I use "old" for my MOBI conversion because Calibre warns us that there will be display issues with the other two options in some devices. For KF8 I convert to AZW3. So my best guess, to answer your question, is that the MOBI format I'm using is for the pre-KF8 devices.

@DiapDealer - yes, I've come to that conclusion as well. Monospace fonts won't work for my book, I'm afraid.

@Susan_cassidy - thanks for your opinion, which I respect, but I've never liked the word "should."
writerkit:

If the book is not being prepared commercially, then having two versions is perfectly fine; you can determine where they are being provided, and, no problem. If you are preparing these books for commercial distribution, you have a different issue; you cannot provide two different files to Amazon for the same book, one in KF7, one in KF8. You must create a single mobi file that contains the styling for both.

Are you preparing this book for commercial sale and distribution? If you are, firstly, you should not use Calibre, because its conversions are often rejected at the KDP, for some reason or the other. Secondly, you'll need to learn how to code "fall-back" styling so that you can use embedded fonts in the K8 "portion" of the final mobi, but also achieve some discernible styling in the K7 version that's packaged in the mastermobi style. This is a way of using CSS to essentially tell the device rendering the book "if, then," so that if the device is Kf8 enabled, it uses the CSS, and specific CSS therein; if the device is KF7, it uses specific alternative coding for that device when it's delivered to the user.

I think that the wiki may have some tutorials you can use to learn this coding, and I think that Guido Henkel discusses fallback styling in his blog. Learning this level of coding is a bit much to be explained in a forum posting, particularly if (no offense) you don't even yet know that basic (old) mobi format doesn't even use CSS.

Hope that helps, at least a little,
Hitch
