Pennzoil Marine Premium Plus 2-Cycle Synthetic Blend "TC-W3" okay in small air cooled engines?

Go to orileys and buy the quart bottle of Lucas 2 cycle oil for $10. It's got the correct ratings for your needs.

I dont support snake oil companies.
Maybe their 2 cycle oil is ok.. but with the other junk they sell.. I vote with my money.
I'd rather give VP Racing my money for JASO FD rated 2 cycle oil.

So I have been feeding a steady diet of 50:1 Pennzoil Marine Premium Plus 2-Cycle Synthetic Blend Oil into my Weed trimmers, chainsaws and backpack blowers for a number of years now without anything bad happening...

However I stumbed across some information that said the TC-W3 2 stroke oil is only for use in water cooled two stroke Marine applications because air cooled two stroke engines run much hotter. This got me thinking.... Have I been doing slow and/or unnoticeable damage to my equipment by running the TC-W3 oil??

Pennzoil also offers a "Pennzoil Premium Outboard and Multipurpose 2-Cycle Oil" that is both TC-W3 and ACI TC rated and when comparing their "flash point" and "viscosity" specs i don't see any significant differences.

I've also found ACI TC rated oil specs from other manufacturers with higher or lower flash points than both Pennzoils I've mentioned above.

Am I looking at the data all wrong? Why shouldn't I keep using the Pennzoil Marine Premium Plus 2-Cycle Synthetic Blend Oil TC-W3 rated oil in my little air cooled engines?

I really want to know how this could make any difference! I've attached spec sheets below....

I heard that Marine 2smoke oil gets fired in air cooled engines.
I've never decided I needed to test that theory as echo redarmor is probably just about the best 2stroke oil for the money, run it at 40:1.

So I took a trip to Walmart and picked up a few bottles of the VP Racing Full Synthetic 2 Stroke oil. I decided to use this going forward for peace of mind.... The other options for oil at this quality level are either more expensive or are unavailable locally. I am not convinced that this decision will make any difference however for the amount of oil I use as a homeowner the cost difference isn't going to kill me.... It is about 4x the cost of what I was using before!

I wish there was some long term testing available to show how the marine 2 cycle oil is insufficient. Throughout my extensive searching I have come across dozens of people who claim to have been using marine 2 cycle oil extensively without issues. Some of these posts have been from landscapers who are going through a lot of oil so the cost savings for them is important. I have not come across one test or person who has claimed that using marine oil has damaged or shortened the life of their air cooled equipment.

I see tons of info about how the air cooled 2 cycle oil is designed for higher flash points due to higher operating temperatures however I have found air cooled rated oil with lower flash points than the marine oil I was using. I've attached an example below. You can compare this to the data in my original post.
