Just found a website which calculates the miles per gallon on your car...

www.guycroft.clara.net/utils/mpg.html


its really good.

I get on average 32 mpg - mostly short journeys, I have a Corsa 1.2 - 9 years old. Anyone know if this is a good mpg? What's your mpg????

Thanks

They probably wouldn't were it not for the absurd system we have where distance is measured in miles, efficiency is measured in mpg but fuel is measured in litres.

It's alright for a petrol, but not great. My 54 plate Clio (1.5 diesel 100bhp version) claims on the specs it does a 66 average, which is just wrong. My average tank is between 40 and 45, but on those rare occasions I'm on country roads and doing an average of pretty much bang on 56mph in 5th then I can get it to average above 60, but it's rare. A 70-80mph motorway run will average around 45.

I drove into US from Canada and petrol there was in $/US gallon whereas in Canada it was $CAN/litre and I was paying in $CAN In order to try work out how much it cost to compare with here and in Canada I had to convert US dollars into Canadian dollars and pounds, US gallons into litres and imp gallons and kilometres into miles. By the time I'd reckoned it up and rounded figures up and down the numbers were completely inaccurate. No point anyway cos it didn't effect the price!

The claimed figures for petrol cars seem hopelessly optimistic - my car is supposed to be 37mpg but I rarely get above 30.

The diesel that preceded it was listed at 41mpg and did 41mpg.

I think your right.

My car (2002 Corsa 1.2 Easytronic Semi-Auto) has book figures of 42mpg, which I can match or surpass on long runs. However, seeing as most of my driving is town driving with lots of stop-start, short journeys, I'm lucky to get much above 32-34mpg.

The trouble is, there are so many factors that effect fuel usage that’s its practically impossible to come up with an exact figure of how many mpg’s you should get.

What is 'roughly', and why would you subtract it from the figure obtained by
miles/(litres/4.54609) ?

:)

Little Buzz
03-06-2008, 16:59
Roughly is inversely proportional to litres.

As litres tends from 0, roughly tends to 0, so if you've used any fuel at all, it's easiest to ignore it for calculations on a single car.

The fuel represented by Roughly is collected by the government at night, and over all the cars is adds up to about 47,000 litres a year. This is used for ministerial cars, and the excess is sold back to the public, thereby earning double duty.

Maybe!

How much would it have to cost to drive for you to give it up - even if you are a Rothschild and therefore don't care for such trifles as actual cost, there is always an opportunity cost - the 50p a mile you are spending on petrol can't be spent on something else, so I was just wondering at what level you'd decide to get something more efficient?

With fuel costs so high (and likely to stay that way) some quite interesting options become financially viable - for example I'm considering getting the 1.6 petrol taken out of the Ka and having it replaced with a diesel of some kind, which will not only half the fuel costs (and pay for itself in a couple of years) and reduce my VED, it will also make it way quicker.

When everything is reckoned up, particularly the higher initial cost and then depreciation you might find that there isn't all that much difference and it might not be worthwhile. I once worked out the overall cost of a brand new Renault Clio v a high mileage 4 year old Saab 9000 turbo and the Saab was cheaper overall, it was a far better car and it lasted longer. Big second hand saloons are a very good buy, have a look on eBay.

I know what you are saying, I was idly looking for an LPG Jaguar a few weeks back :-)

I do quite a lot of miles though - and this idea for the Ka is only an idea, but I do quite like the idea of having a car that is much quicker than it looks (the 1.8 tdci Ford engine can reliably give 150bhp/240lb/ft, and the Ka only weighs 1000kg) but is also efficient.

The Ka is our main car at the moment, but will become the second one and probably stay that way until it falls to pieces, so depreciation isn't an issue, and I think it would be tremendous fun!

No, I would never sell the Jeep purely on cost. Why would I want to spend it on anything else?? I'm a car enthusiast so why would I book a foreign holiday, or even one in a hotel, or the latest 42" flatscreen telly to overpower the living room, or smoke cigarettes, or drink beer....

Your ford ka. Your idea of removing the 1.6 petrol for a deisel and expecting to pay for itself in two years is not viable unless you travel a considerable mileage. The electronics would be a nightmare and driveshafts, exhausts, linkages would all have to be made to order. Finding a garage to take on such a project in priority over normal servicing and repairs would be very difficult. Then your insurance company would need to be informed and will no doubt stop your policy and refer you to a specialist company. Is it worth it for a ford KA. Personally I doubt it. Reducing the VED would be a minefield of its own to prove its new emissions. And it probably won't make it quicker!!

I thought I share that with you all.

I have a 12-year old Audi A4, 1.9 TDI. 90bhp. Typically in the past it did 45mpg, driving pretty much full bore.

Driving from Sheffield to Gatwick Airport, south of London (including a detour via Kettering on an A-road) I decided to try to minimise my expenditure.

I kept rpms below 2500rpm at all times.
Never exceeded the legal speed limit.
Always switched gears as early as possible.
Only accelerated gently.

Now keep in mind this is mostly motorway miles. I had filled up the tank before I set out and once arrived, I filled it back up again. I had used 16.4 litres and I had driven 237 miles. Unless I screwed up the math, that's 65.7 MPG.

So I plan to beat the rising fuel prices, by driving slower.

I'm currently applying above's technique to my daily commute from Gatwick to Carshalton, an equal mix between motorway and urban miles. If anyone's interested, then I'll share my mileage calculations with them once I have compiled more data.

On the motorway it's not an issue, plenty of slow-going trucks and slow lanes. And there were plenty of others going slow as well.

And yes, it was quite boring. I prefer the thrill of speed myself. But money's tight, so I was listening to audiobooks to cheer me up. And if it costs me £5 less to arrive half an hour later, that's becoming a worthwhile incentive.

I find that a good audiobook in the MP3 player helps with the boredom. Driving's just another chore nowadays. Gets you from A to B. Cheaper, faster and with more flexibility than public transport (except Megabus etc... I cant beat them on price) and that's about it.

I sympathise with anyone who wants to go fast, but nowadays going fast or in a big fat or fast car just seems like a waste of hard-earnt money to me, so I don't.

I've got an 07 C4 diesel and my computer tells me that my average mpg at the moment is 61.3 ... and my average speed is 26 :suspect: I have a 60 mile round trip each day on A-roads. I stick it on auto drive cruise control whenever possible and try to never exceed 57mph ... :)

sorry to resurrect (sp?) this thread, but I find I am only getting about 25mpg and wondered if anyone had any ideas on how to improve this,

Its a 1999 1.2 corsa, I have just had a new catalytic (sp?) converter fitted after it failed its MOT. It has been serviced recently, and I am always careful when changing gears, braking etc. I don't usually thrash it - and almost always stay exactly wthin the speed limits! - don't do motorway driving, so never go above 60mph.

I very rarely do long runs though, maybe the most I do at a time is 6 miles!

anyone got any ideas?

Here's one that needs a bit more thought. I drove into US from Canada and petrol there was in $/US gallon whereas in Canada it was $CAN/litre and I was paying in $CAN In order to try work out how much it cost to compare with here and in Canada I had to convert US dollars into Canadian dollars and pounds, US gallons into litres and imp gallons and kilometres into miles. By the time I'd reckoned it up and rounded figures up and down the numbers were completely inaccurate. No point anyway cos it didn't effect the price!

And you were probably in Mexico by the time you converted.....:D

They probably wouldn't were it not for the absurd system we have where distance is measured in miles, efficiency is measured in mpg but fuel is measured in litres.Indeed. It's high time this country dragged itself out of the dark-ages and went fully metric.

Short runs in cold weather use a lot of fuel as it runs rich to compensate for the cold air. For round town use those figures don't really suprise me that much, my 1.4 Rover was about the same

Just found a website which calculates the miles per gallon on your car...

its really good.

I get on average 32 mpg - mostly short journeys, I have a Corsa 1.2 - 9 years old. Anyone know if this is a good mpg? What's your mpg????

Thanks

Thats nowhere near correct. A civic type R does 30mpg. Are you sure you put the right details in??

Btw is urs a corsa 1.2 ls? cuz it should be around 41mpg and cost you around £125 a year in tax.

Good God, I've got to find something else to drive....I get 14.6 mpg. Granted, gas here costs a fraction of what it does there but it has gone up almost $2.00 per gallon in the last 3 years.

I think you'll find that more efficient cars will be in the pipeline...if not already cottontop. I think the lobbyists have had their day, they've held back fuel technology for far too long. It just isn't cool to be seen in a tidly car :D

The difference in price here and over there is almost insignificant when you compare mileage for mileage.

My last car over there wasn't too bad...about 30mpgish.

It does seem slightly low, but not vastly, considering the nature of your trips, and Olorin's post adds to that. Are you working it out by filling up, resetting the trip, driving for a week or so, then refilling and getting your figure that way? (not read the whole thread).

If you are sitting in traffic a lot on your short journeys too? Every few minutes of idling will cost a miles worth of driving.

The price of gas has dropped quite a bit in recent months. I remember just a couple of months ago paying $4.19 per gallon for gas and now it is down to under $1.80 per gallon. But I still want to get something with better mileage. The only reason I've held on to my current transportation is that I wont get squat for trade on it.

The smoking thing is a different matter altogether, Ash. There are many states that have banned smoking in all enclosed public places (i.e. restaurants, bars, etc). It might be a bit slow coming here as I live the state where "tobacco is king". The foundation of my state's economy is based on the cultivation and processing of tobacco.

Not seen you post for a while CT, Happy NY to you/OH/family. :thumbsup:

I know Cotton top, the smoking is a totally off topic and different matter. I just found it ironic/ or amusing at the time. :)

I wish I'd kept a receipt or two for the fill ups on my driving trip to see how I paid per gallon. I have no idea. And tbh I didn't care, it was so cheap. First time I filled up that beast, I had about £100 in USD at the ready, and it was only about $40. :hihi::hihi:

Good to see you, too, Ash. All is well with us and I hope the same for you.

When gas was higher (it was due to shortages from a closed pipeline during hurricane activity) it took me well over $80.00 to fill my tank (and I do mean tank...as in the size of the beast I drive). These days....its closer to $30.00. But I don't anticipate it will stay that way for long.

One thing I have noticed when looking at cars online with the OH is that our engines tend to me so much larger here. Average cars are 4.2 liter engines rather than the 2.something you have there. Guess the car industry has been reluctant to change the formula here since we've not suffered the same gas prices here as there.

Got my fingers crossed that things will change though. :D

On an American site I post on, many UK posters were saying that even at those high prices, it's still damn cheap, stop moaning. But the reality is of course, your economy, and day to day life can be heavily affected by fuel costs. If ours doubled as your post says, it would be unthinkable. It was bad enough ours being about 30% higher a few months ago.:gag:

Yeah, I think because fuel as always been cheap there, there was never much need for small efficient engines. Both my cars are 2.0l, and I consider that biggish for here.

I think the one I hired was a 4.8l. Gas guzzlingarama :o . Mind you it sounded beaut, reminded me of our old Rover V8 engines. :)

Diesel is the most expensive fuel we have for cars right now. I remember, back in the early 80's, my mom bought a car that ran on diesel because it was so much cheaper than regular unleaded gasoline.

These days....I'm glad I don't have a car that runs on diesel.

How does diesel compare price wise with regular petrol there?

Diesel is more expensive here now too. About 15 pence a litre I think. It was always cheaper in my younger days, but then as people cottoned on to it being a good option, it seemed to get more expensive. :suspect:

Diesel is running about $2.40 per gallon compared to $1.80 or less for regular unleaded here. I admit I know little about the differences between the two types....I always thought diesel was cheaper because it was less processed but I am sure that must be incorrect.

MPG figures are meaningless unless you state the nature of the journeys you make. Someone travelling on an A road will get a much better figure than someone travelling in town. e.g. My Picasso 2.0HDi averages just over 58mpg if I'm careful on long journeys, about 50mpg if I am in a hurry on a long journey, and a gnat's whatsit under 30mpg around town on relatively short journeys. I think these are really good figures for a gutsy engine like that, especially when I compare them to my old Montego 1.6 petrol, which did 51/44/19mpg respectively. I once got 61.4mpg on a trip to London, which is slightly better then the official figure for a constant 56mph, but I kept the speed down to under 60mph and maintained a light right foot.

My missus and I have the same cars, but hers is a 1.2 petrol Punto, mine is the 1.3 diesel.

It costs her about 14p per litre less for her fuel. So a full fill up costs her about a fiver less than me.

However, she only gets around 350-400 miles out of a full tank, whereas I get 550-600.

I know that more mpg can be got from longer journies, but that can't be helped! I'm always careful not to "thrash" it.

Is it because it is an old car (10 years old)

Is it because it is an old car (10 years old)Try running it on Shell V Power petrol, it is more expensive but it uses less, costs less per mile and it is better for the engine. I'm not sure whether it would work on Corsa but I've tried it on bigger engined cars and it is cheaper overall (5 to 8%) and I get better performance too. To work it out accurately you would need to virtually empty the tank first before filling it with V power so that it isn't diluted much thus upsetting your calculations.
