On my modified n/a I'll throw in the lowest octane I can plus a bottle of premix. In south dakota, the low/standard grade is 85 avg oct. i did see 83oct once, and was considering trying it just to see how it would do, but didn't need any gas at the time. Can't remember where that was though.
N/a's don't need anything great. Basicaly low octane = better power and mpg on an n/a. Same doesn't hold true for an charged engine, but n/as love low octane fuel
EDIT:
and if by "die faster" you mean the engine will blow apart, those peeps are wrong. They are thinkig that higher octane is so much better, but its not true for n/a cars. However, on a turbocharged/supercharged engine, the fuel needs HIGHER octane to keep from detonating before the spark.
Basicaly the lower octane mans fuel burners and combusts easier, great for an n/a.
The higher the octane, the harder it is for the fuel to burn and combust, good for protecting a turbocharged engine.
For a turbo, compressed air + low octane fuel (burns easier) will combust before it ever gets the spark of the sparkplug. This is detonation. This is bad. This kills engines.
However, a turbo engine: compressed air + high octane fuel (harder to ignite) will not spontantiously combust, and will hold true until it hits the spark from the sparkplug, to which it combusts like it shoud.
Detonation (caused by low octane in a turbo'd engine, or just stupid tuning) is bad for the engine. How bad? Ping ping, blown engine bad. So yeah... they are right, it will cause it to "die faster", but only in turbo/supercharged engines.

The disadvantage? EVERY fill up, you *MUST* add the correct amount of premix, RELIGIOUSLY. A couple missed tanks, and your engine starts to lose compression and power... another tank or two and pop goes the wankle.

Take it from my experience..use as low an octane as you can. I kept putting in premium for the first 6 or so months before I found out you're not supposed to. It took a bit of injector cleaning to get my car back to normal from the unburned deposits that it had left.

Nurse I need 1300cc's NOW
to beat a dead horse some more .. its a giant waste of money .. especially where i live. to put anything other than 87 in on a NA . i burn gas like crazy(also doesnt help i drive very fast)

MMO is apparently not bad to throw in every now and then, but it's not designed as a premixing oil for primary lubrication. Any decent 2-cycle oil will work (most people tend to go with the cheap Walmart stuff without any problems).

So for my '87 GX (Non Turbo) which fuel would I preferrably use? My motor is a 7k13P; rebuit with less than 2000 km's on it.
(Please excuse me if the information above has already provided an answer. I'm not sure what N/A stands for; except "not applicable".)

Not knowing what N/A was referring too, I felt it prudent to double check. Thanks for clarifying that for me. Again, I appologize for my ignorance of most of the terms.
Also, the manual had suggested I used 91, which also prompted me to check with "those who know."
Oh, and to answer your question, it appears that it was said 6 times on this thread prior to me asking. I guess it was the seventh one that I needed to understand.

hmmmm x2....Perhaps I misread or have my numbers mixed up. That wouldn't surprise me one bit. I'll have to double check when I get home, just for the fun of it.
