93 octane =93 octane. There is no difference in quality fuel suppliers. If you go to Joe's cheap *** gas stop, you may well get what you pay for, but even then it will have come from a major refinery with a generic label.
Regardless of brand the only risk is in the handling of the fuel and the maintenance of the tanks.
BTW there are SO MANY more important things to worry about. lol

About the only way I can get 93 around here is to get it with 10% ethanol. ![grr](https://rennlist.com/forums/graemlins/cussing.gif)
No Cheveron stations around here. Shell is pretty proud of their fuel. Nearly $.10 more per gallons proud in my neck of the woods.

My mechanic told me that 101 Octane gas is very dry and it might melt a piston, told me not bother trying VP Racing fuels, said if I do, to mix it with a little oil...

Show me where Torco is less expensive. It is NOT.

The octane boosters I was referring too are the crap you find on the shelf at Pepgirl etc. Torco is an actual racing fuel company and supplier.

Of course this is assuming no change in boost.
15psi on pump vs 15psi on 100 octane you should notice very little difference if tuned properly.

Also, for the record, I'll just point out that Texaco is owned by Chevron, so its probably the same quality stuff. I'll check with my dad about that though... (chevron exec)

I just use STP Octane Booster, it's cheap and it has jet fuel in it and I do see a difference when I mix it with 5 gallons of gas...

You butt dyno is lieing to you. It takes a significantly greater amount of octane boosting additive/gal. to raise octane ratings. You already run 93 octane. If you really want to run higher octane find a Sunoco down there that sells 100 octane.
The STP stuff is one of the snake oil products that I referred too earlier. (unlike Torco) but it's your money...

As ehall said, do a search it's been discussed multiple times. Off the shelf boosters are completely ineffective as they add 0.1 of a point increase in octane. They are a effective $ play on our ignorance though - a money making scheme. It's misleading on the bottle when they say it adds points of octane. OTH, Racing fuel or xylene, toluene will truly boost your octane but will not increase performance alone. Higher octane simply let's you increase your engines output more safely by allowing you to increase fuel, timing, boost. Notice a I said more safely, not safely.
"101 Octane gas is very dry and it might melt a piston"
That's a new one...

If you use quality gas, like the Chevron gas that you use, then you aren't getting anything out of it.
