Do the math.
If there WAS a fuel additive that gave you 10% better mileage, and a bottle
cost $5 to treat 21 gallons, you'd only be breaking even with it with gas
at $2.40.
Most of the fuel additives that claim to improve mileage wouldn't save you
any money, even if they DID do what they claim. Which they don't.
I will say that there is a major exception to your statement, though: one
fuel additive that some people need is lead substitute.

OK Scott, I'm doing the math. I'm adding two gallons of gas for $4.80
as a fuel additive and pocketing the other 20¢ for my piggy bank. My
mileage did go up 10%!
And here's a tip. You must add the two gallon "additive fuel" first
before filling the tank or there won't be enough room.

Yeah, and you also have to do the hokey-pokey and turn yourself around,
knock three times on the ceiling if you want the mileage increase (twice
on the pipe if it ain't gonna show), etc
