this week i decided to see how many miles i would hit before going empty. I fulled it up and went.
$42 bucks = 93 at $2.37 cents
and only 230 miles
that s**t sucks
I changed knock sensor
and gas filter.
a little bit local and a little highway and no heavy driving.
Can i get some help
whats going on

 

check your ecu for any codes... check tire pressure ??

 

you're in ny...ny=city driving. Also, are you heavy on the gas? Check air filter, clean tb.

 

have you done/checked the usual that would cause bad fuel economy?

air filter
TB
IACV
tire pressure? (if you low on tire pressure that could be a killer)

check for codes,
plus if your just heavy on the gas from light to light you will burn much more gas.

 

$42 @ 2.37?!

i pay $40 for $2.59

 

do you drive your car WOT all the time lol

 

91 =$2.59 wth? gas prices are cheaper where u are....i wanna be there.

 

see if your o2 sensors are within spec, might be dying and not throwing a code, recheck that Knock sensor to see if its functional all the time. try cleaning the TB, change your air filter. what plugs are you using? do a tuneup if yo havent done so. and run some seafoam of BG through the gas tank and brakebooster.
lastly your injectors might b efaulty.

 

I get 26-28 MPG on 87 octaine every tank

 

Check you tire pressure.
Check your air filter.
Try one of the fuel treatments in your car.
And try some of the other suggestions that other people said.

 

same thing here. nissan doesn't want to hear it... they chalk it up to the colder weather, and the gas additives they put in the gas so it stays good at the gas station. i hate nissan.

 

Nissan is awsome, you want to hate a car company go buy a Ford, you will learn a new meaning of the word hate!

 

why are you feeding the max with 87? you should be giving it 91-93 depending where you are.

 

The owners manual is kinda funny on this. It recommends using 91 but says you can use 87 on one page. On another page it says 87 and even as low as 85. My car runs fine for me on 87, I'm not spending a dime more for fuel.

 

Did you fill it all the way, drive till empty and then refill it again? This way you can see how many gallons you actually used for those miles.

 

Its BUSH's Fault! The max is fine!

 

i love nissan, but hate nissan customer service. they do not know their A$s from their elbow.

 

it is a bush fault
lol

 

87 octaine? Are you trying to destroy your car's engine or do just want to cost yourself a few $$$$ in a couple of years?

Dude, 92 octaine MINIMUM. Running less impacts the engine compartment, and components. You'll have to replace major engine components in a few years if you keep it up.

 

I was getting about 15miles to the gallon on a bad O2 sensor, got my an oil changed (full service) not sure what they do but now I'm getting 18 to the gallon, as soon as I replace my sensor I should see better mileage

 

i find it hard to believe that u squeezed 17.8 gallons in ur tank.

 

New York City driving cant be compared to other peoples mileage when they are in different states, even highway driving in New York is like city driving, stop and go. the majority of people ive seen saying they get 25 mpg are people who live in Florida and Utah and places like that where everything is highway... the majority of people i have seen getting like 17-20 mpg are people who live in the big cities... i have the same issue. i was getting around 13-14 mpg but i also was getting codes for knock sensor and 1 of my 02 sensors.. i changed my front 2 oxygen sensors last week and i have gotten better gas mileage but it still sucks.. only around 16-17mpg. i still have to change my knock sensor next week so hopefully that will make it somewhat better..

 

i squeezed in 17.6 last week

 

1st of all, No you wont. 87 wont hurt anything, It will just cause the timing to be retarded and hence the car wont perform as well as it would with 91+ octane. The ECU goes into a "safe mode" to prevent engine knock.

2nd of all, where did you get this '92 octane minumim' from? Some places around the country only sells 91 octane (Cali), and it's recommended that you put in premium, not required. I fill up with premium every time, but if you're spending most the time on the highway, 87 / 89 wont hurt the car at all, and it will save you a little money.

 

Save you money in the short run, doesn't anything less than 91 burn faster so you need to refuel sooner than if you put a higher octane?

 

I'm in the same boat. I go through gas like it's nothing. Would a b-pipe and muffler with rust holes affect mpg?

 

lower octaine does burn quicker but so little of a diff i doubt that anyone could ever notice

 

hhahahahahaha bush is

 

I dont know about miles per gallon but I have seen 410 miles on one tank

 

You don't know what your talking about if you think 87 octane is going to hurt this engine. You are the one wasting money at the pumps every week. I have been running my car for 3 years, 60K miles, no issues on 87 octane, almost all high speed highway, the thing run great and screems..............

 

it wont hurt it it just wont get max performance out of it and it just isnt worth the chance for me

 

Try filling up on 91 and resetting the ecu and see if it runs any better....if not, stick with the 87

 

I know it might perform a little better, but with gas over $2 a gallon it runs just fine on 87 octane. Its not a race every day driving 75 miles round trip to work, just get me there Max!

 

for highway driving i would consider using 89 or 91 instead of my 93 but then again i expect to get over 200 k outta this car so.......

 

How do you re-set the ECU, I'll try this and see if my gas mileage improves to offset the extra cost.

 

Half of you guys need to learn to spell. It's OCTANE.

 

yes ! its CH3CH2CH2CH2CH2CH2CH2CH3 !

 

wow maxima hunney speaking out......i mean maksima honney

wanna teach me how??

 

not this crap again

 

wat krap, i jast wana learn how to spell
