nowonder u pple can get fc like 14-16...KNS fill petrol until like that of coz sure good fc la...

I normally fill till the pump auto stop then round the liters to the nearest full digit liters.

Got one time a PRC attendant filling my car, which I expect abt 34L then end up with 38L, that tank gave me FC of 14, (somemore that tank i stuck in jam at AYE for almost an hr) so bey chun wan some pple here top up petrol

Our car ave 12.5 - 13.5 si beh ho already, considering 50% city drive 50% HW

im gona go try out tis product from usa.....add into engine oil 1......plus valve cleaners n green oil for the petrol tank , if after 3 tanks of petrol got increase in mileage i will say my project is a sucess, will post again after i add those in the 1st tank .project will commence in a weeks time....normally my half tank is 230.....i will update here after 1st tank ok...peace

true to some extend, the thing that stops the valve is call pre-check valve ( i think) it works by having opposing gas pressure preset on the device, so as the volume builds up, the opposing pressure increases until such that it will release the catch on the lever.

after some wear and tear some valve release are less sensitive than others. then again my opinion is the difference is negligible, but the pressure at which the pump is pumping petrol would play apart, however as a petroleum company cash critical equipment, I would presume such pressure should be industrial calibrated standard.

hmm... too technical... not understand as I am not from engineering one :D...

but, FC is measure based on how many KM your ride have been run then divides it with how many liter of petrol you re-fill it back to your car fuel tank, right? :confused1:
So, it is not possible that your ride's FC will be good if your pump it till for extra 2 Liters...correct me if i am wrong. :D

so, even you calculate your FC based on fuel indicator's light up then pump 20 liter of petrol...also got chance your fuel indicator's light sensor spoiled, right? i don't believe those sensor got not fault tolerance :bleh:..

Nah the way pple are filling their tanks sure get good FC. :bleh: ;D

but hor , reali is the way ppl fill up tank meh??u should calculate wats reflected on the pump screen....like erm.....example its shown u top up 30 litres then u check back ur car how far has it travelled......subsequently 4 the nex tank .then u agar agar u should noe ur average consumption.use the amount pump and the mileage in ur car divide it.get the figures then keep it 4 reference 4 the nx few tanks.....should be average out liao lor.....n rememver driving patterns like heavy or light footed drivers.....kinda traffics??light heavy , highway smetink like tat....also mus come into consideration....a few tanks of the same envioroment u should be able 2 averageout....:) not the way u pump lah ...

Agree.. that's exactly what i meant...haha :D... no matter how the way you pump your car, just make sure that the tank is refilled at the same level that you re-filled previously. I don't understand why jliow thinks pump extra few liter will bring UP the FC.. if your car run 300km now and your FC will be nice is you re-filled with 20liter of petrol (around 15km/l) rather than 21liter of petrol(14.29km/l)...not math expert...but don't hesitate to correct me if my logic is wrong. ;)

but how to calculate the traffic style? mostly the time i spent 60 minutes on highway ..but stucked in the causeway is about 30-45 minutes... the about 30-45mins on city drive (where can only drive between 40-70km/h)... nakshire, time to show your math on this... :devil2:

yeah trying to break down everytink into easier calculation 4 the rest......if wana make it more simpler......average out by 3 to 4 full tanks.......drive ur own style heavy or light.....note it down, heavy or light traffices note it down on individual tanks...remember all tanks of fuel drive till red light comes on 4 the reserve....REMEMBER IF U REACH E, DUN STRAY AWAY FROM PETROL KIOSK.i agar red light on u still got 20km or more, dun push ur luck ok.red light on go petrol kiosk straight.pump it up check ur mileage n n how much petrol pumped in....take note.nx tank do the same red light pump , tis time pump same amount of fuel. then i guess easily work out the maths liao....my maths also no good lol paiseh.of course light traffic n a lighter right foot gives u more mielage ahahaha.oh yah , AMOUNT OF PASSENGERS ALSO LAH, miss tis 1 out.the amount of passengers u carry everytime take note of tat 2...i will be easier if mostly car wif u onli.easy 2 monitor, more weight more fuel 2 move.....especialy in heavy traffics

hmm.. sound so troublesome... aiya, just enjoy to drive, don't be so calculative lah...
even your FC is 11km/l..or 16km/l...our latio full tank only 50L... so, full tank only differential by 250km (your ride can run 800km if FC is 16km/l; 550km/l if FC is 11km/l) only mah... if measure by distance run... just one trip from JB to Melaka mah... not much save leh..

This methods, actually can have good FC as according to some fuel saving tips. put your tank always half-tank full instead of full tank. but i can not do that way...due to driving out from Singapore must contains 3/4 of fuel :crycry:

My Latio low fuel indicator comes up at 35Ltr at normally 360 to 380 km, that means reserve still got another 10 Ltr. My calculation of FC is based on mileage traveled against the last top up..so on an average most of the times I get about 11.5km/ltr. And i have also downgraded from Mobil/Esso 95 to 92 with no significant increase in fuel consumption or loss of power.

my full tank only 380km. But can only pump 36l , why is it so when our tank is 50l ?

I think you always pump the minute the low fuel indicator lights up...normally it will light up at about 35ltr so that probably explains why you normally pump 36L and then your tank is full...

i realized...

the FC numbers i get fluctuates alot...

hmm.. guess i can chip in some few cent advise too.. hehe... :bleh:

its hard to constantly monitor ur FC weekly or every pump. no matter pumping of petrol till the tip or till the refilling guage stop. juz use the distance clocked and the amount petrol pump. should have an average of ur car FC.

But once again, even doing so, ur car FC still depend for that week (if monitoring weekly basis) hows ur mood affect ur foot. and dun forgot the numbers of passager u are taking for that week? and road condition?

but bottom line juz enjoy ur road.. dun let FC take over u.. if not juz spend MORE $$ to improve FC lor.. haha..  :devil2:

my 1  cent of advise.. no hard feeling..  :bleh: :bleh:

cheers..  :yehyeh:
