If hi octane is not recommended don't use. We use bcz our petrol comes with premixed with chemicals to save them money aka milawat which means we get less rons then expected but if we are getting good fuel then no need to go for hi octane unless recommended!
?Clear and simple... Fuel octane does not mean more or less engine power*
If you need 87 oct., putting 91, 92, or 115 oct. fuel in it will NOT gain you any power and in fact may cause you to loose power*
Higher octane fuel does not burn hotter*
In fact octane is the resistence to light/burn.*
So 93 octane fuel is harder to light and burns slower than 87 octane*
The only need for higher octane fuel is to controll the burn of the air/fuel.*
High compression engines needs the higher octane because the more you compressor air, the hotter it gets. If low octane fuel is used the heat in the chamber and the compression its self can light the air/fuel mixture it's self before the spark plug fires.*
If this happens, its lite at the wrong time and will cause detoneation (spark knock or ping) which will damage pistons, rings, valves, head gaskets, rod bearings*
Putting higher octane fuel than needed in a car does no harm to engine, but its just a waste of your money as theres no gains from doing so.*
Using lower octane than needed for your engine again will cause detonation and if left to happen for long enough it will do damage?
In simple words I say ?Hi Octane dal k gari ki adat kharab karni hai? ?
