what kind of driving do you do?

i do 95% city driving at the moment giving it a fair workout around my area and get 400-500 as a usual tank

take it out on the highway and watch that open up to >700 in a tank

City and little bit of highway driving

Isnt it about a 75litre tank?

I get 600ish highway driving.

400 seems excessive.

Yeh thats what i thought......

Full = Projected full tank? I would get about 580-600+ city driving all the time. No mods. Doesn't matter how hard I drive it. I have a GT-8.

We discussed it here:

If you get 400KM only then start looking at servicing bits. AFM, Sparks, O2 sensors.

I've done a proper calculation a few times now.

method was fill up car, reset km's. At the next fill up note, how many k's passed and how many litres i put in to get me to full. results are

1) 441km - 53L = 599km's per tank

2) 442km - 51L = 624km's per tank

3) 444km - 54L = 592km's per tank

4) 410km - 50L = 590km's per tank

Based on the above, if the tank size is 72L (pretty sure) I'm getting approx 600km's per tank. (e.g 441/53*72)

If the tank size is more, I get more k's. And thats bumper to bumper Sydney traffic 5 days a week, 1.5hrs each way each day.

Don't look at when the light goes on to fill up or when your needle hits a quarter etc, as these cars and 350z's are notorious for the fuel guage showing crap.

Try the above, gives you a real idea of how many k's you're getting.

good thinking bobby..

now that you mention it, i always fill up at about 1/8 full, and have never realyl taken into account what fuel was left + reserve and how that could contribute to the kms given on a tank

now if only i could be bothered recording / calculating...

:-)

just note it in a message on your phone.

I'm not normally that anal about these things, but my auto coupe had the Nav system which showed fuel consumption etc, and the manual I have now doesn't. The guage on the manual was telling a very different story to what the auto trip computer was showing so I wanted to check for myself. Also if my guage ever fails I know how far i can go :-)

Both the coupe and sedan have an 80L tank capacity.

I took my first long highway drive today filled up my tank, reset the odo..according to the fuel computer...managed an average of 9.2km per L. At the end of the trip it told me I had 490kms left and I had done approximately 260kms...so thats approximately 750kms! :D

My mileage is about similar to yours with the Z33.

LOL goes to show how much you know dude. No one here has managed to fit 80l into their car... ive driven on the light for 80kms and still only managed 72l in - and that was with fuel pissing out the filler.

And you cant say 490 + the estimate - do a real world test :P

I was getting about 520-580 in my coupe and now im down to 450 with a supercharger :(

JK

Every single spec sheet I've ever seen for the V35 specifies an 80L tank. Remember that the fuel light is usually pretty pessimistic, running out of fuel can do all sorts of ugly things to the fuel system so the lights are usually set to come on very early.

Everyone, please quote L/km or L/100km, km per tank is meaningless as everyone has a different idea of when to fill up.

My 250GT does 9L/100km on the open road and 11L/100km round town.

If you filled up with 72L means that there is approx 8L left in your tank dude. No one will ever manage to fill 80L unless you run your car bone dry till its empty.

My quotes were approximates only and based on the assumption that I would be travelling at 9km/L for the remainder of my fuel tank (which is highly unlikely). Technically thats what the fuel computer is used for...telling you approx how many KMS you have done and how many more you have to go.

I will be able to give you a more accurate reading after I fill up again the 2nd time taking into account how many Ls I top up and how many KMs I have travelled.

Can anyone can beat this?- just 4.3 litres left in the tank!

I had the Japanese girl telling me to fill up asap as soon as i turned the car on!post-21850-1205889777_thumb.jpg

Was that on purpose?

I've heard doing that can suck up the sludge in the bottom of your tank! Unless of course you run it dry before every fill.

    • Yep, if you are applying filler it sounds like there is something wrong with the body lol. Safe to assume there is going to be a lot of sanding going on if your still applying fillers.  Picture a perfect bare metal panel, smooth as glass. You lay down your primer, it's perfect. (why are you going to sand it?) You lay down the colour and clear, it's perfect. No sanding at all took place and you've got a perfectly finished panel.  You won't be chasing your tail, sounds like you were prepping to start laying filler. If your happy with the body after the sanding, there is some bare metal exposed and some areas with primer, no issues at all, start laying the filler. You are safe to lay filler on bare metal or primer (of course check your technical data sheet as usual for what your filler is happy to adhere to).  This isn't a 100% correct statement. There is primer that is happy to adhere to smooth bare metal. There are fillers that are happy to adhere to smooth bare metal. Just make sure you're using the right materials for the job.  Typically if you are using filler, you would go primer, colour and clear. I've never seen any instances before where someone has laid colour over body filler (maybe this happens, but I haven't seen it before). So your plan sounds pretty normal to me. 
    • I don't think there's any way someone is push starting this car.. I honestly can barely move it, and moving it and steering it is just flat out not possible. I'm sure it is, but needs a bigger man than me. I have a refurbished starter now. The starter man was quite clear and consise showing me how nothing inside a starter really should contribute to slow cranking, and turned out that for the most part... my starter was entirely fine. Still, some of the wear items were replaced and luckily it didn't show any signs of getting too hot, being unfit for use, etc. Which is 'good'. I also noticed the starter definitely sounded different, which is a bit odd considering nothing should have really changed there.... Removed and refit, and we'll pretend one of the manifold bolts didn't fully tighten up and is only "pretty" tight. GM only wants 18ft/lb anyway. I also found a way to properly get my analog wideband reading very slightly leaner than the serial wideband. There's Greg related reasons for this. The serial output is the absolute source of truth, but it is a total asshole to actually stay connected and needs a laptop. The analog input does not, and works with standalone datalogging. Previously the analog input read slightly richer, but if I am aiming at 12.7 I do not want one of the widebands to be saying 12.7 when the source of truth is 13.0. Now the source of truth will be 12.65 and the Analog Wideband will read 12.7. So when I tune to 12.7 it'll be ever so slightly safer. While messing with all of this and idling extensively I can confirm my car seems to restart better while hot now. I did add an old Skyline battery cable between the head and the body though, though now I really realise I should have chosen the frame. Maybe that's a future job. The internet would have you believe that this is caused by bad grounds. In finding out where my grounds actually were I found out the engine bay battery post actually goes to the engine, as well as a seperate one (from the post) to the body of the car. So now there's a third one making the Grounding Triangle which is now a thing. I also from extensive idling have this graph. Temperature (°C) Voltage (V) 85 1.59 80 1.74 75 1.94 70 2.1 65 2.33 60 2.56 55 2.78 50 2.98 45 3.23 40 3.51 35 3.75 30 4.00   Plotted it looks like this. Which is actually... pretty linear? I have not actually put the formula into HPTuners. I will have to re-engage brain and/or re-engage the people who wanted more data to magically do it for me. Tune should be good for the 30th!
