    So, that's a no. Thought so, thanks for your technical consultation on this matter nevertheless!

    I have seen it but not on my vehicles, as I won't run a cheaper grade fuel with an elevated Octane.

    Ah right, crappy regular (low level) refined sulphurous gummy gasoline sludge propped up and made good with a shot of ethanol. Makes sense it's the shitty petrol not the ethanol that causes premature failure. Take United e10 as a clean, performance fuel example that competes favourably in our car by meeting the engine octane requirement, value for money, and brings additional benefits of ethanol.
    Even higher ethanol fraction fuel helps to prolong component life in our car generally, decoking the engine and promoting thermal efficiency under typical to high load. Perhaps because our Aussie cars are made for it but our Zeta injectors and pumps have clearly proven to last longer than with petrol in mass sample long-term testing, possibly due to reduced operating temps vs the spectre of oxidation and scoring from hydrous flow and storage.
    The one notable caveat being aftermarket high carbon (mild steel) exhaust systems which oxidise prematurely and spectacularly. However in this niche V8 performance sector two years between switching catbacks is almost acceptable, else shell out for stainless.
