Driving Economically

[Ryan]

Hello. As fuel costs continue to rise, it’s getting more and more expensive to run about in our beloved motors. The following are some bits and bobs I’ve picked up, as well as some common sense, that can be applied to make that tank of fuel last that wee bit longer.

 

 

Don’t hammer the accelerator

See the old lady in the micra you just thrashed away from at the last traffic lights? There she is right behind you again at the next lights. There’s no need to accelerate hard away from junctions, roundabouts and lights – chances are you’re going to have to come to a halt again soon.

 

As a rule, the more you press the accelerator pedal, the more fuel you’re putting into the engine. You should never have to floor the pedal. This is opening up the throttle fully and putting as much fuel into the engine as possible. You’ll probably find that you can get similar performance by raising that heavy foot of yours slightly. Try it.

 

Accelerating more gently than usual will use even less fuel, and I doubt you’ll notice much difference in your journey times, especially in traffic.

 

 

Drive a little slower

Driving at 35 or 40? Or 80 or 90 on the motorway? Sticking closer to the speed limit will use up less fuel, as you’re not putting as much into the engine. There are other benefits – you can stop quicker in the event of an emergency, and you won’t get stopped by the coppers for speeding.

 

 

Avoid stop-start driving

Tying the previous two points together – a smooth journey is a more efficient journey. If you accelerate hard away from a junction, then slam the brakes on again at the next, you’re throwing away all that built up speed and energy (while using up more of your brakes). Smooth acceleration and gentler braking will cause less fuel to be used up, and cause less wear and tear on parts. Obviously don’t drive like a blind/scared 90 year old, but y’ know…

 

 

Close your windows on the motorway

Cars are pretty aerodynamic objects (compared to, say, a double decker bus or skip). If you have your window open, you’re turning the aerodynamic shell of your car into a parachute, creating drag. This obviously means the car has to work harder to keep at your desired speed, as it’s fighting against more wind resistance.

 

 

Use aircon as little as possible

Air conditioning systems use fuel to run, so having this hammering away for your entire journey will use up even more fuel. If you're warm, open the windows! (unless on a motorway )

 

Obviously summer is upon us, so common sense is required to keep things at a happy medium between 'efficiency' and 'having a small paddling pool under your crotch'.

 

We have a little battle here between aircon vs drag vs keeping yourself cool – apply common sense please. If you don’t have any, ask a friend.

 

 

That roof rack box

The one from your last trip? Is it filled with air? Objects like this affect your cars aerodynamics too, so take ‘em off if they’re not being used.

 

Even worse if it’s full of crap. This goes for any extra stuff that you ferry about in your back seat or boot all the time, as you’re paying to carry around the extra weight, making your accelerator and brakes work harder to speed up and slow the car.

 

 

Keep your car well maintained

Bit of an obvious one this. A well-maintained car will run more efficiently than one that hasn’t had a service in a few years. Keeping oil fresh, changing filters and running on decent tires will all help a car run more efficiently, not to mention safely! Clogged up filters result in wasted power. Keep your tires inflated too – squashy tires are dangerous and inefficient.

 

Avoid short journeys

If you can, avoid using the car for piddly little journeys of a few miles. Walk it or bike it if you can. A cold engine uses more fuel than a warm one. And you might actually give your legs and heart a little exercise.

 

 

 

Here endeth my blah-de-blah. Hopefully it'll be of use. Feel free to add your own tips and thoughts. Try and keep it constructive

 

Happy driving!

[Joanne]

get a new job closer to home.... like meeeee!

[K.C.Leblanc]

get a new job closer to home.... like meeeee!

 

Same here, now walking to work every day

[everton4europe]

Change to diesal. Filling up once a month now instead of 3 times a month!

[elsiegee40]

I would also add:

 

Lighten the Load Don't use your car as a cupboard... the less weight your car is carrying the less power needed to move it.

 

But like the above, I live near enough to school not to use my car It's a daily bike ride for me!

[tech_guy]

I'd love to be able to walk or cycle to work - I have a 20 mile journey each way and have been trying for ages to get a similar decent job in my home town.

Actually, new, like for like cars you have to do alot of miles for a diesel to work out cheaper once you take the extra cost of purchase and maintainance into account, and with diesel prices going up faster than petrol it will only get worse.

 

Ive got one;

 

5th gear is NOT the only gear your car has got

Driving in the incorrect gear is not only damaging to your engine, mounts, exhaust and other things, it is far less efficient on the juice. 30mph is not the speed at which you change into 5th, infact the only time you should be in 5th is on national speed limit and above roads. Depending on your car 30mph is normally around 3rd gear, possibly 4th in a smaller car or if like my car 2nd gear for any less than 30mph.

 

^ thats one thing which drives me mad. Ill be in a mates car and he will come to almost a complete stop yet insist in pulling away in 2nd or even 3rd. I dont get it, can people not hear the engine crying out for mercy, never mind the clang as bits of exhaust pipe fall off from all the rattling the engine makes at such low rpm!

why carry around enough fuel for 100miles if you only need to do 50

[ICT_GUY]

I would love to have a small diesel van, non turbo for pottering around with the dogs in. Unfortunately what it would save me is out weighed but the cost of purchase.

 

Also, with the constant tax increases, what car can a family of four (plus four dogs) buy that does not cost the earth in taxes yet is still big enough to get us all where we need to be?

[ICT_GUY]

The weight of fuel is marginal compared with hunting around for a petrol station every day.

I was always under the impression and have read on several sites that the higher the gear the better.

If I drove my car in 3rd at 30 it would sound awful and the revs would be in the red almost. I always drive it in 5th at that speed, occasionally 4th

[Elky]

Get a motorbike! I'm doing 70 miles a day to get to work and back and it costs £7.00 per day! Not bad for 70 miles

[Ryan]

Bloody hell, mental. What you driving? If i did 30mph in 5th, it'd be the transmission pushing me forward, not the engine - the revs would be far too low! (2 litre turbo diesel)

I ended up buying my citroen c3 hdi after going on the site.

Nearly 70 mpg and only £35 a year road tax. Nice

[dgsmith]

I think if 5th gear is needed for 30 suggests then that a problem, but at the same time whenever I am at 30, still yet to change to 4th, I can hear the revs starting to cry out for mercy! I only change to 5th when going at 40 for over half a mile or for any speed over 40 (Corsa C, 1.2, so not a vast amount of power).

[Sirbendy]

It always staggers me the people here that have Astras the same age or newer than mine (1997 P), with the same or smaller engines (1.6 8valve) and are astounded at the fact that I can drag in excess of 400 miles out of my tank when they struggle to get 250..

 

Bear in mind it's an automatic as well..I do follow most of those tips. Gentle acceleration up to 50, when lockup of the torque converter kicks in and it's at it's most economical. If I need to overtake, I keep the throttle light (as usual) and just tap the sports mode button to drop the gears, then turn it off when I'm done.

 

I try to judge for minimal braking and "rolling start" at traffic lights (saves the inertia). When I did my "usual week" trips, I could get a fortnight from the tank which was lovely...now I've cut back, I'm managing 3.5 weeks..hopefully a month.

 

Most of the car's trips are work trips...BUT..there appears that there may be a bus leaving a few minutes walk up from the house at 7.35am, dropping off right outside here for 8.02am...returning at 4.53pm..which is close enough to my hours to be useable.

 

It'll require me leaving early, but if I'll be here earlier, it's little or no odds I say.

 

If I used the bus to work...and I manage at least 3 weeks to a tank with work..it could be a 2 month tank or more..we use the local shops as a rule, we've signed upto a "weekly veg box delivery" scheme, there is even a local butcher etc 20 minutes walk away.

 

I need to look into getting a monthly ticket, which they apparently do. It also seems I could catch route 44 from the school and get to pretty much anywhere I need to go in Telford..which is nice.

 

My mother in law is carless for the next 6 months or so...and it's not affecting family life much, once the kids have adjusted to walking and public transport..

I thought generally the same...

[Ryan]

To a point yep. If you're over-revving in a certain gear at a certain speed, then shift up to lighten the load.

 

But you can, as far as i'm aware, start causing damage to your engine, gearbox etc by making it work too hard in too high a gear if the revs are too low. As for pulling away from stationary in 2nd or third, that's just lunacy.

[SYNACK]

I thought generally the same...

 

It is better so long as the car is not struggling, using my car as an example I can travel at 50kph (30mph) in fifth without the car struggling at all at low revs (practically idle) as the engine has the torque to keep pulling the car along (2.5L V6).

 

This efficiency problem only occurs when the engine starts to stutter meaning that it does not have enough torque to keep pulling at that speed in that gear. Top compensate for this and keep the car moving forward you have to add more gas into the mix and the car engine will kind of rattle and shudder because you are pumping in more gas to the cylinders than it can burn due to the load on the engine. This wastes large amounts of gas as it is pumped into the cylinders but not combusted. This effect is made worse by the fact that when in this state the load on the engine is very heavy and wears out parts quicker, also due to the lack of complete combustion it dirties up the spark plugs which makes your car less efficient.

 

So long as your car keeps pulling forward comfortably then your fine and using less gas by lowering the revs, it is only when it stutters or has real trouble pulling forward that you are wasting more gas.

 

The same kind of thing happens when you floor the gas pedal. The engine does not have enough air in this instance to fully combust the gas so the extra just gets fed out the exhaust system, most wasteful.

[ICT_GUY]

Ok a general rule, keep the revs above 2000 when the engine is under load.

 

The higher the load the higher the revs should be. Going up a steep hill you would want to be higher. Coasting on a low gradient hill you can be lower down the rev range. Mechanical sympathy I think is the general rule.

Ohh how are you finding it? I'm thinking of going along the same route. The bike is fab for just me but long journeys and passengers need something else. Haven't found any long term reviews and am abit worried about the stereotype about french car build quality.

 

the bike is a great comfort on fuel though. At the moment about £15-£18 fillup and getting anywhere between 144-175 miles Plus tons of spg's

I disagree. I'm getting over 150 miles extra to a 60 liter tank now I've got a diesel car. Yes, it's more expensive, but over the course of a month I'm getting an extra 500 miles I otherwise would not have.

thankyou gordon brown lol

[Quackers]

I did notice my fuel gauge moving fast cruising around 140mph on the M6 Toll last week My engine must be a prostitute, it sucks like one. 2.0i Turbo petrol guzzles round town, i get 250-300 miles off £80

[Ryan]

thankyou gordon brown lol

 

Yep - let's all bear in mind that at best he's not helping things, and at worst he's sending this island down the crapper.
