Testosterone: The New Synthetic Oil

[goliath1812]

It is easy enough to change the filter without doing a complete oil change, if that's something to be worried about. However, I also am using Royal Purple synthetic filters that are also rated for extended periods. My oil analysis also came back fine, showing the filter working well after the 7000 miles. In fact, this has been a regular thing for me, I just haven't had an oil analysis done until my last change. With the car being 6 years old, and over 120,000 miles I have seen nothing but good coming from the oil I use, the way I have been using it. Would the analysis show the same if I had been using dino oil with Frame filters? Maybe, but I sure wouldn't want to try going 7,000 - 8,000 miles on them without a change.
