Has any one here used race fuel or 100+ gas in there 7th gen maxima I'm curious if I could

 

You probably could but what would be the point when 91 octane is the preferred fuel. The Max isn't a race car.

 

Prolly end up burning the rings out of her

 

The recommended fuel is 91 octane. Nissan specifically recommends against using octane boosting additives as they may affect the fuel system. The car performs great with the 91 octane, why ask for trouble?

 

On my 2 turbo cars adding 100+ octain made my cars run like a raped ape...higher the octain =the more boost i could run safely...but in a na motor like the maxima, i just dont see u getting that much of a gain in hp.

 

this won't do anything but burn a bigger hole in your pocket when filling up. unless you had a F.I. system and different tunes mapped to different octane fuel (1 being race fuel) this really won't net you anything

 

Let him do it. I'll be taking bets on which part of the car will fail first.

 

So we don't need to use 93 octane? I asked the dealer when I got my 04 about the notice on the gas cover saying premium fuel recommended he stated that it was mandatory so I've been using premium since 2004. If it doesn't make a difference I will stop using it.

 

91 is premium on the west coast. 93 is premium on the east coast.
That is what I have seen at least. Some places have 94 and 92 instead.

 

You don't have to use 91/93 in your 7th Gen. It is recommended for optimum performance. There are notices on the fuel door as well throughout the owners manual.

With gas, it's mostly a personal preference. I've been using it since 2006. I tried using 89 in my 2003 Maxima and that knocked like a b@stard.

My brother (2009 Maxima) used 89 octane in his car for about a year, then switched to 91/93. He mentioned numerous times that the engine was more responsive to the higher octane gas. Interestingly, he also said that he didn't experience any engine knock using 89, just that the car felt a bit sluggish.

In New England, 91/93 is considered Premium. Never seen 92 or 94.

 

I've used it in my car occasionally, and never saw a difference. 100, 105, 110, over that and it's aviation fuel.

Used to use it for dynoing, but then was convinced it didn't do much if anything, so I stick with the highest locally available at 91.

 

race fuel and 93-94 octane are two different things. it is recommended for optimum performance/fuel efficiency to use premium octane gas. race fuel is much higher than what you'd see at the average gas station

 

On the east coast 91 92 an 93 are premium depends where you go Wawa up in pa has 92 she'll has 91 and 93

 

Also depends on altitude, most high altitude places have 90 or 91 as the highest available.

As I travel south, and the elevation lowers, I can get 92 and once I get to the AZ border, 93 becomes available.

 

I use 91/93 the first 18 months with each Maxima (Have owned all gens except the first), then switch to midgrade (89 octane). Since I don't race the car, I have not been able to tell any difference between 89 and 91/93. And MPG is not connected to octane, so I always measure exactly the same fuel efficiency with 89 or 91/93.

I would simply stick with 91/93 except gas stations around where I live often charge 20 cents per gallon more to step from 89 to 91 octane. The marquees around here usually read something like $3.59, $3.79 and $3.99 for the three grades. I consider that to be a form of gouging. When in other areas of the country (and even other areas of this state), the difference between grades is usually only 15 cents or even less.

 

Good point!! Herein Texas I believe it's 4.09 for 93 octane but 3.70 for the 87. Definitely price gouging.

 

If anyone is familiar with Native American Pueblos, then, it's nice because they don't have to pay tax on stations on their property. So once in a while, you'll see a line from here to hell of cars lining up to fill up because the pueblo decided to have awesome prices that day.

I've got 4 pueblos surrounding me in every direction, so I see this quite often.

 

What I can't understand is how they charged or gas that's already been paid for. How do you raise the price of something that you set a price on, paid for a delivery, and have not had a delivery since the one that's already paid for? Are they anticipating the prices on the next delivery? What's going on there?

 

Sadly, the American creed is greed.

I live in a semi-rural area where many homes sit on larger land parcels, many of which are over 100 acres. That lack of density means the three nearby gas stations are usually not crowded, and gas deliveries are no more frequent than weekly. But during the wild price fluctuations of recent years, prices at those stations sometimes went up (always in sync) twice a day for days on end. No other word can describe this except 'gouging.'

93/97 is Premium in Alabama i sometimes get about 5 gal.of 110 races fuel an mix it to a tank of 93 an cant ask for better performance aswell as a thural cleaning of the fuel and intake system
