Actually the manual says 87 ... RECOMMENDED 91/93 for maximum performance.

Yeah, I got banned for a week or two for advocating 87. Even the manual says you can use it as long as you do not get a knock. It goes on to say that region to region and gasoline brands might be different, so you can check around for some good 87, if you don't find it just put some octane booster in your car.
My knock sensor went out at about 200,000 miles and I used 87 for about 50,000 miles and the car now has 250,000 miles with no signs of damage. Recently I have been switching around with 87 and above but not lately.

I only use 91 octane. I put 87 in my previous 98 Maxima and it ran like crap. Horrible gas mileage (filled up twice a week) which I can only guess came as a result of the 87 (ruined knock sensor?), although I'm no mechanic so I can't say for sure. Putting the 91 in my new Maxima, I fill up every 10 days and I think the performance is better.

91+ for me, and about the octane booster and all of the fuel additives, i had a friend that put all that crap in his jetta and ended up stalling in the middle of the highway because his fuel filter or something clogged up. the mechanic says its because of additives, but it could be just because it was a jetta! but....91+ for me

I've used 87 for the past 4 years. I've put more than 30,000 miles on it with that gas.

You will loose ponies if you do not go with the recommended grade, it is recommended for a reason. Just like the NGK plugs, they are recommended for a reason (people have had issues with other less expensive plugs, and in they ended up putting the recommended plugs in - go with copper if you want to save cash). There was a thread a while back where someone put their car on the dyno and they lost quite a few ponies from going down to 87 octane.
Why would you put something in your car that will hurt its performance
? What is the purpose of adding/spending money on mods if you will be putting this lower grade of gas in 
?

my max performs just as good on 87 as it does when i use 91. i dont notice any difference, and i get great mpg either way. more expensive gas, is just, well, more expensive. i personally think its a mind over matter thing, ppl gotta buy the most expensive thing for there ride all the time becuz they think that more expensive is always better. it usually is, but i wouldnt say it is in this case.

its not for performance wise, our car is recommeneded to run on 93. its like walking outside with no shoes you dont have to but its recommended so you dont get blisters and shiet. lol bad analogy but you get the point

"For maximum performance use premium unleaded fuel" means exactly that. I don't think Nissan put that statement on the gas cap for the he-ll of it.
