I was in Israel and noted that on all gas stations there is one for all - 95.

Probably the engines are tweaked for that...
I always though that high octane is for high performance motors.
But literally all from Hyundai 3 cyl and all other mini micro mid mass cars drink 95 there.

I am in Montreal Canada. The highest here is 91 in general. Really don't remember when last time I saw higher than that and on what gas station.

Even in my Lexus 350R 87 was written as recommended in the book. Was very cool to see.
Prior 2012 it was 91.

Any explanation about 95 on all general park of cars.

Thx

There are three major indices for gasoline octane rating: RON, MON, and AKI. AKI, used in the US and Canada is the average of RON and MON: (RON+MON)/2).
That 95 RON in Israel is probably 90 to 91 AKI in the US and Canada.

https://en.wikipedia.org/wiki/Octane_rating

When gasoline is subject to high taxes, the final cost difference between octane ratings becomes trivial. It's often not worth developing the storage, transportation, and dispensing infrastructure necessary to accommodate the various grades. The last time I was in the UK, I remember the two types of gasoline being premium unleaded and leaded. The wholesale cost difference between 87 AKI and 93 AKI in the U.S. is probably now less that $0.25. The really don't make 89 AKI. They mix 87 AKI and either 91 AKI or 93 AKI at the pump to produce 89 AKI.

BMW's need 91 AKI to perform as advertised. We don't have it where I live. So, I make my own 91 AKI by blending 1/3 87 AKI and 2/3's 93 AKI. That saves me about $3/tank and will save me about $800 over the 100k miles I'll keep my 26 MPG BMW.

My tree-hugger, hippie, socialist cousin bitches because her Smart needs 91 AKI. She's sort of going through a metamorphosis, though. She's worked hard, long, and smart in her life, and woke up one day a multi-millionaire. She's now lusting for a Range Rover. By definition, a tree-hugger, hippie socialist driving a Range Rover is no longer a tree-hugging, hippie socialist.
