87 octane for the 6th gen
For the first time ever, the Fuel recommendation for a Maxima is set at 87 with no mention of pinging or knocking.
History would tell you that the owners manual on any Maxima would recommend a 91 where 87 can only be used "as a last resort". This time around it's worded as follows:
Edit: Okay, so they just worded it differently. But it's still surprising to see that they recommends 87 first-hand where normally they'd say 91.

FUEL RECOMMENDATION
Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number. (Research octane number 91).
For improved vehicle performance, NISSAN recommends the use of unleaded premium gasoline with an octane rating of at least 91 AKI number (Research octane number 96).

This could actually be fairly significant. Note that they said that for "improved" performance, use higher octane fuel. This means that they may have "de-rated" the engine to 265HP/255TQ on 87 octane fuel. By re-upping the octane level to 91/93, suddenly 265HP/255TQ (on 87) could turn into 275HP/265TQ on premium fuel.
The new Accord V6 gains power over the manufacturer rating because of this. The Camry V6 (and Toyota 1MZ-FE engined cars) also gain about 10HP/10TQ by upping the fuel to premium from the recommended 87.
I can't wait to see some dynos!

IMHO if there is a slight power increase with the 6th gen it has to do with the dual exhaust.

Odd that your Manuals stats that, on mine it's clearly printed as:
"FUEL RECOMMENDATION
Use unleaded premium gasoline with an octane rating of at least 91 AKI (Anti-Knock Index) number (Research octane number 96) If unleaded premium gasoline is not available,unleaded regular gasoline with an
octane rating of at least 87 AKI (Research octane number 91) can be used."

Like you said, 6th genners might get some gains going up to 93. Who will be the first to try it out, though?

Premium gas is $2.35 where I live (near San Francisco) for 91 octane.
