VP C10 Fuel

I'm having issues with the ethanol gas. I have a Steve Wong chip programmed for 93 octane. Non ethanol 93 octane gas is getting harder to get here and I've been told that it will go away all together by the end of the year. I've contacted VP Fuels
and there is a local dealer here that I can get their fuel from. I'm not sure what would be best. I'm looking at their C10 which is a 96 octane, NO ethanol unleaded.
Question is... car needs 93, if I put 96 in it what would be the problems ?
Kinda thinking about some sort of a mixture, maybe a 75/25 mix, 75 being the VP.
I only drive my car on weekends, and then only if it is pretty outside so a tank of gas lasts me weeks.

No it should not be a problem using higher octane fuel, but keep in mind that you want to use the lowest octane you can before pre-detonation or timing retard occurs. I doubt that you would find much difference in performance between the two, (depending on the engine specs.)

What engine? Any modifications?

I don't think you've got anything to worry about using that fuel.
