what kind of gas does everyone use?
And, whats the highest rated gas available in your respective areas?
I usually use Sunoco 94 Ultra, which is the highest rated gas you can get in Ontario. Although i'm not sure if theres a significance over using other station's premium 91 gas.
I have at times, noticed my milage is a bit better when I use 94, over 91 gas. (which becomes an irrelevant benefit due to the increased gas cost, but still interesting to note)

I use 87 most of the time and 89 on long trips when the car is fully loaded. But I have a VG with lower compression and higher octane would just hurt mpg and power.
VE's with their higher compression usually like the highest octane like you noticed. There are lots of MPG/gas threads to look through...

I didn't know 93+ existed.
In Cali and Nevada. I always see 87, 89, 91.
I typically use 76's (the gas station) or Chevron's 87. but I sometimes 91 as a Maxi-snack to give my car a treat if I have excess money.

I fill up on Mobil 87 only when desperate for gas.

:87 unless i am on a trip i go for 89 or 91. There are a few pumps around here in San Antonio that have 94 octane. I dunno where but from what I heard the jump in price is crazy. what bout VP racing fuel 109 octane. Or maybe nitromethane Oooooooo

I think they stop selling 94 in my area. Some people say that the octane doesn't make a diff. I did notice, while driving my girlfriends VQ, more rattling and of valves and and fiddly bits on 89. When I used 93 it went away. I do know that if you want some serious rattling and hesitating use some 89 in a ford with over 100k

I use the mid grade which is usually 89 around here. As for brand, mostly Citgo, though I have used Sonoco, and Hess a few times. I tried the regular 87 grade in it, but the car didn't seem as happy with the regular. It seemed that the power was a bit off, and it just didn't run as nicely.

I always use at least premium (which is 91) , but almost always try and get the 94 which can only be found at sunoco stations around here.
Only time I can recall it having less, was when my sisters BF borrowed it (without permission I may add) to get to work, and thought he'd do me a favour and filled it up on 87.
I knew immediately he did it after picking up the car as it ran like crap.
Soon after I had two dead injectors.. (which probably isnt just due to that one fill up, but interesting timing none the less)
Funny how in the UK, I recall them only selling 95 and 97 gas.

Yes, but if you have a VE engine, it runs much better on premium gas. It's prettymuch necessary if you want to maintain the engine.
On a GXE it's probably fine to use 87, but a good idea to use the good stuff now and then to keep the engine clean.

I heard you can buy 255 fuel in Atlantis
The fuel octane rating you find on sale in your particular area has been chosen by industry and government to be the best suited to the avg air density found there - less dense air needs a lower octane number fuel to ensure reliable ignition - you will find higher octane rated fuels (103/105) generally available at pumps when you are at sea-level (higher air density) - the higher you go the lower the octane requirement of the fuel to ensure reliable ignition in the same engine

Around here I always fill up with Shell V-Power 92 octane. 93 is available at most other stations, but I like the way the car runs on shell gas. 89 is OK sometimes, but at these prices, what's an extra dime a gallon?

On stock tune, 4th gens don't knock. use 87 if you want. I used to use 87 and never had a single problem.
Since I got my 5spd, I now use 93. I have no real reason, just for the extra 0.03 whp

There's a station on off of Central that sells 100, 105, 110. I think I've seen 92 or 93 in Las Cruces. Lucky to get over 90 here on the hill.
I've never put anything less than 90 in this tank. Don't plan on it either, not w/ my AFR/timing

I use 89 just to pamper my baby. I have done that since I began owning nothing but Maximas in fall of 1984. The reality is that Maxima engines IN PROPER TUNE run perfectly well on 87 (which my sister has used in her Maximas forever).
Every official test I have seen over the years by entities such as Motor Trend, Popular Science, Consumer Reports, etc, shows there is ZERO difference in mpg between 87 and 93 octane (highest normally available around where I live). The only detectable difference was the 93 seemed to give a very slight edge in extreme performance situations such as a timed quarter mile, and kept the engine very slightly cleaner.
Those saying the difference in price is 'only a dime' are lucky. Around where I live (south of Atlanta), many stations now charge 15 cents more for 89 and ANOTHER 15 cents more for premium. 30 cents times 17 gallons is five more bucks per fillup. Of course some folks could care less about money . . .
I'm not sure as to how many Maxima generations the following admonition applies, but with the 6th gen, the Owner's Manual says it takes the onboard computer around a full tank to both recognize and properly adjust to a change in octane, and that during that tankful, the engine is not running at full efficiency. It recommends strongly against changing octane more often than necessary.

i run 91 or 93
are you kidding me? it burns slower?
the octane rating tells you you how much the fuel can be compressed before it spontaneously ignites, (also known as exploding. burn = good, explode = bad) thus reducing the chance for a ping. Also, the higher the octane the hotter it burns. I would not say that it burns slower.
try a little bit of jet fuel (100 octane), that will beat any octane booster on the market!

I put 87 in my Maxima the first 3 months of ownership, and after getting a KS code and changing the sensor, it has only seen 93.
Mobil Super + 93 is all my car sees now. Even if I just paid $3.61 p/g to fill it up.
