I fit each of those categories and have been changing oil for half a century. Paying a certified mechanic for such a simple job, in my mind, is like paying a brain surgeon for a haircut.
If you worked in a shop like I do and fixed so many DIY jobs gone wrong, your tune might be different. Just knowing what is the proper spec of oil is not that simple these days. Just witness how this thread has gone wrong. I bet not 5% of folks know what dexosD spec oil is.
"Just throw some Rotella in it" say some folks, "it'll be fine" they say. It's not their $$$ on the line.
Knowing what oil and filter is good, as well as knowing what OTHER stuff needs addressing is key. THAT'S where most DIYers and lube shops go wrong.
To each their own. It doesn't affect me nor my business. I only try and give the best advice I can.
