How is Hi-octane Fuel not better for a GD 110cc engine?

[codenameir]

Hello friends.

I have heard from a few people that filling tank only with hi octane causes valve leakages or damages insides of the engine or carbeurator.

How's that even logical or possible?
Because that fuel is the most clean form of cumbustion. Why would it harm a 110cc's engine.

My personal experience with both type of fuels.

Regular = smoother bike , lesser fuel average per litre , lesser acceleration and top speed time increased.
Hi octane = slight increase in vibration , higher fuel average per litre , faster acceleration and reduced top speed time.

I find every thing better while using hi oct in my mahran ..
Like top speed
Acceleration
Milage

Wail hai, Be namazion k liye ..

Hi octane is good for any type of engine but mostly people make a 50:50 mixture of hi-octane with regular... Performance engine requires a 100% hi-octane with high octane number...

No need to put high octane in less cc bike

using higher octane fuel in an engine not designed for it (low compression) will result in thick soot/carbon deposits in the combustion chamber and valves and loss of acceleration/performance because it burns slower.

Cc have nothing to do with fuel type

I am using high octane only since day one in my gs 150, I need your suggestion on it my bike has clocked 1540 kms till now

Nothing is gonna happen with your bike engine if you use only hi octane i have used many times only hi octane in my gs 150 has clocked above 22k Alhamdolilah still going so strong

Hi Octane should not be used in engines with compression ratio of less than 10. My GS500 has compression ratio of 9.0:1, means I should only use regular fuel. Smaller bikes like GD110, GS150, CG125 etc should also use regular fuel.

If someone keep on using high octane would that damage the engine or what ?
