Considering I just filled up my car today and payed 1.53 a liter. I'm quite sure It costs me 1.53 a liter.

Not sure what you're paying, but I also didn't make a guess.

It is 1.63 here.

I normally run 92 octane ethanol free, but if I'm not near an E0 station I use 91 octane Chevron.

In the colder months it doesn't seem to make much difference.

Not only have you proved it by just being observant, but it is proven by dynos that the ECU for the FA20 stock is heavily effected by temperature changes.
