Team-BHP - View Single Post - How does high octane fuel improve performance?

I guess for all Euro II cars 87 Octane should be ok.

the contentious issue is about using higher octane fuel for Euro III cars.

The general opinion here seeems to be that Engines with a higher compression ratio benefit from the higher Octane.

So a Euro III Getz with a 10:1 compression shd benefit more from a 91 Oct Fuel as compared to a Euro III Baleno with a 9:1 compression ratio.

Hopefully someone can put more light on this.
