Fuel Consumption

I thought higher grade petrol tends to burn more easily (which means should be higher FC) ???

Thats what i tot so.. but my previous ride drinks 95 most of the time n one tank is around 390. but occassionally i give it v power, one tank can go to 440..

Hmm......interesting.......maybe i should try on my next pump. Too bad i just pumped Esso 5000 full tank this morning.

oh! so different grades really make extra mileage ?? hmmm
but shell 95/98 also claim 1litre diff / 50lits they translate to ~12km extra... for every 600km..? i think. .ya ..

I think it depends on the existing mileage one is having.
Example is a car is having 1L = 12km FC, that means the full tank can go addition 12km more.
Whereas for those FC super good cars (Fit / Jazz), i heard on radio got this guy who claims he can travel another 20-25km more.

haaa.. those many with seats, a/c, spare all out of his car..heee...

This article here is worth reading.

http://www.fuelsaving.info/fuels.htm

Octane numbers are only important when you want to do some racing modifications such as higher pressure, otherwise if the premium fuels uses a denser base of petrol then it may offer slightly more mileage (paragraph 6 of article) but which the economy of it cannot be recovered from the cost of the premium-ness.

The Shell fuelsave could be using the denser base petrol...

my very first full tank went only 330km. I am sure this is terrible FC. but keeping faith that it's because of the run-in.... Or is it??

most ppl here hit at least 400.... ... anyway keep tracking and see if ur manually calculated mileage is the same... it may be a metering problem as it happened to some bros here....

treysha, are you driving forte or koup ?
you super heavy footer ?
do check engine oil if possible.

i'm driving a forte SX (A). Am definitely not a heavy footer. I keep to the speed limit ALL THE TIME. Plus i try to keep the engine rpm to between 2-3k all the time. Only exceeded 3k very few times. But never exceeded 4k.
What should I check with the engine oil? That it is at the right level?

Hello treysha, then its weird.
1.5 weeks old (have you done servicing ?)
For the engine oil, yes please do check and ensure the it is within the level.
Some bros here reported after their servicing, the engine oil was overfilled and their FC was terrible.
So they went back CNC and request them to drain some oil out and the FC is ok now.

Do check yours.

I've not done any servicing yet.
This is worrying me. I will check the engine oil.

Do check and update us please. Have a great day !

That is pretty bad, my typical full tank do at least double your mileage. Do have it check out asap. Hope it's just a nutty meter.

My car is running for its first 1k...Now mileage 200+ km... Is it normal that when i fill up full tank.. the meter shows that 480km to empty. I think they are running on mineral oil.


is it normal?

mine SX (A)... manual calculation gives only 8Km-9.5Km nia....just change to ESSO 5000 from Caltex to test test if its the petrol or what.....

I think that is normal.......mine shows betwenn 400+ to 500+

Nowadays usually show 500+

But not to worry much, i dont think this meter is accurate because the FC will change as you drive and it will affect the readings again.

i very long didnt full tank le leh.. for the past few months got pump $50 then $3 discount.. so the best bargain is to ppump $50 and not more than that.. like that how to full tank sia..

wait leh..... to do full tank, i usually put 45 liters... so wait until petrol price hit $2.25, then u can put 50dollars 2 times......

i also pump in $50 only due to the promo

i find esso better fuel consumption than caltex.. is it because in 1litre of caltex there are few mililitres of techron thats why it takes 1.2 litre of caltex petrol to be comparable to 1litre of esso?

whaaa.... sure? i am esso regular here..but shell in bolehland.. can feel the different..actually... shell seems to give slightly better power/FC..

yeah, noticed the btter power with Shell in JB also...

You guys are right. the engine oil level is about 3-5mm above the F level. Thanks guys!
Do i need to go back to CnC to get some of the oil out?

From Showroom to 7 Month average FC 13.20km a litre.
Now in the 10th Month with Speedo registering 21384km. FC 12.16km a litre. Anyone having same FC dropping ?

Hello treysha, report it to your SE and see what he advices.
It will be best to send the vehicle back to CNC for them to do what is required (and should be free).
Otherwise, another option will be to send to outside workshop to do (of course got to pay).

Anyways, glad that you found what caused the bad FC now.
Do get it rectified and monitor the FC again.

Happy Lunar New Year !

Bro newsman, are you due for the 20k servicing ?
It might be due to 'dirty' engine oil from the last change at 10k servicing.

I also realized my FC fell a little when my mileage hit 10k+ km (almost due for 10k servicing).

Dirty Oil i suspect too.
Last changed 14400km n using Full-Syn n not due till 24400km.

Changed Full-Syn again @ 21384km @ JB 11 Apr n monitoring.

Great Bro, mind sharing how much it costs to change oil @ JB ?
So you still going back CNC for servicing @ 24k mileage ?

shd be quite cheap, buy engine oil and filter from Singapore and change it at JB, RM$50 -RM$100 for the workmanship but beware of those sheepish looking mechanics if you are not familiar with the place. Run if you feel uncomfortable with them.

For car mileage below 10K using minerial oil, the FC is not constant/stable because mechanical parts(whell, pinon...) are not season yet.
Everybody have different driving condition/habit, so it is not accurate to compare FC for Car A & Car B unless we set a driving condition as reference. For example from point A to point B at a constant speed for min 1 hour for the FC to stablelise and take reading (?L/100KM) from the speedometer. I notice my FC from SIN - Ipoh - SIN after refill full tank (2.0L Auto, Brisk silver plug + Hurricane S/Steel filter):
After 10K mileage, change to Fully Syn oil was 7.1L/100KM after crusing for 1hour at 110KM/Hr on N-S high way.
Yesterday night return from Ipoh suprise to notice it drop to 6.5L/100KM under the same condition. Mileage was 18K++ from Ipoh, reached SIN 19,200KM.
I think the best road to do the testing is NS highway from JB to Malaca (about 200KM non stop)since the road are flat.
I only pump Shell 95 in Malaysia from day 1 after collect my car. I always pump full tank when come back, before 3/4tank I go back Ipoh, so did't pump petrol in SIN.

BYO Oil n Filter. 20- 35 mins Labour charge.

Sutera Mall RM18 + Tax = RM19....done my 14400km
Along Jln Scudai abt 7km from ICQ, Back to Back to MAYBANK.
C H Motor RM10....done my 21384

Bro, try to reset the ECU by removing the battery negative lug for 1 to 2 mins.

Later u will suprise when u top up petrol, empty tank shown 500 plus..

And ur per ltrs/100km oso improved..

Has anyone switched from Caltex to Shell FuelSave? Any improvement in terms of power & FC?

How to do that? Can you help to explain in a bit more detail please? You're talking to a lady owning her first set of wheels here .
By the way is it advisable to do such things on our own? I mean, if something goes wrong, will affect any warranty?

hahaha dun worry about warranty, u just remove the battery "negative" terminal for 1 to 2 mins. Wat onli cause u is to reset ur clock and radio setting after installed the negative lug....

dun cause u any harm lah, u dun believe when u go back next servicing , the technician oso did tat without ur knowledge tat why alot of ppl thought dat after service by CNC alot of diff in odo meter reading....

For ur info, I had oridi forgo the 10oookm servicing,doing outside. I dun care the warranty, the most i dun claim my engine if really got problem, the rest still under warranty..

Hello treysha, so did you managed to rectify the engine oil problemo ?

Not yet. Dont dare to unplug the negative pole on the battery like advised by Feileong above... hehehh.
Feileong, are you talking about the main car battery under the bonnet? The positive seems easier to unplug, but the negative needs to use some tools to unplug it. Am I talking about the right part here? Still not sure if I should do it myself or wait till hubby comes back from overseas in a few days

About the engine oil, since I am due for 1st k servicing very very soon, I will get CnC to drain some it off during servicing.

But I will sure update the outcome here! Would love to be of some help to the other forum users, just like how some have helped me

Hello treysha, since your 1k servicing is due soon, might as well get them to reset the ecu at the same time mah ?

Anyways, have a great day !

Since ur babe's due for 1K servicing let CNC technician do for u lor, save the trouble..

If u wan abit perfomance of ur car, u can change spark plug(denso IXUH22 Iridium) and air filter to Hurricane or kNN.

Guess there are more enough for the lady driver..ehehehee

Hi IpohForte,

I just travelled from Sin-Ipoh and from Ipoh-Sin, clocked a total of 1200km. I noticed a full tank can last me 600km from Singapore to Ipoh and I still have 100km (dist to empty). Like yours, my meter constantly showed 6.5L/100km throughout the journey. I rev about 2500 - 3000 Is that good FC?
I am pleased as I can never achieve this kind of FC on Singapore road.

just want to share that this "Distance to Empty" meter scare the **** out of me the other day. early morning after low fuel warning come out still got 60+km to empty so i dun care, tot end of day pump one time full full. mid day 50k, then evening start the journey home still got low 50km. then stuck in heavy traffic the km to empty decrease damn fast... think jump to 40 then no more number... just show "Distance to empty -----" and keep blinking. and i was many kms far from the PIE exut(i pump only caltex). but still manage to reach my preferred caltex near my house. thou i know most prob got enuf petrol, but dun understand why 40km suddenly become ----. quite scary. told myself dun believe the meter anymore. muz pump b4 warning comes.

Mmmm....i think it is like this. My EX(A) will show '----' too after it falls below 50km (distance to empty).

simonsoh wrote:just show "Distance to empty -----" and keep blinking.

Our manual mentioned that when the low fuel warning indicated or below 50KM, it will reflect "Distance to empty -----".

Well mine is a 1.6 SX(A) with new rims, which was changed at Autobac and average FC on SGP road, is between 11 - 13. There's a difference also with the Power steering. It used to be Motor driven power steering(MDPS) but they changed to Hydraulic, which also have some effect on the FC, although not much. The Hydraulic Power Steering are better than the MDPS which they got a feedback that its too light. Thats the reason why they change to Hydraulic from MDPS.
Now my mileage is 1669 km. Will head to KL in mar. Hopefully can get better FC. Full tank can go up to 550 km, but that depends on the driver again.
I track the number of litres I pump and the distance I covered as I doubt with the mileage display.

Can I get some feedback on the accuracy of the FC meter in SX pls? do you guys rely on FC meter to check the FC on the car, or calculate manually (i.e. Monitor amount of fuel pumped and distance travelled separately)?

do both for a couple of months...now rely on FC meter
