I bet you could get the delta cost savings between premium and regular with driving style only.
If i drive like an aarp person can eake 50% better mlg. Then if the mood over comes you the high oct fuel is in your tank if you want hammer it!

I dont think anyone does not hammer it once in a while.
The NA55 is near 11:0 to 1 Compression ratio which requires proper fuel.
The tuning on this engine is not compatible with the amplitude or variation of fuel quality. Best to stick with what it requires.
A colder spark plug heat range will reduce detonation but also reduce the life of the plug and iridium is not as cheap as a fresh tank of ethyl.

Performance will suffer but otherwise there shouldn't be permanent damage to the engine. Just remember some localities have no gas with the minimum recommended octane. Certainly car makers don't expect avoiding regular gas if running low on fuel at those places.

As posted earlier, the ECU will retard the timing when it detects pinging (resulting in bad fuel economy and flushing any "price of fuel savings" down the exhaust port), but the timing doesn't stay retarded. The ECU slowly starts bringing the timing back to stock specs until it pings again. At that point it retards the timing and starts bringing it back again. This"retard and adjust until a ping is detected" dance will continue as long as substandard fuel is running through the system. The thing that some people miss is, the engine is pinging. It's not pinging as frequently as it would if the ECU wasn't repeatedly backing the timing off, but it is pinging. Pinging is horrifically bad for engines.

95 RON is the equivalent of 91 oct here in the states (the highest you can get in CA) and they sell as lows as 87 oct here which is the equivalent of 91 RON. I would not risk putting 87oct gas in my car.

psych
I find that people in commute to work or friday anytime are eager excited and in a general hurry or frustrated with light to light traffic.
Often people are at their best on the way to work unless its raining or icey cold. but really slow. The fast find trees and power poles comforting.
On the weekends its a toss up, either excited, relaxed or drunk. All good for an accident.
It is best to blast off when no one else is near and never in a resident community.
Cheers
