ways of saving petrol

[zart]

sianz everytime go jb get cheap petrol..

im thinking ways of saving.. small effort oso count..

trying to change my riding style..

 

 

1. ride at 80km/h gear 4 or gear 5? i think gear 5 cos lower rpm right?

2. 92/95/98 and so on.. which one worth money?

3. ride fast or slow.. i feel no difference .. so i always ride close to speed limit or faster.

4. expways or major rds? i think major rds..if less traffic lights.

5. engine brake got use more petrol than clutching in/idle?

6. any difference riding on uphills? i always ride from bt pjg to bt timah.. alot of hills.. if not i go by bt batok rd..

 

give your comments guys..

ride @ 20km/h.. ok joking hehe.i always try to maintain speed when riding @ exp.and most of my riding is done on expway so its 90km/h most of the time for me.

Gentle acceleration with constant speed should affect FC the most i think

[Speedpass]

Good maintenance like constant lubing of chains , change of oils , plugs n other worn out parts contributes partly to fuel consumptiom . A dry unlubricated chain is more likely to burn more petrol .

 

Riding styles like smooth n steady acceleration , progressive braking is oso recommended . Using of engine braking instead of the brakes helps too .

 

Keep tyres at an optimum level as stipulated by the manufacturers . Under inflated tyres consumes more fuel .

 

Last but not least , ride less n take the BMW route .

[deckard]

I agree!!! BMW is the best !

[apitBIOL]

means fat people = more fuel consume?

[zart]

if chain not properly lube can cause fc... meaning bike need greater fuel to burn.. same like heavy riders..pillion.. no offence to em!..

Just wanna comment on the part on engine braking. Though it is a so-called safer way of braking (reduces chance of rear wheel locking), it actually consumes more fuel as it 'forces' the engine to rev up again after dropping gear. Everything else held constant, which do you think consume more fuel - an engine spinning at 5,000 rpm or 1,500 rpm?

 

No offence intended, just sharing.

The conventional wisdom is that everything else being equal, fuel consumption relates mostly to throttle position and engine RPM, with RPM being the greater factor.

 

For example, if you were lugging the engine along at very low RPM in top gear, but you had the throttle wide open, it wouldn't use as much fuel as if you were running at high RPM with a very small throttle opening. In the high RPM example, the engine MUST have a certain minimum of fuel to stay running and maintain power and/or speed. In the low RPM example, the throttle may be wide open, but the engine will only use so much fuel because that is all it can burn.

 

This means that if you riding and off the throttle completely, with the desired effect being engine braking to slow the bike, say dropping from 4000 RPM to 1000 RPM, fuel is cutoff and therefore that initial high RPM doesn't really hurt the fuel mileage at all. There is no fuel being injected in this scenario.

So... you are saying that there isn't really much of a difference in fuel consumption between using engine brake and using foot/hand brake?

[chanjcv]

haha.. well just that it wears of your piston faster? well, i think what he says makes sense (:

[danielsin2]

keep ur bike stock??

[Cool79]

don wack the bike lo

slowly ride

[DVD]

Acclerate gradually

Petrol is used the least when cruising

Comsuption is mainly on stop & go

[Demon]

don wack the bike lo

slowly ride

 

Don't wack the bike, yes. Slowly ride, No.

 

Fuel consumption (FC) is a function of speed, and speed is distance over time. When you ride slowly, the FC is higher than riding faster because you cover less distance over time . However the FC will increse with speed up to a point whereby the FC will begin to drop, that point is known as your economical speed, the speed where you can achieve the farthest distance using the same amount of fuel.

tell the government to let the petrol prices drop after erp rises

[Guest Twat]

Stop riding and walk.

take Bus lor ....

i think i roughly get wad demon is saying and i agree with him..

eg... at gear 6 is 5k rpm and u are at speed x..

then u wanna slowdown ..

drop to gear 5 ...

u are slightly lower than speed x(after closing throttle) and for gear 5 to be at slightly slower than speed x..

rpm muz go up mah rite ?

coz gear 5 is a slightly more acceleration ratio than gear 6?

and i dun think fuel consumption is a factor here ..

coz the fuel is already converted to 5k rpm of power..

when using engine brake is kinda cutting off the already used power ?

m i ok to say tat ?

 

but for me .. i feel use engine brake like.. will cause SLIGHTYLY more wear and tear ?

coz my mentality is clutch will wear .. chain will loose.. piston rings kinda under stressed also ?

depending on situations .. i rather juz clutch in and wear my brake pads..

heh ..

 

dun flame me if i offended anyone plz ..

juz my thoughts here ..

6. any difference riding on uphills? i always ride from bt pjg to bt timah.. alot of hills.. if not i go by bt batok rd..

 

give your comments guys..

 

1.) using the correct gear is very important. ( you can't ride at speed 30 using ur gear 6 right? u need to open more trottle to bring the speed up..)

2.) i usually pump jb petrol. however when there is a need to top up petrol in sg, i stick to Esso8000 cause i feel that as compare to car, bikes are of not much different. (maybe because i ridding small bike)

3.)hmm, i alway exceed the speed limit. it is ok to exceed by 10 like that la.

4.)personal preference. and also depend on situation.

5.)engine brake i feel that it require more petrol. (the petrol convert into a "pull" energy to slow down ur bike)

6.)ridding uphill sure need more power, resulting in more FC. (imagine u are on a bicycle)

 

afterall i wound advise everyone to apply all the brakes together .( rear front engine braking.) though all sum up to abit of wear and tear. -->no choice one mah.hmm.

take bus? walk? then dat defeats the purpose of dis thread on how to safe FC.

 

easy.....ride bike slowly to nearest MRT, bring bike inside MRT go to station nearest to destination den ride out to yr destination.....hahahaha....

 

jus joking

[Demon]

take bus? walk? then dat defeats the purpose of dis thread on how to safe FC.

 

No matter how conservatively you ride, it defeats the purpose of trying to save petrol if the bike is not maintained properly.

 

[Yatz86]

don always chiong ure throttle....must ease a bit...my 2 cents worth

[Guest stages]

lol... U like this say will offence alot of ppls de lei bro!!! hahas

[GTboy]

toking about sportsbike....comparing between the diff types the diff models. tell me...r there so much diff in FC in those diff models?? i guess not so rite??

so when u buy a sports bike....which concerns u more? performance? or FC?
