Something else it helps in with these classic cars, since we all pretty much have ethanol fuels now, is it appears to me to keep corrosion in the fuel system at bay.
Like I've mentioned I've used it for 25 years or so in all the classic cars, a couple of them daily driven, some sit for periods of time, but all of them have never had a single issue with the fuel system. I've had carbs apart for one reason or another, jetting, playing with things, and they always looks spotless inside, no white corrosion or anything of the sort. My fuel filters look great (cleanable filters with mesh screens) and I seem to get decades of use out of fuel pumps now both mechanical and electrical (in tank) setups. The 2 cycle oil puts lubricity back into the fuel and that's a good thing. That's what leaded fuels used to do.

So lots of benefits other than just lubricating the top of the engine.
