gas mileage?? only getting 230 miles a tank (14 mpg)???

[lucsious]

lol... k will do.

[lucsious]

i drive to work about 15 miles turn the car off, a few hours later run an errand or 2. and then drive 15 miles home. and yes car gets up to temp before i shut it off

[raremotive]

ok, one less thing off the check list... Just FYI fuel likes to burn best at a certain temperature, to low you will experience bad fuel econ. This temperature varies with octane.

[lucsious]

yes but ive had many cars through the winter all different kinds and they always got better miles per tank then what im getting so far.

mezz I know you're quoting Richie, but 7gal is way too much for 350z 'reserve'. If I had to take a guess I would think its about 3 or maybe at most 4 gallons. With that, what the OP should do knowing she has a 20gal tank is fill up and set the tripodometer to 0. When her fuel light comes on again, fill up. At that point, fill up and record the number of gallons filled. This will tell her how many gallons she burned before the light came on, and dividing that number (like you said) into the trip odometer reading will get her gas mileage for that tank. At that point she can estimate how far she has to go until she is actually empty. Example, after driving 250mi, she fills up with 12gallons(when the light comes on)...shortly after the light came on 250/12=20.8mpg for that tank. Knowing she has about 8 gallons left or about 160 miles. So if she were to push her tank to complete empty, she could get 410mi to a tank.

ummm thats actually what I said, a combination of different things, learn to read......bud

didn't quote anyone, i only get about 13-14 gallons in when im on E and it is a 20 gallon tank..... about 7 is as accurate a guess as i can give when its a 20 gallon tank..... i understand reserves are small but to me when its reading empty the rest is reserve.... so if 7 gallons was the reserve then her mileage on approximately 13 gallons was an average of 18 mpgs which is not bad considering highway and city/in town driving combined over the entire period of a tank of fuel.... just went purely from my experience never seen or read anything about the gallons in reserve.

as soon as my gas light comes on which will be tomorrow , i will go fill her up and let you know how many litres i get in. because if the reserve is alot then i dont have to be woried about my mileage anymore..hope i can back you up.

i'm almost certain you'll find out you are finebut let us know, we're interested to hear what the outcome is

So let me get this straight... you don't care what your efficiency is, but you DO care about how often you have to fill up? That doesn't really make sense.

Just calculate your MPG based on miles driven divided by gallons used... that's what matters.

no, she is worried. If we settle this then she can stop worrying. And I agree only calculate your MPG base on miles driven and fuel used.

Just another thing to ask, how is steering? Does it jiggle at all especially 80 mph? If you hold steering wheel straight, does the car go straight or does it veer off to a side slowly? To test, drive on flat roads.

Yes, but the question was to figure if your cooling system was warming up. If it wasn't then it would be your problem.

[lucsious]

yes the sterring is perfect.the fuel light still hasnt come on and im at 200 miles, when i talked to my friend who works at nissan, he said when he had his 350 he got only to about 250 miles a tank, and im getting 230 so im not worried anymore,, just depends where you live, how you drive.. etcthanks for all the help.

[lucsious]

maybe i worded that wrong,what im saying is if hes right about the reserve being alot. then im not using up as much gas as it looks if 7 gallons are left when the gas light comes on then ive only used 13 gallons instead of me thinking ive used 17 or 18 and only got 230 miles

I gas up when the fuel light comes on, and I'd only be able to put 13gal and some change.

Well, you would know at the very first fillup how much fuel goes in.

I dunno, I don't get it.

That's odd - I routinely put in 14 or 15 gallons & I've never had the low fuel warning indicator light up.

As far as mileage that drivers are getting I just put in 14.89 gallons this morning and the trip odometer read 330.3 - my driving is 80-90% highway/interstate.

[lucsious]

there was gas in it already when i got it last week,and havnt filled it up at empty yet.only half and 1/4

[lucsious]

ok filled up today as soon as gas light came on. and was only able to fill it up with 51 litres which equals approximately 13 gallonstherefore if the gas tank holds 20 litres then the reserve has to have the remaining 7 gallons. and my clock calculated 230 again which is roughly 16 mpg im getting still low.. but oh well could be worse.

how do we know for sure its a 20 gallon tank ??

[ldstang50]

Nissan claims it to be 20gallonshttp://www.caranddriver.com/ca....html

I've filled mine up with 17 or 18 gallons on a regular basis, really didnt' care much for the idiot light being on.

[rmezz13]

13 @ 230 ~ 17.7 mpg

which is about what i figured before... regardless 20 gallons or not (which is manufacturer listed) 17.7 or ~18mpg's average is not bad for this car. I would imagine as much as your filling your driving it a lot and in town. Could possibly invest in a new higher volume air filter (K&N for example)

P.S. i can't believe this thread has made it 3 pages....

Yes way to many pages considering it is all over in the search.

You and I know exactly why...

or do you...

[lucsious]

why?

[R350Zz33]

im gonna guess that its because ur female or canadian im leaving more towards canadian lol

[rmezz13]

You and I know exactly why...

or do you...

yeah every time a female enters a predominately male area, they all have something to say! The funny thing is tho, most of these guys wouldn't have the balls to approach her in person.... weird intrawebz is

P.S. only locking it because i feel we've came to a solution (mathematically) and it is straying off topic...
