I'm new to this site, so this question may have already been asked (I just didn't see it). I have an 02 X with about 145000 miles on it. It gets about 16.3 mpg, which translates to $60 every 2 to 3 days. Is there a way to get better gas mileage? Any bolt ons or additives?

CAI, new headers, new exhaust, switch everything to synthetic. each adds just a little bit more... NO THROTTLE BODY SPACERS!

Do these add enough gas mileage to off set the cost? And where can I find these parts?:fantastic:

that depends on you as a driver. being a little softer on the skinny pedal, coupled with these things, yeah it could be worth it. each thing also gives you just a little more horsepower too. on what i think tends to be a slightly weak engine.

and the internet is where a tend to blow my money.

Thanks. My wife drives it the most. Unfortunatly she drives too far. Roughly 3500 miles every three weeks.

don't drive faster than 55mph, use cruise control on freeways, gentle acceleration, tire pressure. i have 2006 i get 20mpg average. on freeway at 50mph i can do 25 mpg. mileage deteriorates rapidly as u drive faster.

i have a 00 and the cruise when used gets worst mpg.... i also get better mpg when i do around 70. i can get up to 28 and thats like i said a 2000 with no mods to the motor...... i can get 350-400 miles out of a tank

this morning i was getting 30mpg..... i now watch the scanguage all the time to see the best i can get.....

That's a bunch of BS. No one gets 30 mpg in an X. Maybe for 20 feet while coasting downhill, but not for thousands of miles.

My '06 XOR 4x4 is rated at 16 City and 21 highway - this information was on the Window Sticker when I purchased the truck. My experience has been in the 15-16 mpg range with a best of 18.

My old truck was an '01 2wd, and it got between 16-17 with a best of 19.

oooh thats a hefty call out on jason.... but i can get like 330 on a tank. i need a scan gauge...

no bullshit unless the scanguage is lying to me i am getting 30mpg at some points and i can hold it for a while!!!!!
i have no reason to lie......

also when you just coast it shows alot more than that i have had it up to 120 befor i get to a complete stop.... the 30 mpg is the instant mpg but when i look at the average it is in the low to mid 20's....it depends on how i drive..... like i said just a min ago i have no reason to lie there are times when i get great mpg like that then there are days that i get crappy mpg...... i dont know i guess i have a one of a kind X......LOL

I didn't realize that you were talking about "instant" MPG. Just curious, what is your long-term (1,000+ miles) MPG?

oooh thats a hefty call out on jason.... but i can get like 330 on a tank. i need a scan gauge...

me too. i finally let the fuel light come on, and my DTE was down to 15 miles. i got 331 miles on the tank, my best ever.

I've got an '01 Xterra 4x4 & have never gotten better than 22 mpg or so. That would be on long road trips. I just recently did a 3,000 mile road trip & did no better than 19 mpg. That was through Colorado & the mountains sucked up a lot of gas.

I have found wind resistance to be the biggest mpg killer. I typically have a Yakima basket on top & that loses me around 3 mpg. Speed also hurts mpg but I rarely have the patience to do 60-65 so I lose out there.

My advice is to remove anything that drags in the wind & keep the speed down.

yes i got an average of about 22-25 mpg on my tril to amarillo monday the only time i get good gas milage is when my girl drives and i dont know how she dose it but the guage will read 29-30 for a while..... but she has a light foot which helps alot i have found out..... im dreading the drive back cause im affriad that i will be heading aginst the wind not with it like the drive down so it will cost alot more....
:thumbsdown-big:
around town up here i have been getting real bad milage do to the hills and the dips that are everywhere....

I've have gotten 24mpg on my 06' during highway driving with a little more than 400 miles to the tank

rltilley.... do you get worse fuel milage up in the here? i know the air is thiner but shouldnt th o2 sensors say hey theres less unburned air so lets lean out the fuel a bit?

rltilley.... do you get worse fuel milage up in the here? i know the air is thiner but shouldnt th o2 sensors say hey theres less unburned air so lets lean out the fuel a bit?

That may be the case. It sure felt like the engine was laboring when I was climbing some of those passes. My '01 Xterra doesn't have one of the stongest engines around though so maybe that's all it could do at any elevation.

I think it was mainly the constant grades that killed my mileage on that trip rather than the elevation though.

i know what you mean about the grade cause i went to fritch, tx today and the highway is nothing but up and down up and down.... LOL so bad that when you are at the top of the hill you have cell coverage and at the bottom you loose coverage..... LOL

We'll probably be getting an '04 ~ does anybody know what kind of MPGs we can expect with that?

Thanks!
:D

Oh wow. 330 Miles to the tank?! Im gettin 220...maybe. Only around town though. Translates to bout 14 miles to the gallon.

-03 5 speed Manual.

My tires are shot too...So im thinking that might have somethin to do with it.
Hopefully.:biggrin:

:D

depending on how you drive, and how well you keep track of tire pressure, etc. you can expect anywhere between 14mpg and 18mpg in a 2004 xterra.

At higher altitudes, the lower ambient air pressure lowers the effective compression and engine efficiency. Even though the mixture is compensated, you'd need a supercharger to regain the lost mass of air and fuel. rltilley.... do you get worse fuel milage up in the here? i know the air is thiner but shouldnt th o2 sensors say hey theres less unburned air so lets lean out the fuel a bit?

I can get 24 mpg on the highway if I keep speed down to 60 mph, level highway, no headwind. This is with a 4wd 2001 with V6 and 31" tires. I have checked my speedo calibration.

Don't go by scanguage or computer. Us the old fill-up to fill-up and check mileage method to get a more accurate representation of YOUR gas mileage. Everyone drives a little different and that is the best tried and true method.

Right at 19mpg on a trip. "07 auto S model.

you guys get amazing mileage compared to me. my 02 v6 5 spd 4x4 gets like 13 to 16 in town, with 18 being my highest at 65mph across washington state. i only get about 240-260 per tank.

THATS HOW MINE WAS FOR A WHILE, BUT NOT SO MUCH ANYMORE
IM THE SAME AS YOU

That sounds about right to me... unfortunately.

Yeah, I get really really bad mileage too but I also tend to drive crazy when others go too slow. I miss California driving. Insanity is expected

i can beleive that. i have good tires and a high flow filter. and i can get up to 28 29. its all how you drive and what you do to your engine.

im right with you guys...i have only seen about 19mpg at the highest, usually its right around 14-15 unfortunatley. but the trade off of driving my X is good enough for me versus driving something else!

I didn't realize that you were talking about "instant" MPG. Just curious, what is your long-term (1,000+ miles) MPG?

For those of you with MPG in the 20s and 30s: Forget the Scangauge crap. What is your long-term MPG when measured by the "fill-up to fill-up" method over the course of 1,000 or more miles?

I gots to get meself one of those scanguage thingys if it's gonna double my gas mileage LOL. , 14 in town, 17 highway but it's very hilly around here

I just bought a new 2008 Xterra X 2WD and got about 18.1 MPG on my first full tank of gas. This is in 85% stop-and-go, bumper-to-bumper traffic, so I'm actually quite pleased. :)

i can beleive that. i have good tires and a high flow filter. and i can get up to 28 29. its all how you drive and what you do to your engine.

doubt it..........................

i dont really know now, i can get the scanguage to sit at high mpg some days and then others not so well....... i think im going to send the guage back and get it updated with there new x-guage software......

theres an update?
whats it update?

ricer give me a call when you get off of work...... LOL

My Cell I Broked
You Gotta Call The House
Do You Have The #?

Caps Lock Pwnz Me

I agree. I have a 07 Xterra (6-Speed) with only 12K on it. I have experimented with different types of driving and all types of fuel. Regardless of how I drive, I've yet to see better than 17MPG. I just switched to synthetic oil, we'll see if that helps any.

That's a bunch of BS. No one gets 30 mpg in an X. Maybe for 20 feet while coasting downhill, but not for thousands of miles.

My '06 XOR 4x4 is rated at 16 City and 21 highway - this information was on the Window Sticker when I purchased the truck. My experience has been in the 15-16 mpg range with a best of 18.

My old truck was an '01 2wd, and it got between 16-17 with a best of 19.

I just did my first tank of gas in my 01 .
After reading some tips i made sure i never went over 2500 rpms.
Slower starts and let it pick up to speed at a slow rate.

Looks like i am only getting around 230 miles to a tank or so.

I filled up when the gage read just under a 1/4 and drove it till it hit the same mark i went 210 miles i am thinking i must have another 20 left in the tank before its out.
So i am at around 230 a tank give or take a few miles.
That puts me at 13.5 mpg not so good driving around town no highway.

01 4x4 6

been thinking about adding a K&N Air Filter, knowing that can give you a little better throttle response etc, but would that in turn hurt gas mpg..

I SWEAR!

I put flowmaster and K&N on mine, and I do about 22 in town. 24 -26 Hwy. No joke!

anybody that says they get more than 20mpg in a X, i dont care what year,how slow you drive, what type of mods you've done... are full of crap...And i dont mean this to call anyone liars..i just dont belive it....i know its my opinion to believe it or not so i dont want to start any arguements but mid 20's come on now who you trying to fool...

Well, Chantale may have that advantage because her X is 2wd....not 4x4 so she has less weight than a normal 4x4 would with the powertrain and tcase on it thus adding more weight.

Well said Stevin! lol

Well said Stevin! lol

Haha thanks! :informatiker-big:

i wasnt reffering specifically to her i did keep that in mind but still mid 20's??? anyways im just glad gas prices are coming down for those of us that dont get 20mpg+...

Right at 19mpg on a trip. "07 auto S model.

I have an 07 also.
19 is right on!
New tires and good gas.
Have about 16,500 miles on it.

I don't know what to tell you, but I get 16-18 in town an 22-24 on the highway on a trip. I have an 06 4x4 totally stock (except for custom paint, lol) and I drive like grandma, lol, right at the speed limit. It's been that way from day 1. I have just over 17k on it now. That's going by the old school way of fill up to fill up.

(and always with super unleaded, which gives me 3-4mpg more than the cheap stuff)

Last year on the trip to SEMA we averaged 22mpg there and back (we only had a couple 24's and a couple 20's (in to mountains) but over all 22mpg.

I have no reason to lie, lol.

You want bad mpg, try driving a 65 cadi hearse, Im lucky to get 8mpg, lol.

i might have to give super unleaded a shot since the prices of gas are going down..im going up to VA this weekend its not all highway but its not all city either..But ive tried the 55 vs 70 and taking off slow and still got the same crappy gas mileage...

Yep, give it a shot, you have nothing to loose, I mean it's like 3-4 bucks more at fillup and if you get a few more miles per gallon it's more than worth it, lol (jusy do the math). I only run super in all my cars and it works with all on them. I save money by running the better gas, lol, (wacky isn't it, lol).

yea it is wacky..but 3-4 more bucks at fill up is worth the extra mpg gained i think..its ok to run super if my x isnt super charged?

I personally think it's better, but everybody has their own opinion on that one, lol. All it is, is a smoother burning fuel. Some say it's a waste of money, but it works for me and coming from a racing background, better fuel = more power and less wear and on the motor. All pluses to me, lol.

thanks creepy i will give super a shot this weekend and repost on sunday with results if they are better or not....

Cool, I'm really curious now, lol.

My Xterra is getting 17 mpg according to the ScanGauge. That's with all the mods/weight/stuff on top. That's not too bad. I'm not a crazy driver. I drive 70 on the highway..but the speed limit is 65, so that's not even that crazy either lol ; but in town I'm light on the pedal and let it get to speed at my own pace. I'm not interested in the old lady beside me at the light gunning it to beat me off the line. My rig isn't built for speed, and I'm not trying to impress anyone with a 0-60 time ;) Let her waste her own gas from stop light to stop light. I also use 93 octane (super unleaded) at the pump in all of my rigs.

Cool, I'm really curious now, lol.

ok i forgot to post back Sunday...but i got 18.5 mpg...That was driving conservatively, but unfortuanatly where i live its mostly city roads with stop lights. not stop and go traffic, and some highway driving...

That's pretty good. Premium does help the engine run a little better...not much, but at least it's getting you some good numbers. I think a lot of it comes from keeping it conservative (below 2500 rpm, no fast starts at lights, etc..)

I have 11,000 miles on my stock '08 4wd Xterra automatic. In the dirt? 15mpg. 80+ on the 405 in the SLOW LANE because of all the crazys? 19mpg. I got over 20 a few tanks. BTW, Super in SoCal is 91 octane.

Just got back (well, sunday), from Dove Canyon/ Red Rock area in Kern County, CA.
MUD MUD MUD!!! Drove from OC to Newhall (near Magic Mountan in north LA County) then 90 miles to Mojave. Another 12 miles turned off in the dirt almost all 2wd. Only 4 miles in LOW. Filled up in Mojave then Newhall. 185 miles/ 12 gallons. 15.4 mpg worst ever!! I did bring back 100+lbs of mud on it though.

Sorry, Brothers and Sisters. Left camera at home with the Motorola raidos on the counter with the bag full of food. Yesterday I washed most of the mud off at apartment car wash. Looked like a 20 foot tall dog took a dump all over the place. Dont worry, I cleaned most of it up. It took more time to wash the ground off than my X. Tread Lightly. Off Road and in parking lots!
My friend from Vegas Just bought a new Hummer H3. But the baby would rather have a motorhome than another 4WD. Other Weenie friend has a 07 X he too drove in the motorhome. After all it was a chilly 44 degeres :kalt-big:
BTW a 1987 Winnebago gets 6mpg HAHA

I get about 17 to 19 MPG, using fill and figure system. 94 octane in a 02 v6 SC 5 speed, dead stock no toys. I tend to run low rpms when buzzing around town so that may help. I have noticed I am closer to 17 with cheap low octane gas and much better off with high. Brand seems to make a difference too.

i can constently get 22-22.5 all the time now with a best off 24, but idrive very easy and never over 60mph... as im not ever in a hurry to get no where it doesnt bother me, and i usually drop it into nutreul coming off the highways on the long exit ramps.... maintaining your air pressure in the tires is a big part on fuel milage too

Wanted to do several tests before posting, but with no mods other than K & N Air Filter I have been getting between 18-20 mpg ... on my last full tank test I got 20. WOOT!

Does anyone happen to know? i have an 03 xterra SE-SC... Does the supercharger add or decrease my gas mileage and is there anywy that i can crank out some more power out of it?

..supercharger.. more power..

A supercharger sucks up some power just to spin it so I'm going to say it doesn't help mpg. However depending on your use of the X, the additional hp added by the supercharger could give you a mpg boost over an underpowered truck that has to use more throttle to keep up.

I'm guessing though that most people with superchargers aren't hypermilers because there are just times when you have to bury your foot and put a smile on your face listening to that supercharger sound.

Supercharged cars and trucks can be very efficient and very good on mpg....Forced induction (whether supercharger or turbocharger) is efficient because its a passive system.

In other words it does not add any power, until engaged which occurs at WOT (wide open throttle, kind of like passing gear in a normal car).

Neither a supercharger, nor a turbo provide a general increase in power across the range of acceleration, they only provide a short burst of power at total acceleration...which, if you stay in that band constantly...then yes, your MPG is certainly going to suffer greatly.

so why is it efficient? When you run 2 Xterras side by side (one N/A and one SC), it's the same stresses on the engine, etc....but if you engage the supercharge on the one, then it becomes a different animal..different stresses, different behavior, different mpg...but again, it's a passive system (meaning YOU have to engage it by wide open throttle). Unless you modify the boost bypass valve, you can have very good control over your mpg in a supercharged engine....and get just as good mpg as the rest of us that don't have a supercharger.

More power? Sure, you can do many things to a supercharger to increase power. Smaller pulley, port and polish, etc...but on these trucks...not many people do those types of things. The Eaton supercharger on your Nissan isn't good for that much of a horsepower gain in stock form...but like I said, a smaller pulley will actually wake it up quite a bit. I have no idea where you can get that stuff for the Xterra...but I'm sure it's possible.

hmm thats kinda weird u guys are getting 15-16mpg in yur x's. i can only go about 250 miles on full tank before i have to filler up again at the E line. what am i doing wrong? is it my m/t's i roll around in the city limits? :(

The MTs certainly won't help. Generally speaking the more noise a tire makes the more gas is needed to turn them.

because more noise = more resistance =)

I find that I am getting similar mileage that I did in my '88 3.0L Toyota 4x4..a little over 400 Kilometers a tank. I do about 220 Km's a week to work and back, which drops me to about half a tank. Considering that my X is substantially heavier than my 'yota was, I am quite pleased that my fuel consumption isn't higher. (the slightly bigger and more modern engine makes up for the weight difference, I imagine).

..i can only go about 250 miles on full tank before i have to filler up again at the E line. what am i doing wrong?..

What sort of driver are you? When a light turns green are you the first off the line? Do you race up to red lights and then brake hard? When driving around the city about what rpm range to you usually cruise in?

Does your X need a servicing?

Maybe check out some of the hypermiling websites and see what they are doing to increase their mpg's.

I'm typically seeing around 280 or so on average before I have to fill up..that's in the city...on the highway it's around 300-310..and that's when the light comes on...so I don't know...that seems a little off. Like Fzzt said...check out some sites and make sure your Xterra is up on all of its services....that 280 and 310 miles I'm getting is adjusted for the difference in tire size through the scan gauge, and it's with the mods and extra weight...so I'm still thinking mine isn't too bad considering.
