Juz for sharing purpose so that newbie can read this thread n save the hassle to do a search.

not to worry dude.. im reading it.

[eddie23]

sorry to touble u guys again .today i just pump my fuel tank to full ,after some calculation my bike 1 litre petrol can only go abt 18 km.is it high consumption ? or normal.i riding a spec II.

[IceZ]

its consider normal IF u open ur vtec offend...lolx...

mine till 300-320 b4 hitting reserve.

[bt]

wa.... that's quite scary leh..

 

how's ur ridin style like? a lot of first/second gear dragging? vtec usually on?

[eddie23]

i on my vtec sometimes only.cos i travel quite a lot on expressway.i normally travel at 100km/h but rpm usually around 6 - 6.5

[Manzz]

A lot of factors affecting.. Tyre pressure --> Insufficient will lead to lotsa drag and thus consume more petrol..

 

Wind Resistance --> After I put my sai tao then i notice my petrol consumption oso went lower.. but only a bit like 0.75km per litre more..

 

Rider's weight --> the more heavy the more power needed thus need more petrol..

 

Got some more lah.. but forgot some liao..

[spec3]

Look like all s4 can easily hit over 300km per tank....den my bike might send to c doctor liao...

maybe just minor tuning on your carb will do....most impt to see what size of the pin jet....so far, my PB1 has been using factory setting and mileage covered for full tank is ard 380km

[pigsmu]

Do u normally pillion ppl?

 

Without pillion prolly ard 21km/l (calculation b4 I got attached). But when I pillion gf ard 18km/l (strict calculation is like 19km/l lah... But at times i ride alone mah).

I've got some comments for grounding.

it's true that after grounding, you feel the difference when u ride.

The response is nice to hear, should i say more garing (in malay).

after some time, i noticed that the 'garing' feeling no longer there.

It could be that I'm used to the feeling such that you can no longer feel the difference.

But what I'm quite sad now is, I found out that my fuel consumption has gone up.

Which means before grounding, i could go 350km with Mobil F1 before hitting reserve.

Now with also Mobil F1, I could hardly reach 330km before reserve. 310km will start blinking. My next servicing, what I wanted to do is to take off the grounding wires and I want to see if I can clock 350km again. Just sharing my findings to you all. Decide wisely.

mine is vtec 1 left 2 bars at 210 ..izzit normal ??

yeah, maybe due to other reasons then grounding... maybe you take out the ground and see the effect first.. then share with us again...

 

i also did my grounding recently... FC slight increase a bit... from 310 to about 320km... not conclusive cos i also changed to K&N air filter.. so more than one factor...

[bt]

hmm... perhaps its good to let all know. the plus and minus of grounding.

 

anyway somehow i noticed that using jb v-power mileage like significantly reduced leh..

 

sg power95 - 370km hit reserve

jb vpower - 330km hit reserve

 

:giddy:

 

anyone shares the same problem? or perhaps i should try jb's caltex next time.
