this oil is clean and viable, what I worry about is acid content, thus the TAN test. I'm not worried about TBN since I know it gets a constant flow of fresh oil... it's “looks clean” anyways.
If this oil tests okay, I'll be shooting for 100k for my next test.
See ya, John”
