INCREDIBLE FUEL STILL DROP EVEN THOU DIDN'T DRIVE

[MadMatty]

I was on medical leave for 2 weeks and the day before i went on medical leave I had top up my car to full. Amazingly even though I did not even drive the car for nearly a week, I only went down to warm up and keep the battery active by running for maximum 5 minutes each day. My fuel gauge indicate that the petrol has already dropped down to nearly the half way point between the full and 3/4 mark.  Now that I am back driving the car, my FC already at 1/2 tank even thou my mileage travel was less then 150Km. I know that Latio FC is notorious but this really is ridiculous.

Most probably, its the fuel sensor problem. Mine has its mind on its own, after refilling it appear full. Come, next morning, the fuel indicator appear at 1/2 mark even though I had travelled only 5km.

Drive till the orange light comes on then go refill and see how much is being put into the tank to know how mucch is used, I get to fill only about 35 litres when my orange indicator comes on. Another possibility is evaporation, especially when parked in open car park.

Well my average is also the same, light comes up once fuel level hits below 35 ltr, this time I only managed to clock 340km and the fuel indicator light came up. Went to top up and true enough I pump in about 36 ltr there after.

I was hoping this would be a one off occurrence perhaps due to evaporation of fuel but that cannot really explain the vast difference. Further more my car park is a multi storey one so it is shaded from the direct heat of the sun. So after my last top top the same thing is happening again. Already at the 1/2 way mark even though mileage showed only 150km traveled.

I intend to bring in the car to TCM next week and ask them what the hell is actually wrong. A car doesn't just consumed so much overnight. Before I could still hit average 220km before hitting the half way point.

I know that Nissan vehicles are not exactly known to be economical but this is really stretching the fact a bit too far.

Err isn't it common knowledge gasoline is highly evaporative ?

you can try filling gasoline in a 1.5litre coca cola bottle full and close it tight,
then leave it in a dark cool place, for 2weeks. 2 weeks later 1.5litre become 1litre.
no joke man .

Don't jump, sometimes it's the way you refill your tankful. When I top up my petrol on my own, I lock the pump at the first stop so that the flow into the tank is slower. you'll normally put a little more into the tank. Estimate your FC only after a few tankful and not based on 1. Highly inaccurate. I'm getting an average of 12.7 throughtout my last 5 years of ownership. Quite a bit of short trips.

well i did take this in but honestly to lose at 5 to 6 liters off due to evaporation is just a little too far fetch for anyone to accept...as I had elaborated earlier, i have already refilled the tank since the last and was hoping it was a one off occurrence. But doesn't seems to be the case cos by the time my fuel indicator hit the 3/4 mark, the mileage only read 80km traveled. Half way mark only read 150km.

Since day one when I got this car, my mileage has never been on the high side, the most 400km before light up indicator with about 220km at the half way mark. But to drop so suddenly, something is not right. My intention is to go for one more round of monitoring before making my assessment and bringing it in to TCM to check.

Well I have been using this car for the last 3 years and it has been returning the same set of figures. 400Km give and take 10km the fuel indicator will come on and then I will drive it for another 20km or so before topping up. Each time I top up its about 37 to 38 liters. So I reckon that its about 35 liters or rather the fuel light up indicator is made to light up after 35 liters used. Based on this, my FC is only about 11.5km/liter average.

No harm sending to TCM to check. Don't expect much from them, my indicator came on around 420km most of the time. I'm driving 4AT 16"rim 205/55/16 tyres. The same for the last 5 years and nothing much have changed over the FC, running on 10W-30 engine oil.

[d.titan]

my FC is constant at 350km for $50, abt 23l (caltax 98)
on 16" , using 10/40 EO (amsoil)
hope this info helps

wow u running on 205 width...mine is 16"R55/185 only...today just went to top up...low fuel indicator light up at 370km (and petrol just increase by another 3 cents ) travel 15km before topping total of 37.5 liters to full tank. Will monitored for this last round before sending in to TCM as also due for 60K service. Just wondering whether problem could be due to ECU because during those two weeks on medical leave, I discovered battery strength was very weak due to lack of running and recharging.

How old is your battery? I've recently changed my battery and I notice a difference the moment I take off at the traffic junction with the new battery that there is lesser load on the engine. You may be right about the battery part. If your battery is anywhere near 2 years old, you might want to consider changing it. I swop out my old amaron after 2.5 years and most of my earlier batteries lasted less than 1.5 years.

I remembered I change it exactly one year ago before it turned 2 years...I actually hooked my Black Vue recorder as a car surveillance unit too but I have paid extra to installed Magix Power which is supposed to ensure that it does not drain the battery.

Was looking at that camera, how much did you pay for it, care to PM me.
