I've used mid-grade gas (Canada 91 octane?) since I bought this car (only 90,000 km) new. With the price of gas skyrocketing I'd like to know two things.
Yes it has electronic anti-knock. You can switch grades and it will adjust timing to avoid damage. You can run a google groups search on this ng with the term 'knock sensor' and you'll get a pile of relevant info.

Yes, but what you lose in MPG may make it a false economy.
And do a search, this has been answered several times in the last week.
Put in a tankful. If you don't notice any performance difference, your knock sensor is already shot and you weren't getting any benefit from premium. At the age of your car, it may just fall into that category.
If it turns into a dog (like 0-60 mph in 10 or 11 seconds), then you be the judge as to whether it is worth premium.
