I'm not sure if this is a fuel guage cluster problem since I've been seeing some threads about people having gas issues with their g35. I have an 05 g35x.

Before the pic was taken i had at least half a tank I just filled up. Driving home casually about 40-45mph ac was on on the lowest speed setting and on 65. Literally 7 minutes later my gas dropped down dramatically pic below. Is that normal? Or is that a inaccurate reading from the fuel guage?


THIS WAS LITERALLY HALF A TANK 7 MINUTES AGO AFTER TAKING THIS PIC. I WASN'T EVEN GUNNING IT.

 

They sure did!

Consider that those who sell cars for a living are usually able to outsmart unsuspecting occasional buyers.

If the deal sounds too good to be true it usually is.

Be prepared to spend $$$$ to get everything working otherwise sell/trade it in for a new one that comes with all new parts and a warranty.

BTW a fuel gauge is not really necessary.
Fill up, set odometer to zero, drive 250 miles and fill up again.

Good luck

It might be a fuel sending unit malfunction. or you may be driving a but more spirited than you think! lol

 

The x is a gas guzzler city driving it's more a highway cruiser with the factory fuel maps. My 04 never saw past 12.3mpg until I started driving the highway more often and now it's 16.9 on the nav. Cruising at 55 Max's out the mpg meter at 30 and and anything faster as long as I use cruise control keeps it around 20 but people say it's not accurate

 

Fuel gauges can be finicky.

I'm not sure what this other guy is saying about fuel gauges not being necessary... he sounds like a complete idiot.

But beyond that try filling it to full and see how fast the gas drops based on how many miles you drive.

 

Sounds like an idiot? Bro I drove a car with a completely broken fuel guage for 5 years and never once ran out of gas. It's not necessary; it's convenient, but not necessary..that is assuming that you're smarter than simple math.

 

Only works if you always drive your own car and know your own driving habits and consciously keep track or just play it very conservative.

 

Ah, I see. So you're under the impression that he's driving someone else's car? And habitually drives like someone else? Cool. Makes sense.

 

Nope, but it also depends where you live and how the weather affects your gas mileage.
I know that the mileage in my G fluctuates from 13.1-18.6 average (mostly city) based on the weather and how much traffic I get stuck in.
Therefore if I didn't have a gas gauge I would need to fill up every ~200mi to be safe.

 

So, you're assuming he drives in a multitude of terrains and unpredictable weather conditions on an extremely regular basis? Like his local town just mutates into/out of hills, valleys, and it can snow, rain, be sunny, etc all in the same day? I'm failing to see how this is hard to get a handle on..

 

You fail to see anything really.
I live in Miami and there are no hills or valleys, but there is varying traffic and uncertain weather.
These things affect gas mileage, so like I said you would have to be conservative about fill up mileage so you didn't get stuck. And if your car did develop a mechanical/powertrain problem at any point in time, you wouldn't know where you stood.

 

Did you look under your car to confirm you dont have a leak? Some fuel thiefs will punch a hole in your tank with a screwdriver and drain the fuel into a bucket.
