[Discussion] Technical - Fuel Consumption

[jayz]

Hi all s4 bro, may I know for s4 spec 2 when does vtec kicks in? 5000rpm? Just want to know so I wont open vtec unnecessary and I can have better fc. Pls advise.

 

you can feel it when your vtec opens ma. the sudden burst of acceleration.

When Vtec is on, the sound from your engine and exhast will be quite loud for you to notice..

Hi bros, have you guys ever encounter the fuel meter running from center to both sides? i know if it hits reserve the meter will go from right to left. but mine is from center. like this >>>

my Spec3 with reserve till the last few drop, I managed to get 410km

 

using Shell V-Power

 

my full tank was 18.1Litre

 

320km with 11 litres of petrol, still have some more left before reserve.

RON 92 SPC.

 

i used this to gauge since my tachometer is faulty.

Does different EO affect fuel consumption? I was able to last more than a week with a full tank to and from work at Tuas, until I did my servicing n changed to AMSOIL 10w-40... Now I can barely last 3 days! Arnd 150km/full tank. Can't really see me odometer cause there's like fogging on the lcd...

I use Amsoil 10W40 on a 12 year spec I and can get 25-26km/l or 360-370 before i hit the reserve meter. Pump only 14L of fuel max.

 

I dun think is EO problem bah o.O

 

New bike?

[SgtClaymore]

This is not very true. With V-power, I hit reserve at 340km. But with mobil or Petronas, I hit reserve at 400km, which is 60km difference.

 

I gotta agree with this one!

[ah_dun]

My SpecII can only go 18+km/l. Petrol bar start running at 260+/-km. Most of the time with pillion. Total weight around 140KG.

[loo90]

any advice to improve fuel comp for stock spec 2? getting about 19.3km/L.

[tiku]

my stock spec 2 max 19km/l , 90percent on expressway, no vtec, slow acceleration...worse i gt is 17plus km/l .. only can live wif it

MIne spec 2 oso 18 to 19km/L,full time pillion about 130kg..full system blueflame and 40% vtec kick in...i think tats normal for spec 2 la...

[thrasher]

Spec 2 is a drinker. I get 22/23km per liter with a pillion combined weight 160 with a total mileAge of 380km till dry on a spec3, travel rpm 5 to 5.5k. If i always tarik then suck more lah.. Thinking of changing to blueflame fullsys in the future.. But i think after dynojet it should be okay lah.

[sihan0110]

My spec II I get between 22 - 24 km/L. Stock

[thrasher]

Wah how fast you ride

[sihan0110]

Most of the time express way will be 90 - 120

 

Normal road will be 70 - 90

like that your fuel comp good sia as most spec 2 posted to have 18-19km/L.

i guess is depend how you accelerate. my accelerate quite relax one roughly 3 - 4 k rpm change gear for the first 4 gear.

[Andy Teo]

I am riding a spec 1, and my bike fuel gauge starts to dance around 230 km mileage...and I normally topped up at $20 at $2.20 (95) per litre which means about 9 litres of petrol - is this normal? Shouldn't the fuel gauge be dancing only when I hit almost like 15 litres instead of 9 litres? Appreciate any comments from bros here.

[loo90]

dancing when ur bike on side stand or upright?
