What is the technique to maximize mileage without slowing?
-
Hi,
I know that so long as you doon press the pedal too hard all the way when driving, should be able to increase mileage per tank.
But exactly what do you need to take note to maximize the mileage without having to drive like an old lady or retiree?
Does maximizing mileage mean driving slow?
interesting question? no? -
I doubt that you can contravene the laws of physics.

Stop and dun move. But seriously, I always advise this to my friends unless for those with lots of spare cash to throw on a car. If it is for family purpose, because of convenience sake, I suggest move house with better location better. If it is for work, make sure your work compensate you for the car use, e.g. maintenance, fuel, parking, etc, if not, change to a job that does. Always remember, your house is an asset, a car is a sunken cost.

Remove unnecessary weights from the car e.g spare tire,don't turn the aircon on,all windows up to decrease drag,turn off engine at the traffic lights(idling wastes petrol),decrease rolling resistance of tires

myth:travelling slower and at lower RPMS save fuel
truth:travelling within your vehs powerband(close to max torque) and shifting @ max torque saves fuel as your engine does not need to ovecome much inertia -
Breaking unneccessarily can also increase FC. Drive at a safe distance from car in front of u. It u see the brake lights lit, let go accelerator. I`m doing that right now and it does help. On expressway, don`t travel over taking lane at 70 or 90 km/hr like some idiots do.
If not in hurry, just let other heroes over take u, they are the ones who got extra money to burn one.

Using my bro's acc..(cos lazy to change)
Remove unnessary weight.
pump more air into tire.
servicing
or do lik wat i do i move to certain speed, i either step clutch or let it "kosong" gear let it roll till slower then put in gear step gas again. -
all these come down to having good judgement. How far you think you can coast to the traffic light w/o applying much brakes or gas, anticipate what the car in front of you is gonna do, how much gas to apply just to get the car moving, dadada... if you have driven your car long enuff, you should be able to discover what's the best efficiency you can achieve.
-
release the accelerator and let the car criuse. this can save a considerable amount of petrol thus goes further
-
don't forget good servicing as well ...
-
does using less viscous oil help?
like SAE 10 or 15 or if you are extreme (and if it exist, SAE 5)
(i ignored the "w" number since its irrelevant in Singapore. -
drive at a constant speed eg: 80km just remain 80.

Sometime back there was the fuel saving expert which showed he could go to Genting and back on a Mitsubishi Lancer with one full tank of Shell. Something like that lah (I may have gotten some facts wrong).
Anyway he had lots of tips of how to save fuel. The main one I remember is to drive gradually i.e. slowly speed up and slow down, and optimum speed for most cars is 80km/h. At this speed, the engine is most efficient and uses least petrol for each km.
-
depends on CC leh....my car's optimum speed is and i'm not joking....100Km/h...like i said before its gotta do with the enigne's powerband...bigger CC cars tend to be able to cruise at lower RPMs cos of the torque wheras Smaller CC cars tend to be more efficient at slightly Higher Rpms as they do not have torque low down...Originally posted by Shooting_Cloud:Sometime back there was the fuel saving expert which showed he could go to Genting and back on a Mitsubishi Lancer with one full tank of Shell.

I think what you said makes sense. However,Originally posted by Variodical:Remove unnecessary weights from the car e.g spare tire,don't turn the aircon on,all windows up to decrease drag,turn off engine at the traffic lights(idling wastes petrol),decrease rolling resistance of tires
1. will removing spare tire cause the car to loose grip on the road (less weight or downward force)?
2. turning off engine at traffic lights. this means many restarts of engine. Will many restarts of engine give any problem?
I am shall practise your 2 other recommendations :
1. turn off the A/C. I have enough of A/C from office which really is not fresh air. Thus, I am all for fresh air from the fan and will try to close the window unless really too hot may open a little.
2. keep tires pumped.
Others have suggested :
1. put to neutral when see traffic light going or is red and step off the accel.
I heard a rumor that auto cars cannot tahan neutral while it is moving. any remarks on this?
2. servicing : what is done actually that helps fuel efficiency when doing this? as you can see, I agree but dont really know how that helps in a technical way.
thanks to you and the rest of the folks! cheers! -
i watched a metacafe video and it says putting pure aspartane into the fuel tank can increse the MPG by 10 or smth
also have the correct tire pressure -
Actually Citroen has invented a stop and start system where when the car stops the engine automatically turns off.I don't there is a prob restarting the engine many times as I'm sure Citroen have carried out their research and tests.Originally posted by reddressman:I think what you said makes sense.

With regards to putting the car in neutral,
If there is a rear collision,the car may move forward more.
Without servicing,the engine will become dirtier.a dirty air filter limits the engine's air intake causing it to burn more fuel.
Another way to decrease fuel consumption is to use cruise control. -
Please.... how heavy is the spare tyre compared to the car?Originally posted by reddressman:1. will removing spare tire cause the car to loose grip on the road (less weight or downward force)?
Starter motor konk earlier? How many times are you going to do that in the course of a journey?Originally posted by reddressman:2. turning off engine at traffic lights. this means many restarts of engine. Will many restarts of engine give any problem?
Fresh air from fan = recirculation mode off? Not stuffy meh? Besides, how fresh can the air get? By doing so, get prepared to change your aircon filter more often (if so equipped).Originally posted by reddressman:1. turn off the A/C.

Doing so in rainy days can fog up your glass.

did u know that restarting of the engine wastes even more petrol than letting it idle?Originally posted by Variodical:Remove unnecessary weights from the car e.g spare tire,don't turn the aircon on,all windows up to decrease drag,turn off engine at the traffic lights(idling wastes petrol),decrease rolling resistance of tires

use semi-slicks or slicks!

Think of the various factors that affect FC.
Driving techniques: Heavy or light accelaration, warm up engine, braking
Road condition: Traffic lights, jams, slope, highway
Engine Condition: Regular maintenance, proper tuning, tyre pressure
Load: Weight the vehicle carry around
Usage: looking for parking space, waiting '5 minutes', poor route knowledge.
No point having a great milage when most of the milage is not productive. Like getting lost and circling the destination. Looking/waiting for parking space is also not productive. Parking in the upper decks of MSCP daily adds to the milage and FC, and you're going nowhere.
A 10Km congestion-free route that takes 15 minutes, consumes less fuel than a 7Km congested route, that takes 25-30 minutes. -
walk.
i once complete the half marathon.
mileage is 21km/ 0 litre petrol = infinity mileage...
solved your problem! -
not true.Originally posted by reddressman:1. put to neutral when see traffic light going or is red and step off the accel.

u can even always put to neutral even if it is moving... -
if i remember correctly, drivers in UK are required by traffic law to turn off their engines at traffic lights.Originally posted by reddressman:2. turning off engine at traffic lights. this means many restarts of engine. Will many restarts of engine give any problem?
it is to save the environment.
i guess since they implement it, should not have problem la -
The petrol used in every crank up of your car is equivalent to 30 to 60s of engine idling.Originally posted by uncle_abc:if i remember correctly, drivers in UK are required by traffic law to turn off their engines at traffic lights.
