Hello all,

Two questions, a) what's your MPG, and b) if I continously put regular unleaded would I hurt anything other than the check engine light coming on? I am not being penny wise, but the way the prices are going up every little bit helps especially if your other car is a V8 ...

thx,

 

Dude...

lol...

93 is 10 or 20 cents more. It's not like your fillup is going to cost $40 more. JUST BUY 93 OCTANE. It might not help your MPG, but it'll burn cleaner and leave less garbage in your engine.

Plus...in NY at least...gas has dropped from $4.30 for 93 to $3.85. IT'S CHEAP.

 

Your car is a V6. I would put in what the manufacture recommends. In this case a minimum of 91 octane rating which equals premium fuel.

 

a) my mpg ranges between 24-31 b) the ecm will compensate if you use lower octane gas but the engine will not run optimally. it normally wont cause a SES light just for that. but as stated above you should use the manufacturer recommended octane, its worth the extra buck or two ay fill up.

 

I've been putting in 87 for years with no ill effects and no check engine light. I've been getting 26 mpg 90%+ highway driving for the past 6 months or so (will probably drop when the winter gas mixture is out).

using lower octane fuel can cause knocking especially at lower altitudes. It could potentially foul your o2 sensors due to excess junk in your exhaust. Most people on the org have reported better mileage after using premium. I couldn't tell you for sure though because haven't every put anything less than the manufacture recommended 91 octane

 

That might be a little overkill...

I will probably put some race fuel in at the world of speed challenge. 110 octane probably wont help any but i figure if i am going to run my baby up to top speed i might as well give her a treat.

 

I get 42 mpg consistently in my 4th gen...

Seriously, everyone's MPG will vary depending on climate, driving conditions, mechanical condition of the car, maintenance, etc. There are 1000 threads out there just like this.

 

With a relatively light foot, following the speed limit and driving conservatively, I get between 26-33 mpg. The number obviously goes up as highway driving increases and goes down as city driving increases. The car is always fed a diet of 93 octane.

 

I put 93 in mine and my car was running sluggish and the gas flew out the window... had to fill up 4 days later!

 

93 always in mine, anywhere from 21 to 26

 

I get 25mpg mixed driving (half-half) using 93. My car, since November of 2006 when I got it and started re-doing all the maintenance, has seen nothing but synthetic fluids and 93 octane gas.

My car is one of the best running cars I have ever encountered. NO ISSUES. Zero, zip, nada.

 

17 MPG is what I see out my car. of course your mileage will vary W I D E L Y based on driving style, time, distance, temperature, weather, time between drives,etc.

 

Damn you guys are lucky. everywhere I live 93 has ethenol in it. The only things without eth are 87-89-91. ;O Ethenol sucks!

 

whats wrong with ethanol? i always use premium and here in texas($3.61 by the way) it all says 10% ethanol... my car runs great and gets 21mpg consistently in the city

 

 

i dont really get very good gas mileage since i put my foot down quite often, but i do fill up with 91 and drive about 300 miles (city and highway) before i have to fill up

 

I get about 22-25 city depending on how heavy my foot is and ive gotten around 30-31 highway... ive only used premium fuel...its recommended by nissan and its burns much cleaner...i put 87 in once cuz i was cheap...and i paid with bloody knuckles and a $50 knock sensor

 

I get about 350mpg using 87 fuel.

 

"I get about 350mpg using 87 fuel."

Dakid712.......YOU WIN!!!!


I get about 26mpg on the highway in my stock '97SE 5-spd w/ K&N air filter. Here in CO our available octane numbers are 2-points lower than you guys closer to sea level (I'm at 5000'). The low end is 85, I tend to mix the 89 mid-grade and 91 upper grade that we have. Seems to work well.

whoah!
that beats out my 10cc moped!

 

I get infinity mpg using no fuel

I just push my car to save money... every little bit counts, right?

 

Liar.

You use up 500 calories per every 100 ft pushed. Therefore...your actual mileage is 26,400 calories per mile.

 

 

LOL!

i dont get very good mileage...... im a freaking lead foot. i like to push the maxima to the max everytime i drive
btw, the little note from the manufacturer on the inside of the gas door says "premium fuel recommended for maximum performance." recommended... hmm now why would the manufacturer take the time to recommend us to fill up with premium? probably for MAXimum performance from our MAXima. they meant to say USE ONLY PREMIUM. fill up with premium.

 

I get 26mpg on my 95 se 5spd. I do 50%city/50% highway. Have always put regular gas (87octane). No CEL light, but did replace my knock sensor once.
Max
ps 182000 miles and counting

 

I get around 32 MPG in the turbo Maxima if I stay out of the gas and off entrance ramps.
I only get 25 out of a 95 Miata type Are-Ruh, and 27mpg out of a 4 cylinder Camry.

 

16-17

 

my odometer stopped working so i have no idea what mpg i get lol.

 

^ deffinately quote worthy.

Ever since i replaced my knock sensor in my auto.... i've gotten 23-20... and i feel like i drive like a grandma.

93 only... 25% city and 75% highway.

 

I get between 28-33mpg, I use 93 octane. But I get well over 40mpg using 87 in my ae92 yota regardless of driving style.

 

I don't see gallons in there anywhere, therefore you fail and infinity it is

I have a 96 GXE with 254,000 miles on it and i get about 430 miles per tank. I drive about 110 miles each day round trip to work and home. I will not get rid of my car because it gets great mileage and it still runs great with little headaches.

 

I can get as little as 16 if I drive like a moron and as much as 31 or 32 if my tank is 100% highway.

 

 

Usually around 425 to 440 per tank, but I know drive my 98 Altima, I see 33-36 in it.

 

25-30 do about 85mph usually...i drive on highway about 90% of the time, i use regular and throw in a S.T.P. gas treatment no problems just usual wear an tear

 

I've been driving my Max for four years with on regular octane with no engine side effects or pinging. My brother had a Maxima that he drove on regular for 300,000 miles with no side effects.

If you want to be on the safe side re: reducing any potential knock, get a repair manual and an ohm-meter and make sure you Throttle Position Sensor is set to the right resistance. (This was easy on my car, I just needed an ohm-meter and a screw-driver, took me 10 minutes.) My TPS was set a little high, which I believe sets your engine base timing which advances from there with your RPM. Once I set it to factory specs, my car ran smoother and my gas mileage improved.

 

We are out of High test in the Atlanta area!! I'm using regular for the first time!!

 

95 Se. average 22-24 30% city 70% highway with a fair amount of stop n go freeway traffic.
