I don't think the RON rating will affect the amount of heat generated by the engine.
It's more of the "I got high octane fuel on my car/bike so I'm going to floor this thing!" mentality which ends up with a hotter than usual engine
haha
I also have a digital engine coolant temp reading and no change in engine temps with different fuels if I just follow my normal driving in super traffic Cebu. Also I can't compare when on WOT since engine performance is different as I pull timing when I'm on 91RON fuel. But I'm guessing no difference in engine temps either.
