My FC getting worse.......help!!

[gh05tss]

Ok..did the test and the result is out for me.

Pump SGD20 of Ron95 - 9.24L when my light up, just now my light turn up at 97.3km, so this give me - 10.5km/L

Is this bad?

You shld be pumping at least 10L to make good judgement

[gh05tss]

Cos i pump accordingly to $amount...SGD20, SGD50...by Liters will be better?

we measure mileage by liter consumed mah, no logic to measure by $ leh...

ok...will try 10L later n see what I get...I shld get 105km b4 the light goes up....

Actually measure by $ is the same as long as you know how many litre  you pumped.  You will then take the distance travelled divide by the number of litre.  Actually, the light lit up also not very accurate one.  Ever encounter that the low fuel light was on, then it went off by itself after a short while (about 2 minutes) while I was on highway.  Then on permanent again. Then I top up near my home. 

At times when I really want to know the FC for that tank, I will do the following:  (though some bro/sis may not like the method and have their own ways)

(1)  Top up to the brink. (Do need to note how many litre was pump in.)
(2)  Travel any distance (be it 3/4 mark, 1/2 mark/ 1/4 mark or even light on).
(3)  Top up to the brink (and take note how many litre pumped in).
(4)   Take distance travel divide by total litre pump in item (3) above.
(Reason:  Topping up to the brink will give a more accurate measurement on how much petrol is used to travel the distance mentioned in item 92) above.)

To get average FC for a few tanks to be more accurate, then repeat the above for a few tanks.  Based on one tank may not be accurate if during that period you happened to be caught in extremely bad jam, did a lot of waiting while engine and air-con on, etc.

What's yr figure now?

Hi guys/gals,

This is my first post.  Only attended meet-up once in the dark at Marina South.
Collected car on 8th Dec/2007, initially with 38km on the oddometer when filling up at the petrol station. After nearly 5 months, have reached 13,810km at the 28th top-up yesterday, 1st May/2008, cumulative total of 1025.77 litres, mainly ExxonMobil Red 5000(95 octane), did try Blue 2000(92 octane, but didn't like the feel), never pumped Green 98 or any Octane 98 before.
Therefore, (13810-38)km divide by 1025.77litres= about 13.463km/litre on average. I drive a yellow Latio hatch 4AT with about 60/40 xpressway/city pattern. Topping-up normally auto-stop, set on slowest notch of nozzle; no forced feeding to brim.
Noticed following:
a) auto-stop at full normally has fuel pointer slightly above "F"',
b) reaches 45 to 50km at "F" mark,
c) car reaches about 120km at quarter mark,
d) reaches about 250km at half mark,
e) reaches about 390 to 400km at three quarters mark,
f) reaches about 470 to 480 when fuel light comes on.


Last 2 tanks averaged 14.1km/l(but alot on expressway...say 70%).
Car now on 5W30 fully synthetic engine oil, changed out at 11k servicing.
Used to drive a Jazz which gave 14 to 15+km/l even after 4-1/2 years.

CHEERS!...uncle susa.

Guys, when the fuel drop to E, how long more can we travel to get into reserve tank? I never get until light up. (safe or not) Scare half way no petrol.

My experience is that the light will lit up before it reaches the E mark.  After the light lit up, some bros have tried going for more than 100 km more.  Myself tested 50 km after light up.  Dare not push too far.  Scarly caught in a bad traffic jam, then jilat liao.

Another 50km-100km? Hmm.. Means end up, when the light shine up, another 50km is no problem?? Feel risky thou

I think it is psychological.  As mentioned, some bros tried beyond 100km.  I tried about 50km.  Better be safe than sorry.  Image the trouble if your car is stopped in the middle of an expressway, not to mention that it will cause inconvenience to others too, especially if this happens during the peak hour.

That's exactly what I meant.  I shall try till it flash and carry on until 50km before I hit to petrol station.

I have tried to drive more than 120km after lights up (530km lights up, pump fuel at 653km).

It was not a good experience though, as I was stuck at PIE when my odo shown 630km, stuck for a good 20 minutes.

The fuel needle is just slightly below the "E". I top up the tank with 41L, meaning still have about 4L in the tank. So by calculation, I could go beyond 700km! 

Nowadays, I pump in at around 600km, try to be safe than be sorry.

A quick calcuation shows that your FC is almost 16km/litre.  Very good leh.

[iagree]

My FC has been dropping from 17 to 14 for my trip from Muar to JB 2nd link petrol stn. Usually i will get that FC rate.
But normal FC in sg shld be abt 13km/l. but recently my FC has dropped to 11.x km/l , kek sim.

FC is impt, i will service my 17km this wkend, with full synthetic oil, hopefully the FC will improve, also, may need to chk the tyres condition n pressure.

In a way, our car petrol is about 45litre?

Latio petrol tank capacity is 45L.  (You can check the catalogue.)

incl or exclude reserve tank? how much is our reserve tank?

45L is total capacity.  The term "reserve" is used rather loosely here.  Doubt there is a physical reserve tank separate from the "main" tank.
