Probably not a HSV but theres still probably not a whole heap of difference other then a body kit a wee bit more power and harder suspension.
BTW the Monaro is just a 2 door commo
Don't you drive a merc with a huge naturally aspirated engine? The kind of engine least likely to benefit from a high octane fuel?
About the only thing Super is good for is making detonation less likely, so in a smaller more highly strung engine (particularly a turbo'd engine) the ECU will be able to push things further before the knock sensor goes off and it has to calm things down a bit. Usually this just means you can advance the ignition timing a bit more, it also means you can run more boost.
Yup the higher octane content in super causes the fuel to be harder to ignite, but, IIRC (and i'm not sure i do) more explosive when it does ignite. More of benefit to highly tuned (forced induction or high compression) cars and old japanese imports these days, our old fester ran lovely on super after it was converted to run unleaded but used to pink all over the place on peasant petrol.
If you aren't seeing any benefit from super then it's your own <expletive not used here> stupid fault for putting it in a car that doesn't need it.
Tesco oop nowerth is about a quid.. i use morrisons these days as i've found them to be consistently cheaper than the nearby tesco..98.3 last time i bought any petrol, diesel is still 10p a litre more than petrol, got the 5p off a litre on it last i filled it up.. coming up to needing some now so this is good news, unfortunately, I too have a many mile round trip across a city to get to an asda.. not worth it

a lot of older, early engines used to pink just after the changeover to unleaded. My grandad usd to have to run his Skoda Favorit on a mix, this he found out by accident after partially filling up with the super by mistake. It didn't pink anymore!
that'll be because the old engines were set up to use 98 octane fuel. Running on 95 = not so good. They weren't as marginal as performance stuff though, so that favorit it would have been just a case of finding the right mix to raise octane enough to stop it pinking..
Our fez used to run so bad on 95 it used to backfire unburned but on fire fuel out of the exhaust.. it was quite funny really, the clutch was worn when i got use of it so it'd groan every time you pulled off fast or on any kind of incline... groan, rev, popBOOM(sound of flames coming out of small pipe)groa-rrev.. the only engine i've ever heard run that bad was one i built from parts using a new and not set up carb, and the timing was a tad off so it ran like a DOG.. There was other issues with that engine in the fez though.. a dodgy auto choke made it occasionally refuse to start, sometimes it'd run way rich, when i got it the spark plugs weren't screwed in all the way, etc
as for the fez, convert it to manual choke (the later mk2s were auto choke.. this one was anyway, 1.1 pop plus), set it up properly, give it a good service, and start using super, it was fine till it got to be really old (and had about 90k on it) and then required its first 30 seconds to a minute of running to be almost entirely fuelled by WD-40 if there was any chill in the air..lol.. ah, good old days

The Monaro has been discontinued, the new Commodore is what we have as the VXR8. I've had one of those, albeit in 6 cylinder form, and frankly it was rubbish. I requested the hire company not give me another I disliked it that much. It's replacement, a previous gen Falcon XR6, was better.
I guess the HSV versions are much better, though. Not seen one on a rental fleet however.
