HELP FC bad

[DarkLord]

Here's my contribution to VOGS regarding FC.

 

Fuel Consumption

 

By DarkLord

 

VOGS 8th MM

 

 

1. What is fuel consumption or FC?

 

Amount of fuel consumed vs mileage of car travelled. Unit of measurement - Km/L.

 

 

2. How to calculate FC?

 

Distance travelled divided by amount of fuel used. So in order to have a more accurate calculation, top up to full tank and run the car till the next top up. Divide the mileage traveled by the amount you just pumped. Repeat this for a few tanks till you have an average FC figure.

 

 

3. The average FC of Vios?

bro, you think he print $$$ izit

[Vtim]

wait for you engine to run in, FC should improved.

 

BTW wat's these 2 mod ???

 

- 2x RMk 202

- VS

opsss.... bro dun u hav engf mods olreadi....! interested in another mod?? Zex Nos system...... (im selling mine)?

Bro, it could a simple case of travel pattern, my usual FC is about 10km/l for 60% HW 40% City (Jam most of the time, more like 80% city driving)

 

Whole of last week, I travelled to a different location for work. 80% HW 20% City (smooth traffic).

 

FC was 14.1km/L for my Auto Sunny!! Unbelieveable!!

 

A 41% improvement for FC. No new parts added, same right foot (rpm <3k).

 

Oops, wrong explanation. running in have some weird fluctuation if everything else is ok.

once I hit 8km/l nothing change. check everything, nothing wrong, next pump back to normal FC

My car is only 2-3 months old. so far only 5000km

[Danieltan07]

city has good FC

[Danieltan07]

how long is the run-in period?

 

my car is about 3 months old and travel about 5000km liao.

 

RMK 202- http://rmkps.com/product.htmimproves air intake (thus improve ....) while heards it only works for auto car. and usually need 2.

 

VS- voltage stabilizer. battery current tend to Fluctuate. VS - suppose to enable to stabilitier the voltage - prolong battery life, improve...

Good luck then. Continue to monitor your FC and see.

 

Try filling to full, then wait until the warning light turns on.

 

Actually, a better way is to count from 3/4 full to warning light.. It is because different pump clicks at different time when you top up. So, start counting when it hits 3/4 full, and average the KM over a few tanks.

FC was 14.1km/L for my Auto Sunny!! Unbelieveable!!

 

 

Wow... that's a lot for sunny auto... how long have u been driving urs? i just got mine 2 months back and the FC is like 8-7km/l. is this normal before run in?

[Osiris]

I guess what I am trying to say those cities same pattern as you? You have to compare apple to apple.

Even same route, smooth traffic and heavy traffic have effects on FC...

[Osiris]

9 months. FC went up abt 5% after 10k servicing with syn oil 5w40. Run in FC varies from 8-10.5km/l now constantly about 10.5km/l

 

What's your driving pattern? A lot of city driving?

[Serene]

50%HW 50%city ba.. my dad driving most of the time. and he will rev to 3k when moving off.

[Osiris]

me 1 to 2 gear <3k. But I don't do it if there's a jam. Does he rev till 3k everytime just to move off regardless of traffic condition?

Also tyres pressure, did you check?

[Serene]

ya.. i found out something abt the tyres pressure. haha cos we din pump air for 2 months after we got the car and half tank i can only travel like 120km den i just pump air last weekend and now between 3/4 and 1/2 tank 120km liao..

 

this is our first family car so dun noe a lot of things.. can only see the fuel dropping and dropping...

[Serene]

if traffic jam he dun rev.. only when traffic is clear in front then he rev.. but something i see him rev >3k... den i for him.. he is driving company lorry so i think that why he is heavy footed...
