Can I Save Money and Run Low Octane?
Article/dyno taken from http://www.dynospotracing.com
Granted it's not a Maxima, it should make you think twice before filling up with the cheap stuff.

Granted it's not a Maxima, it should make you think twice before filling up with the cheap stuff.
Here is a dyno chart showing two different cars. When I dynoed one of these cars, I knew that something was immediately wrong! Guess which one?
Notice that the 89 Octane car's power curves are very jagged. This is a result of the car "hearing" knocking and pinging and desperately trying to adjust the timing and save the engine. The ECU is almost searching for the best advance and having quite some trouble, not good.
The stunning results of running the lower grade fuel are -22 ft/lbs and almost -19 HP!!!! Ouch!
Folks, don't abuse the knock sensing capabilities of you beloved car. Let's just stick to the good stuff!

Only 91 in CA? Its 93 here in NJ and sunoco 94 Ultra.
Certain Sunoco stations sell 104 octane. They have over 110 + at our drag strips.

Yeah only 91... but I haven't been to the strip so I don't know if they have higher octane. They probably do though.
Feel free to use the link/article/dyno Calvin.
If you go to their dyno section, you'll see some nice jpg's of different cars (including M5, F355, blown E36, blown NSX, blown S2K, etc.).

Keep in mind, the reason some people see lower octanes is due to higer elevations. Parts of CA may only get 91 octane because they're higher up Same with Colorado.
Same with Colorado.

So I'd say to some extent the jury is still out until someone actually dynos a VQ with 87 and with 91. (however I'll be putting 91+ in my car once I get it.)
