Bborges, we're not going to win. I stand by my comment, this guy is a douche.

 

Well, at least you got your first sentence right. I apologize if actual research and debate is beyond you. Although, I suppose all brilliant minds present their ideas be concluding that those who oppose them are... "a douche". Unlike Bborges, you have nothing useful to say.

I agree, that they can. And ANYONE who achieves 60 mpg on a country back road, can claim that they do achieve 60 mpg on a country back road, like me.


I don't believe you bought the wrong car, I'm simply implying that the car you drive was not engineered, designed, nor marketed for the purpose of acheiving 30+ mpg. I do not see how this is so crazy to assume, or how by assuming it, I am "INSANE!"


Facts:
1.) Any civic, and any car model, generally speaking, in 2007, does indeed have the capability to exceed posted speed limits.
2.) No where in any of my previous posts or thoughts did I mention anything about speed limits, or driving fast.

Also, about the law. While I am not researched in many other states than my own, I do know that where I live, simply travelling in excess of 60 mph on the highway is not illegal. Actually, unless the word "maximum" is printed clearly on the speed limit sign, nor is travelling in excess of the posted speed limit a crime. But I won't get into the specifics of it here, that's another time and place.


I would like to reiterate:
So don't get so dang defensive, I wasn't saying you bought the wrong car or making any comments about your taste. I didn't request your justifications. Jeez.

I did say:
Maybe this is the "nonsense" that makes me "INSANE!". So allow me to explain:

Normally, someone who has calm driving habbits, such as yourself, who enjoys taking his time while travelling and boasting about gas mileage is more likely to be drawn to a marketing plot for Civic, Sentra, 4 cylinder Camry, or hybrid cars, than the black flash racing the grim reaper through a desert dirt road with "222 HORSEPOWER" splattered across the screen.

You bringing one example of someone, namely yourself, who doesn't fit that pattern doesn't exactly show that there is no pattern.






Please.

 

It's all kewl man, i actually just jumped in when I read that it was NOT possible to achieve 30 mpg when I know I do it all the time on my 2K SE.

And once again, I understand that the term 30mpg has to be used with caution, because it is over a certain period of time and situation (nicely driving on the hwy) not the average for the car lifetime.


And also I am not arguing with the 3-mile example (which also is true, though completely silly) and i totally agree with the overal 3-month calcs.


Now regarding the maxima as my choice, try considering that I want 222HP when I feel like I need it (i never said I dont stretch when I feel like its safe) and I also want the comfort and the mileage when driven accordingly. No Civics could give me that, and even if they could, the taste-factor also weighs in.


It's all kewl... let this thing die then.

 

Agreed on all points here.

 

One last thing though!

If you are wanting to achieve better fuel, here's some rules for you.

Use the same gas over and over from the time you purchase the car, try to always have at least half tank or more at all times! Reason being, when your vehicle is not full, the fuel pump turns on to suck down the fuel. In return when the fuel pump is in motion, it takes a small amount of fuel to turn the fuel pump over! If your tank is full, then it will automatically push the fuel into your engine for you, and will not work other products that aren't needed (ex: fuel pump) So I know how everyone does hate it, but its a proven fact! Plus you won't have to worry about your fuel pump going out more than likely also

Next always have you some good tread and proper inflation at all times!
Always faithfully change your oil every 3-10k miles depending on synthetic or not. This really does play a major factor in performance and gas issues.

Hope this helps

 

Is this confirmed? Can someone else confirm this? I just want to confirm that the fuel pump DOES NOT operate when full tank. I would imagine these new cars have pressurized fuel lines and pumps running all the time. Some older carburated cars did work like you described (gravity/pump fuel lines) but i had the impression these new EFI were based on pressurized fuel lines.

 

I don't know WTF he's talking about. The weight of the fuel alone in the tank is not nearly enough force to pressurize the line to what is it, 51 PSI for the VQ35?

In any case, for those that don't have common sense and would like 'proof', here's a clip from the FSM:



Engine is running == fuel pump on.

 

I HOPE the fuel pump is always on, what if you park on a steep incline or are standing on suck a high incline at a red light ?

BS, fuel pump should always be on, thats why there is a return line to the tank isnt there ?

This is not the stone age, i dont think Nissan would rely on gravity, cmon man

 

VQ30s have return lines, VQ35s are returnless setup.

 

i had a V8 powered (4.6L) lincoln towncar that hit 30mpg on the highway easily. if you dont believe me, ask some crownvic, grandmarquis, towncar owners.. they can all tell you its possible. so i wouldnt be surprised if a v6 3.0 nissan can hit 30mpg also..

 

Thats exactly what i thought as well! And like said before, how many feet above the car would the tank need to be to provide the required pressure? Definately not the case.


I think that is BS!

 

Neither does he.

 

lol well all I know is that when I fill my tank up and drive only 60 miles or so, I can get like 28\29mpg, otherwise its usually 22 on the dot even if i drive on the interstate most of the drive. But I did just get my new engine installed today and got my car back! I'm so happy and I waxed the **** out of it n stuff like that But... my shifter was sticking in all gears sorta so the tech is gonna bleed them and replace brake fluids as well as put synthetic oil also since its brand new =D

I love my maxima~

N8

 

^ thats a bunch of mumbo jumbo right there, its like you just told a whole story in one sentence

 

I just wanted to point out that he said that there is nothing wrong with driving a Maxima that way. He is just saying that someone who drives like that is more likely to be in a Civic or another compact. I don't think he believes that you bought the wrong car.

 

What is "more likely" anyway? Most of my hwy driving is around speed limits (which drives my girl INSANE as well as my friends when I am the one driving) and you'd be surprised how many people with powerful cars drive on the speed limit and how many compact/economy cars drive well above speed limits. you'll only realize this once you drive slower and you notice whos around you.


Two real examples: my sister got a Versa because she liked the design and it was a small car for a girl. She drives that thing so hard she is getting WORSE/EQUAL mileage than me. She bought brand new and I kept telling her to get back to the dealer because something was wrong. She even has the CVT. Finally i realized she is driving it really hard and it was killing the mileage.

My girl is another example: she has a 2004 Sentra and she gets 300 miles on a tank, very similar to me getting 450 miles on my tank. Shes another that drives REALLY hard and those smaller engines when driven hard are pushing harder and consuming more.


they defy your theory of "more likely". They wanted a "small car" but they drive hard. I wanted a FULL SIZE sedan and NOT a compact car and I dont push it hard, at least most of the times.


You guys are forgetting people buy car not merely based on mileage or how they drive, but mostly looks, comfort, performance (i want the V6 torque, which I do fully use when in the right mood) and others.

 

well i'm just telling ya the truth lol. And boy does driving hard get you nothing on the gas mileage scene...

I'm not even to 100 miles yet and I'm almost already just barely above the halfway tank mark That means I'm heading towards a 200 miles for a tank fill :x so well 200/15gal eww well about 13 mpg is what I got on this brand new engine lol I guess I gotta be going a lil easier with this new engine if I ever want to achieve near 20 range.

 

jesus christ you guys hi jacked the **** out of my thread. no biggie keep it goin haha

 

I've gotten 23 mpg on my third gen GXE before, mostly town driving. And this was on bald slightly deflated tires too.

 

Well I got 24 mpg on the highway and I floored it once or twice to 120 mph lol :P Awesome! I can't wait till this engine breaks in even more The way I had been driving it was saying I was gonna get 430 miles to the tank ;x

 

I have made it from where i live to dallas in 4 hours. the trip to dallas was about 320 or so miles. still had a little over a 1/4 tank of gas. of course i used 93 octane for the trip. prolly averaged about 26 mpg.

On other long trips, i have gotten up to 30 mpg doin 70 down the highway

 

I got 26 once, but my average is 22 with a lot of city driving

 

My last tank got me 25.26 I guess I'm not using the AC as much

 

It's not MY theory. I was trying to clarify what he was saying. I do agree with you. I was just pointing out that he didn't bash your choice in what car you bought.(I've seen plenty of Civic drivers driving like complete maniacs.) I drive around the speed limit myself and I have seen things like you have described.

Btw. When I tried to clarify what he was saying there was no second page showing up on my computer. Apparently the comment was VERY late. o_O

 

mpg can be gotten that high going downhill for sure

 

Really original. You just forgot to mention that for every downhill, there will be a uphill.


This rule for newbies is a PIA because every now and then you see these kinda posts... you can tell they are only trying to bump post count.

 

most of mine is in the city. I drive 4.5 miles to work on city streets. I'm averaging 22.9 mpg. 5.5 gen with 113K miles

 

Aww not bad and good lookin' max you got there! I want to bump up my hp and torque! Anyone wanna suggest anything for a brand new engine? lol Maybe a nismo cold air? Would that be any good to get for my car? Please let me know anyone! I could use some links for the cheapest that you guys know of for nismo. Thanks

 

Seems like V6's are notorious for getting bad gas mileage. My 96 Thunderbird ate more fuel than my V8 TPI Camaro. What's the deal.

 

So...you're comparing a VQ30 to a 3.8 to a 350? Best comparison evar.

 

I completely disagree. This soo generic and so far from true. Outside USA you have a whole market of 1 liter engines (4L) and surprisingly enough these small engines are only economical under very certain conditions.


For instance, a modern 2.0 getting 150HP will be more efficient than a 1.0 60HP engine at certain conditions.


It is not much a matter of configuration (4L, V6, VR6, L6, W8, V8, etc) as much as HOW MUCH HP per LITER you get (translates how thermodynamically efficient the engine is) and HOW you DRIVE it.


An old Dodge 2.5 4L engine WILL have worse performance than a VQ 3.5 engine in most highway scenarios. The only scenario the 2.5L will be more efficient is idling (or really heavy traffic) because the standby losses are less compared to a greater displacement.

 

I was just saying that V6's in general seem to get poor mileage. But don't you think it's odd that this camaro gets better mileage than a smaller, less powerful engine?

 

why not ? its al labout how you drive
for the camaro you can cruise at low rpm not working the engine hard at all
but one the small car you really need to get on the accelerator to get going anywhere

i think its possible

 

Yeah, I totally understand. My driving conditions were about the same with both cars and the V6 would always see the gas pump more. The camaro gets about 5mpg better, I think. I've only owned my Maxima for about a month and so far it seems to do really well on gas.

 

i got 23.9 mpg all the way to vegas from salt lake in my SC maxima.

 

I have only had my max for about a month and I am averaging about 22 mpg right now. I drive pretty hard most of the time. I have a problem with accelerating to speed quickly.

Would you guys say you gained or lost mpg when you started modding you maxs(drivin with the same habits of course)? Gettin ready to add a intake, was just wonderin.

 

95 gxe 5spd fed spec. Mileage 151,000:

When I had my stock 15" steelies on, I averaged 27MPG mixed City/Hwy over 3 years. Now that I have 17" 2002 Maxima wheels (ie stylish heavy anchors), I have averaged 25 mixed use. Not bad for a V6 with daily mod aggressive driving IMHO

 

Well said - maybe a million other things, though.

 

I have a 5th gen and i think my tank holds 17 gallons. I dont remember seeing more than 21 mpg....with combo of city and highway.

 

I constantly get 26mpg city driving, that's pretty much all I drive, so i'm assuming i would get well over 30mpg on the highway. I downshift on decelleration every time and hold until idle. Manual and very modded.
