Long drains are all about convenience. You've said so yourself in noting that you ran a 7.2K drain interval because you were busy with more important things.
Oil is cheap, but if you can change it less often without imperiling the engine in any way, then why wouldn't you?
Longer drains mean that when I hit 15% MM, I can start to plan the drain for when it works for me.
Long drains also mean that I can easily span the winter or at least wait for a warm dry day.
This may not mean much in Cali, but it can be huge here.
True, I was watching a Mercedes mechanic on YouTube talk about long drain intervals and he was saying anything over 80000 miles on the engine you should really start doing oil changes around the 6,000 mark this is one engine wear darts occurring more rapidly. I used to do Long Haul Trucking and the company would do oil changes every 30000 miles but when engine oil would hit about 15,000 miles on it I start going through about a gallon about every week and a half so I think as the oil ages it starts breaking down and you start going through more of it in my honest opinion when you find this Mark probably a good time just to go ahead and change it anyways regardless of what kind of oil you're running
