Hi guys

have owned my new NM35 for a week now and tonight i filled it with fuel for the first time.

the gauge was a fraction over the bottom E line and it only took 53 litres.

i thought at the time how odd that was and paid - after starting the car i was waiting for the level to rise

but it never went past 3/4 i then thought maybe i didnt fill it properly and it may have just clicked off prematurely

so i pulled into the next servo to top it up and i couldnt get more than half a litre into it.

i SMS's the previous owner and they have explained that they have never experienced it.

so either the gauge is way wrong or the tank has had lapand surgery.

im not retarded and know how to fill a car with fuel

anyone experienced this?

I have similar issues where the light is on and still a quarter tank left. If I switch off the car and back on, it will display 1/4 again. Its just the sender contacts wearing I guessed, although they looked fine when I installed the Tomei pump.

there is a fuel light?

maybe im best to keep driving until i see it turn on. i have got it to E once already this week and didnt notice a light.

I've done the unthinkable and ran the car for another 80 kms after the fuel usage screen tells me there is -- kms left. I then filled up the entire tank to see how much it will take. 76 liters, scouts honour. She still had a few more kms out of her :P

I think Nissan gives you an incredible amount of reserve to drive a lot further lol.

And I agree with the gauge as well, my warning light goes on nowhere near the E.

im taking it away this weekend for a country run. 480kms in one direction and then home a few days later.

prob not a good time to experiment when im out of the city.

when im home after i plan to drive it until the light comes on. cos i think my gauge is just rooted. hopefully the light is more accurate.

Oh and when I did that 80km stretch, the needle didnt move a single micrometer and was well below the E level. At that point I decided not to risk it lol.

Mine is just the same, nothing like driving along the F3 with the fuel light on and the needle past Empty and waiting for the cough and splutter lol

The few times I have done it she has made it through to a servo on pennant hill road, so there must be a nice little reserve of fuel.

Just remember that when the light comes on, the needle is nowhere near the real empty mark.

You can see a little "rest" for the needle about half way between the tip and the base, when the needle is resting on this (it will be below the "E" mark) you should be getting concerned.

Oh, and I am with Eugene on this one. You should be able to get ~100kms after the light has come on... or possibly more if cruising :blink:

There was a thread recently about this. Basically my guage does weird things all the time.

Lately its been slowly dropping to 1/2 way then races down to 1/4 very quickly and then slows down again around the 1/4 mark and seems to fluctuate up and down from that point on. sometimes it jumps almost 1/4 up during a longer drive somewhere...kinda cool watching the fuel guage go the wrong way but unfortunately it obviously doesn't work that way in practise.

The tank should hold 78L or so. My empty light comes on around 60-65L so yes there is still a fair bit of reserve even when the light is on.

Thats exactly what mine does. When I was removing the pump, I saw a reason for this, the tank is actually 2 tanks because of the tunnel, and there is only a small hose linking them together which takes time to equalize.

Well I'm away interstate with the car at the moment, was full when I left and have nearly travelled 600kms the gauge is dead empty and touching the needle, I'm still waiting for the fuel light to come on. Be interesting to see if it does, I will have to refill tomoz to drive home so my little test won't get to be complete but I'm tipping I should get to at least 700 kms before needing to fill.

Will re test over the next full tank.

As previously mentioned in this thread the light *should* come on when the system estimates there is a range of 50km's left in the tank.

If you have a pop-up information screen you can check the current range which is based on the average usage.

If your right on empty the light should have already come on, perhaps the bulb is blown or something? Or your fuel tank is way out and there is still over 50km's left in the tank. However if you have traveled 600kms you would be on empty so something is up, might be worth getting it checked out.

I've got the japanese nav disc in mine and the nice lady tells me in japanese when it's time to consider a fuel stop.

Well I filled up and drove home today, by this stage the car had travelled 620kms and it only took 64 litres so I'm estimating that I could have probably travelled another 100kms until the light came on, pretty happy with the economy obviously most of that is highway driving but I had a full boot and 4 adults in the car and was also giving it the odd squirt in boost

Yours is extremely fuel efficient then, perhaps that is due to mine having the V35 Powerduct which allows more air flow into the airbox.

I can't wait to finally get the ECU remapped for fuel efficiency, be interesting to see how much I can get out of a tank then.

Highway travel, everyone should be getting 10L/100 or better.

Maybe it has more to do with your right foot control than anything Steve (I too have a Powerduct, a CAI into the bottom of the airbox and a fisher intake, so I don't think you can realistically blame the "extra air" for your sub-par fuel economy - or am I missing the sarcasm? :( )

...well I would like to think the power duct was an effective add-on, given it's high price ;)

yes, yes, once again Nissan bends another person over :D

    • I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.  
    • Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days
    • It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
    • I assume clearances were all a-okay?
    • Shock tower brace is in +5Kw....LOL
