TFB reports that Froglube is Coconut Oil.
Fireclean is Canola Oil.
zMax is Mineral Oil.
Other lubes are petroleum oils.
Other lubes are synthetic oils.
Or oil blends.

Here’s my take:   Use whatever product that you feel works best for you.   If you like Frog Lube, use the Froglube.  Just because someone ballparks what the base oil is doesn’t negate the fact that the oil had been doing what it says it does and has worked well for you.  Nothing’s changed.
Yes, zMax is based on a mineral oil.   No, you are not going to get the same results using baby oil from the grocery store.  Why not?  Because the company took that mineral oil and ran it through some more refining processes and changed it.
Same with Frog Lube.  That’s not just plain coconut oil.  They added some components to it to take away the delicious flavor for one thing.  Trust me.   They also did something to make it smell like Kermit’s Ass.  And to keep it from congealing at lower than room temperature.   Coconut oil might be the base, but it no longer acts like it.  Trust me – My wife and I use Coconut oil for all kinds of things.  It’s great stuff.
The Fireclean though, I will not use any more.   Not even on my knives.   Not because it’s Canola… But because it gets sticky.  One of the shotguns I changed the stocks on, I had lubed generously with Fireclean… a year ago.  I’ve not worked with that gun since then.  You know what I found?
An action that did not want to move.
It was gummed up like it was full of pine pitch.    It took me about 3 Pink Floyd songs to clean it up and lube it with Breakfree CLP.
BREAKFREE!   I hate Breakfree!

So I’m not using Fireclean anymore because of the results, not the materials.  But yes, the materials did contribute to extended results here.

Still… Use whatever you like.  Just use it.   Because even if your choice of oil sucks – it’s a hell of a lot better than no oil.  And that’s a fact.
