Petronas RON95...

Yesterday my car engine had its first taste of RON95 petrol... What I can said was the engine runs smoothly... Is there any performance deficit from RON97??? The answer is 'NO'... It drives just like RON97... The engine rev smoothly to the red line as well... But all this is base on my so call 'butt dyno'... At first I was a bit skeptical to try it out but after trying it, guess I will be switching to RON95 from now on...
