Jeff (Goss):

Reid vapor pressure numbers are as follows...

...the lower the RVP number is numerically, the less volatile (i.e., harder to vaporize) the gasoline is.

Using your info, the C-12 is slightly less volatile than the Sunoco, however I would consider both fuels fairly close in range.

I would also compare the density of the fuels to determine impact on your carb settings.

And as Jeff Lee pointed out, I wouldn't mix them, unless you like hanging out at fuel check and answering lots of questions...
