Factors Affecting Fuel Consumption

[hefraz]

Dear Forummers,

Dun know the reason why u choose Toyota. But for me, FC is the main reason. Below are some factors that are affecting the FC. Most imprtant, These factors are the one that we can control.

Hope the infor helps.

Please correct me if I'm wrong. Addition factor I missed out are welcome. Let's share.

1. Be gentle on the gas pedal -- Driving with heavy foot will increase FC more than we expect. keep ur rev below 2400 when moving off well be good.

2. Removed extra load -- Try to carry the min load . Keep ur trunk empty unless needed.(No, you dun have to drive on empty stomach just to reduce the 1kg)

3. No waiting -- Try not to wait for ppl leaving the engine on for more than ~3min. (better to off the engine).

4. Keep the pressure – Maintain you’re tire with the right pressure. Insufficient pressure will increase FC due to friction resistance. Too much pressure will decrease driving comfort & need more braking distance.

Pump ur tyre while it is not hot. More accurate reading of pressure when tyre is cool.

5. Keep moving -- Cruising will have better FC than city driving. Take the longer route if cruising is more possible. (In my own prediction, an extra 4km is still worth it rather then start & stop for more than 5 times.)

6. Anticipate -- Try to anticipate the traffic flow rate. dun brake too often.(Brake if you must ok) . I will look out not only for the car infront of me, but also the next car infront

7. Keep cool?? – Of course driving w/o the air-con can improve FC. (Too bad I cannot drive w/o it.) .

8. Modification -- Some mod will help, some won't. Choose wisely, do it the quality way not the quantity way.

9. Maintain well -- Keep ur ride well maintained. (Use better engine oil)

BTW I heard that if u pump petrol at night will be more worth for the buck,. Why, it’s the cold , petrol is more dense. Dun know how true.

Factors out of our control.

1. weather -- cold weather improve FC. Hot weather the opposite.

Hope this helps…

This one works really well for EFI engines it seems. Since the EFI unit cuts fuel to the engine the moment the vehicle starts coasting. Anticipating what the guy in front is going to do and coasting instead of breaking helps.

I have also heard the 'pump in the evening' tip a few times. But not sure of it's significance

Yes, It's true according to J Clarkson. Also I used to save some pennies by pumping petrol in the freezing mornings in the UK. It really works..

well u cant exactly compare uk machan cos their traffic system is coordinatd...their roads r gud n so r their drivers...

To add to that list;

Manual shift driven cars allow you to change to highest gear as soon as possible But you have to do it properly. Otherwise the engine will start knokcing resulting in more wear on parts.

Keep shutters up at high speeds to reduce air drag

all of these are kinda good..

but i dont think any of the activities consume that much fuel as flooring the gas, and driving on high revs.

cos think of it, you try to keep out excess weight out, but how much of this CAN you do. normally the only heavy movable items in a car are the passengers and the spare wheel. Keeping a bunch of books at home or the little little things in your glove compartment hardly matters, right think of it... physics wise the energy required to accelarate a vehicle to a speed is (mass)*(velocity)*(velocity)/2.. obviously the velocity doesnt change... so its the mass that matters, and how heavy is the car compared to ALL the removable items in the car...

1. Be gentle on the gas pedal -- Driving with heavy foot will increase FC more than we expect. keep ur rev below 2400 when moving off well be good.

Sometimes not giving enough revs can also be a problem, if you put too much load on the engine it can also increase your FC, try and keep the car in an appropriate gear for the speed that you are doing.

Also when coming to a stop, dont coast in neutral, always select an appropriate gear and use engine braking, this will also reduce wear on your brakes.

Keep to a constant speed, always changing your speed can also affect your fuel economy.

This will work better in the morning as the petrol has had a chance to cool down totally and is even more dense than at night or in the evening.

sweet cos i never see daylight wen i go to work n get back home

Important Thread after a long time i guess...

Yah all the factors are true...Neva heard of the pumping fuel in the mornings or when its colder situation before.

guys wut abou the heavy fiber body kits n useless heavy big spoilers ?

guess they wud be added weight too....
