Just wondering who here uses octane booster?

I put some in my car last night, right before I filled the tank with premium 91 octane.

My car seems to be running better than before, and the occasional hard starting has seemed to be less.

The bottle says you can use it with every tank, but I would really not want to use it for every tank, I just decided to try it out for the heck of it.

Car seems to run smoother too.

I do not have my R-16 Resistor out either.

Is it me, or does it seem that gas stations may very well be selling lower rated gas at the premium pumps? I have major suspisions about this, and might get a gallon can and have it tested. The only time it ever ran poorly and started poorly was when I put some 89 in there once to see how the car would run.
