Wow, thanks so much! Had no idea there would be a tutorial on such a minor maintenance item. Appreciate it! George

Good question, have no idea. I am sticking with filter oil.
Briggs and Stratton suggests motor oil. That is all I have ever used. From what I have seen it is dirt bikes and boats that suggest the special filter oil. Not that others don't, I am sure someone will chime in with other manufacturers that suggest it. I would not over think it. Unless it keeps you up at night, just use what ever motor oil you have around the house. I am sure bar oil will be fine too. It is suppose to be a bit more tacky. I have it on hand but I want to save it for my chain saw. I often use 10w40 or 20w-50 for filters because I have some partially open bottles hanging around it is doubtfull I will use them for anything else other than an external lube. Good questions and good luck!
That is a good point rivets. I guess you can experiment and check the spark plug after running for a little bit. To your same point, would air filter oil do the same where is is not specifically specified? I dont have direct experience with air filter oil. I do with bar oil and I bet you would be fine but I do not really know. It is worth the check to make sure. With either.Bar oil will not allow the air to pass through the filter properly and may cause a rich running condition.
If you have no air filter oil any engine lubricating oil will work fine. I’ve always used SAE30 or 10W-30. Remember what IL posted, DO NOT SATURATED, use a teaspoon or two and squeeze out the excess.

FWIW
I lay the clean filter down, upside down so carb side is facing up
I dip my finger in the FILTER OIL then run my wet finger over the filter surface till the filter changes colour .
When there is a shallow layer of oil on the filter I let it sit foe an hour or more to allow gravity to drag the oil down into the filter.
Then it gets fitted to the mower

The lack of a fuel filter is intentional. Your mower's fuel tank is probably only an inch or two above its carburetor. It's a gravity feed system, and a filter would very likely slow fuel feed enough to starve the engine.
