nowhereboy Posted February 20, 2015 Posted February 20, 2015 Oh dear! I've set off for work this morning in a bit of a hurry and left my cash in the house. It's about a 7 mile drive and pretty congested with traffic. The fuel guage started showing - - - - about two mile into my journey this morning. Got in to work ok but I really don't fancy breaking down on the A1 in rush hour traffic on my way home. I really need to work on my organization skills haha.... Soooo who thinks I'll make it then?

brillomaster Posted February 20, 2015 Posted February 20, 2015 (edited) yep, no problem. I think it starts flashing '----' when you have around 20 miles of range left - and the gauge is hugely inaccurate anyway - I bet when you fill up this evening you can only fit 61 litres in.

JetSet Posted February 20, 2015 Posted February 20, 2015 I once did over 30 miles from ----, took it very easy mind you . Pete 1 Quote
maddog1982 Posted February 20, 2015 Posted February 20, 2015 Mine hit the flashing - - - - filled up and still had 20 litres in the tank Quote
nowhereboy Posted February 20, 2015 Author Posted February 20, 2015 Wow, I know the fuel guage is pretty useless but it's very unnerving driving about when the needle is flat bottom. Looks like I should be ok tho, fingers crossed. Quote
brillomaster Posted February 20, 2015 Posted February 20, 2015 bit of maths is what you need, when you fill up this evening, make a note of how many miles you did and how much you've put in, to work out your actual mpg. then you'll know how far an 80litre tank will take you, and fill up based on mileage. I gave up using the fuel gauge years ago, I know if i'm averaging at least 25mpg, I can do 400 miles on a tank. frequently driving with the fuel gauge saying '----', but have never actually run out of fuel, even when I think i'm pushing it a bit I can still only get 66 litres in = 14 litres still left in the tank! 1 Quote
brillomaster Posted February 20, 2015 Posted February 20, 2015 also with my gauge at least, if theres less than a quarter of a tank, in the first 5 miles after starting the engine the DTE will drop like a stone, but then after 10 or so miles it realises there is actually still plenty of petrol in the tank, and the DTE reading goes up again!

thedon Posted February 20, 2015 Posted February 20, 2015 Mine has around 25 litres remaining and 60 miles+ when I get the --------. As above, I count the miles since the last top-up. Can be entertaining when I don't brim it and have to guess how much is in there plus the amount I've just added. I'm not as brave as brillomaster because I reckon on 360 miles per tank.. only run dry once and luckily that was on my drive at home (which slopes backward). Quote
glrnet Posted February 20, 2015 Posted February 20, 2015 Here's the problem and the fix http://www.350z-uk.com/topic/54763-how-to-fix-the-inaccurate-fuel-gauge-pdf/ Quote
-Bradders- Posted February 20, 2015 Posted February 20, 2015 I done the above, cleaned mine first, it worked fine for about a month, now if i stick a full tank in, after about 50 miles, the gauge drops to half a tank, then within another 10-15 miles it shows under quarter, then it just sits on red and tells me i have 7mls UTE to which i have driven about 50 miles like that lol. then sometimes goes back up to a quarter.. then drops again!?

RobPhoboS Posted February 20, 2015 Posted February 20, 2015 I wanted to do the fix as well, since I can only get around 48ltrs in there, around 250ish miles between fill ups. Obviously the sensors need cleaning or the sender thing replacing. Brad - how hard was it to do ? Quote
-Bradders- Posted February 20, 2015 Posted February 20, 2015 20 minute job easy, come over sunday afternoon we can do it if ya want? Quote
RobPhoboS Posted February 20, 2015 Posted February 20, 2015 20 minute job easy, come over sunday afternoon we can do it if ya want? I'll be in touch ! There's a chance I could be in Surrey visiting family though (as the last few times I was there, I was under the car tinkering away ) Quote
muckyman Posted February 20, 2015 Posted February 20, 2015 20 minute job easy, did you change the O rings when you did yours? If so, where did you get 'em? Nissan? Quote
-Bradders- Posted February 20, 2015 Posted February 20, 2015 Nah, didnt touch them, didnt get fuel on them either! Quote
glrnet Posted February 20, 2015 Posted February 20, 2015 20 minute job easy, did you change the O rings when you did yours? If so, where did you get 'em? Nissan? Got mine from Zmanalex. Mind you wasn't worth the effort really, it was fine for a few weeks and then reverted to pants so I bought a Scanguage II, it's bang on every time. 1 Quote
RobPhoboS Posted February 20, 2015 Posted February 20, 2015 This? http://www.amazon.co.uk/ScanGauge-II-Fuel-Computer-XGauge/dp/B000AAMY86 Quote
glrnet Posted February 20, 2015 Posted February 20, 2015 Yup that's it. Might be worth PM'ing Wasso ref the OBD scanners too as I think they may read fuel consumption and it'll be a much cheaper solution. 1 Quote
muckyman Posted February 20, 2015 Posted February 20, 2015 How does the Scangauge II measure the fuel level if it's the sender that's faulty? Quote
RobPhoboS Posted February 20, 2015 Posted February 20, 2015 (edited) How does the Scangauge II measure the fuel level if it's the sender that's faulty? It doesn't. I presume you enter some data in, like tank size and so on. Check out some videos on youtube. Edited February 20, 2015 by RobPhoboS Quote

Scanguage plugs into the OBD port and then gives you fuel remaining and avg mpg etc. 1 Quote
RobPhoboS Posted February 20, 2015 Posted February 20, 2015 From looking at the videos this is a handy little device. It's on my shopping list now, just have to work out where to have it installed. Quote
glrnet Posted February 20, 2015 Posted February 20, 2015 Mine is on top of the dash next to the A pillar, doesn't sound brilliant but it's right in eyesight when you need it and the cable is easily hidden, I'll take a picture tomorrow if I remember. 1 Quote
