Problem: in my contry I have only 95 octane (regular) and 100, 100+ octane (no 98).
The price difference between 95 and 100 is almost 10%.

What would happen if I use 95 octane?

The knock sensor will detect the lower octane fuel and retard ignition timing (and possibly increase fuel a tad). While car will run/adjust, you will lose power and potentially a bit of MPG/KPL.

You have a high performance engine: the 10% fuel premium should not be financially strapping: if it is you got the wrong car.

Give the car the fuel it was designed to run with.
