Improving Fuel Mileage

[my3m]

Petrol prices are decreasing, but there are many ways in which you save fuel efficiency. Some tips i am sharing that can increase your mileage by 2-5km/l.

1. The first thing is driving style. Ideally, you want to drive by maintaining the momentum of your car. Try to drive in a way that minimizes your chances of braking, because that just kills fuel efficiency. When you see a red light coming, put the gear into neutral and slow down, and try to anticipate when the light will go green. Your car should be moving when the light goes green, and then switch to 3rd or 2nd gear depending on your speed.

2. Don't accelerate fast, gradually accelerate to an acceptable speed like 60 km/h or 80 km/h depending on the smoothness of the road and maintain constant speed. Again the 1st rule applies, try to drive constant speed and at the same time maintaining momentum of your car.

I have have seen countless times, when idiots accelerate, when they know they have to stop at the red light. Waste of fuel + you are wearing out your brakes.

2. Tuning your car, make sure your oil is changed, air filters, tire pressure can have an impact as much as 15%...... Make sure your tire pressure is set according to what is designed for ur car. It is written on the door jamb on the driver side.

3. Please for the sake of god, do not go for bigger tires than what your car was designed for. There are two reasons, one is a decrease in fuel efficiency, because bigger tyres have more rolling resistance. You have to apply more power to maintain speed. And secondly, Bigger tyres are not preferred because you speedometer will be showing you are traveling at 75 Km/h whn infact you are really travelling at 70.... Your meters will be messed up....

4. fill up your tank to 1/4 so that it lasts a week...... because if you fill it to the top, thats an extra ~30kg of fuel => more weight => lesser fuel efficiency

5. Alloy rims might improve your cars looks, but they are heavy and hurt your fuel economy....

6. Remove useless stuff from the trunk, extra weight means less fuel efficiency....

I have saved approximately 12,000rs in a by following above steps.... if 12,000rs is nothing for you, then you dont have to follow these steps.

I hate it when some driver accelerates the car when just a few meters away from a red signal :s Waste of petrol.

Nice tips man. I will try to apply them since I am learning driving now

 

[Waris Arsh]

that is a nice guide

 

[umair23]

Good guide. Appreciate it

 

[my3m]

Turns out it is more of headache to adopt this style in karachi, if u r driving like this
people horn behind u and u end up blockin all traffic....

still my car does 500km on full tank in city, which is pretty good imo

Best advice, CNG na lagwao gari mien.. Petrol k liye designed hai, petrol pe chalao.
Follow these tips, they will help ;D

nice driving tips... one more to turn off your car on red light and start when u know the signal is about to go green because now most of the signals have timers
[MENTION=25072]my3m[/MENTION]: i wonder you keep strict records so that you end up resulting in Rs.12000

My vitz has a system which automattically turns off the engine if you press the brake at a signal

na..there are traffic wardens..... the traffic light stops r not a problem....

Everything was superb, but messed up meter. Dont understand that point man

nyc, but breaking in the first place is bad....

hypermiler put gear into neutral 500m before traffic light.....

The feature is called eco-drive.. research it

bro we are not talking about features of car that save fuel,
i am talking about driving habits which can account for more fuel saving then feature of car....

as per my knowledge, my car is doing better mileage then new cars... because of my driving habit...

hmm it doesnt apply on Bikes as they are constantly moving even the traffic is jam nonetheless nice guide

 

[K3yser]

@OP: Nice tips man.

Theres something I used to do when I used to go to college in Korangi Industrial Area:

On long routes, some people tailgate large vehicles like buses, trucks and trawlers and since they're moving at decent speeds you ride comfortably behind them. The plus point is you are riding their wake thats got very little air resistance thus you dont require that much power from engine (hence low fuel consumption). I used to get behind those large 'Black Queen' buses going 50-70 kmph. Those who've played nfs etc will recognize this as 'Drafting'

The downside is that its extremely risky, I cant stress this enough. And its completely useless once you enter city traffic.

I think you mixed it up. Shouldn't it be the other way round in theory?

[MENTION=31217]BaqarNaqvi[/MENTION]: With a bigger tyre, your rim size is still the same, so the rounds the speedometer cable will be moving per unit time will be the same. However the end circumference of the tyre will be more than that designed. So, with a bigger tyre, (lets say tyre A, stock, has a circumference of 80cms while you put in tyre B, a bigger tyre, with circumference 90cms, so you're travelling 10 cm extra every unit time registered. Obviously, it will register the distance not by the distance actually moved, but by the calibrated distance the cable moves in relation to your stock size). Get it?

which car r u driving? any idea how much mehran/alto will do with a full tank? Thanks.

bro i am driving nissan sunny 2000c diesel engine, which is capable of 18km/l
but due to worst traffic condition in karachi road, it is doing 12km/l

i mean wtf, driving in first gear on bridge climb, its worst for economy...

bro mehran is lighter car with lighter engine, it should be doing goood on fuel economy...i cannot say value because you have to calculate urself....

 

[my3m]

another thing i might add is that mostly people fill their tire with 28psi... for comfortable ride...
the tire pressure for ur car is written on the door jamb, it is the cold inflation pressure....

they do not know, that when you drive car for 20 minutes, the tire pressure increases by 4psi.. because temperature increases in your tire while driving, causing air to expand (air expand wen hot and contracts when cold)....

so when you go to fill to 28 psi, you do not take into account that tire pressure has increased by 4psi ... u r actually filling it to 24psi cold inflation temperature which is hazardous, as low pressure can damage outer wall of your tire....
always fill 4psi above 28psi, which is 32psi....
