However, be aware that mixing race gas and pump gas may not give you the octane level you thing. 50% 110 mixed with 50% 93 will not result in an octane level equal to the difference between the two. It will only race your octane a few points. If you are going to run over 22 psi, run straight race gas or as close to it as possible. I have melted two motors running "mixed".
I've heard this too. I think it's caused by the fact that lead is a big player in raising the octane of the 110/112/116 etc. grades of fuel, but there is NO lead in pump gas these days, thus the lead ends up far more dilute than you expect. The octane increasing additive packages are not compatible.
When you mix unleaded pump with unleaded race gas, the resulting octane can easily be calculated, i.e. a 50/50 blend of 91 and 100 nets the user 95.5 octane fuel.
Of course, I'm no chemist so I may be talking out my a$$.
BTW, 114 octane unleaded??? Wow!
