Please do! I've never kept close enough track of where I fill up to really quantify any differences, but I've never noticed any significant difference in what kind of fuel I put in, or what additives.

I tried a cap-full of acetone for a few tanks and saw approximately no change, have put in a few of those gas-station fuel system cleaners now and then, and Seafoam'd it once as well.

My car runs as well on Shell 93 as it does on Pa's Discount 87 octane, gets 29mpg if I drive like an a**hole and 32mpg if driven like a granny.
