Just chuck some redx in it and show her the bottle, she will think she's piloting a fighter jet by the blurb written on the bottle and the placebo affect.I was thinking it wouldn't make much difference in performance but if I tell the wife I have put more expensive fuel in it to give her car a bit more oomph she will believe me.
But how long was it sitting for? Year or two? How did you store it?I just go by personal experience, when you've seen what fuel can do when left too long you try and prevent it.
This was an MV Augusta, I had to strip the tank and entire fuel system. Not a nice job and not the only one.
Modern cars will "tolerate" E10 but it's a backwards step, a cheap filler to bulk out the petrol.
The tank is sealed but air must be sucked in to replace the fuel that is used, cars have carbon canisters and "evaporative emissions control" but that is to vent excess pressure when tank heats up.
I wouldn't want E10 sat around in a car that is infrequently used.

I think you've gone well beyond any reasonable argument here.But how long was it sitting for? Year or two? How did you store it?
And you know there's a difference between something sitting around with very little fuel in a cold garage and something that takes a while to get used?
I've currently got 1 bike that's been sitting for 10 years, and another 2 that sit for 6 months at a time.
They don't get left with full tanks, no fuel stabiliser, nothing.
Fuel is replaced by air when it is used, that's the key, it doesn't suck the moisture from it in, when not used.
If you think about it, what byou're actually suggesting is that your tank will always be full because the air has so much moisture it will fill the empty space constantly.
If anyone is actually filling up once a year, you bought the wrong car, and needed a full EV.
Like I say, it's being overthinked here, and if you're really worried, just floor the car once a month, bring the petrol engine in for a mile or two. I doubt there's anyone that isn't using the ICE at least once a month.
Don't be too aghast, your understanding of octane ratings is incorrect. A higher octane fuel is not "more combustible", it is simply more compressible before detonation. It doesn't contain more energy or necessarily burn easier.Sorry guys, but there's so much mis- information here, I'm aghast.
All fuel can have water in it, its more important that the garage ensure the tanks are purged than the fuel you use.
It doesn't make water, it can absorb moisture, but tanks are sealed, and it doesn't contain it unless the garage messes up with their tanks. But the reality is we're talking about 5% extra.
A litre of ethanol is 34% less combustible than pure petrol, so another 5% is negligible.
Put 5% more water in your pint and see if you notice a change.
Your brake fluid is the same, if not worse but no one is taking the same precautions due to water, we leave that in for years.
And if your car is affected by a fuel with approx 1.7% less combustibilty, and you notice, I'll be amazed.
A higher RON rated fuel can give more power and mpg, simply because it allows the injection rate to be closer to lean running, safer than normal unleaded or is more combustible giving more power, which can also allow me mpg in the right conditions.
It's just as susceptible to bad garages.
Your posts are always to the point @keithmac and always with excellent pics. As well as that you never seem to be “aghast” too often 🤔A fair few vintage bike owners strip the Ethanol out completely with Dyed water.
I've seen first hand what it does to carbs, most now are either hand lapped metal fuel needles or Viton tipped.
Any water in a fuel tank just sits at the bottom, not an issue with a plastic tank (unless it gets sucked through fuel system) but will rot a metal fuel tank from inside out.
Every fuel system job I get in I drain the tank down completely and check for water, out of 20 carb jobs this year at leas 5 have had excessive water content.
Bottom picture is ethanol damage to a vintage carb, that was a lot of work to get back in good running order.

Cheers!, seen it all before, nothing surprises me nowadays!.
You do know all about MTBT tuning surely? (Minimum Timing for Best Torque), and best torque output is a lot richer than Stoichiometric (14.7:1).A higher RON rated fuel can give more power and mpg, simply because it allows the injection rate to be closer to lean running, safer than normal unleaded or is more combustible giving more power, which can also allow me mpg in the right conditions.

Some vehicles require super unleaded to attain full power, but can run perfectly happy on lower standard fuels.
