13p a mile in fuel to run my car - do you know what yours cost (it's a simple calculation)

Diesel is £2 a litre, Luckily my car is economical - 67 mpg.

If you want to convert to pence per mile - then take the cost of fuel (in pence), multiply it by 4.54 and divide by your cars mpg.

(200 *4.54 / 67)

(Obviously mpg can vary when in towns vs long drives )

30 mpg @£2 a litre is 30p
60 mpg @2 a litre is 15p

You can see how journeys can add up - and how some people who have to drive for work are struggling.

Around 22p a mile - that means it costs about £13.50 a day for me to travel to work! Thankfully I'm going to only 3 days in the office from august.

Between work, looking after my disabled mother & any other journey (food shop, visiting friends etc) I'm using a full tank each week.

It's making me think about new jobs - and their location. A lot of the jobs I want are a much further commute - so it would have to be a decent pay rise.

It's a real issue.

Mine worked out to 13p too. So 2 miles to work and back. 26p each day. Bit more on grocery day.

Interested in this thread?

26p I think .

Tank was just under the half way line thurs so thought I'd fill up £96 later Shock couldn't understand it though because it's not £192 to fill a whole tank , very bizarre

ifonly4 · 03/07/2022 20:45

When we've driven 400-450 miles on our full tank, we've always felt it needs a top up, so well aware we're talking 23p+ per mile. Without even trying that much we're cutting back on travel, food shopping done on foot as one of my jobs next to supermarket, going for a walk instead of day trip.

KarrotKake · 03/07/2022 20:47

18p/mile

£5.40 a day to work.

rumred · 03/07/2022 20:47

Thanks @cakeorwine I've never been able to work it out properly before

IncessantNameChanger · 03/07/2022 20:48

21-26p per mile calculated by cost to fill up and how many miles since resetting the trip mileage. Worrying really. Do diesel is much cheaper to run

We're planning a driving holiday so I am trying to estimate the fuel cost.
Need to look at tolls though.

I can get a much better mileage by driving more slowly (but that would take much longer) A French autoroute at 56 mph might be seen as a bit boring.

About 18p per mile (petrol not diesel).

I have a 65 mile round trip daily commute and am spending around £300 a month on fuel at the moment. I try not to use my car at the weekend.

boydy99 · 03/07/2022 20:58

Ours must be around 30p per mile 😱 3l diesel estate, but luckily we don't do a lot of mileage. DH cycles to work and I wfh although I'm on mat leave at the moment, so we have almost no commuting costs, just general running around locally.

If I lived only 2 miles from work I would cycle. However, my commute is 24 miles each way, most of it on motorways.
My journey works out at 24p per mile. Luckily I WFH most of the time.

Honestly not trying to sound smug but I hear so much against electric cars so this is the counter argument - my 6 year old Leaf (that cost me £7k last year - so not the £30k that people usually say they cost) is 4ppm so the equivalent of 227mpg.

SingingSands · 03/07/2022 20:59

I'm going to sound really dim but how do you work out the mpg of your car? And where does the 4.54 figure come from?

Sorry - I'm really terrible with numbers Blush

alwaysmovingforwards · 03/07/2022 21:00

About 38p

True - the cost of electricity is increasing though but the cost per mile is good.

My car tells me the mpg.
The 4.54 converts from miles per gallon to miles per litre ( there are 4.54 litres per gallon)

If you fill you car up, do some miles, and then fill it up again - you should be able to work out how many miles you did and how much fuel you used (in litres)

So you don't need the 4.54 bit

Averaging 13.5 over a full tank in a 2005 Prius that cost just under two grand a year ago. This calculation doesn't take into account all the rest of the costs of running a car, of course. But interesting to see what it's costing people. My commute is 36 miles a day. Public transport is not an option.

Very true - we have an economy 7 tariff so at the moment it costs 16 pence per kwh - if that doubles it will be 8 pence per mile

SheWoreYellow · 03/07/2022 21:10

What is your car! Ours is so much worse than that.

OnceAgainWithFeeling · 03/07/2022 21:11

50l tank. Super unleaded £2.10 a litre. Get 160-180 to the tank so 58-66p per mile.

AlohaMolly · 03/07/2022 21:17

I googled my car to see what the average mpg was, so not particularly accurate, but an average nonetheless. I did the calculation mentioned in the OP and it came out as 32p a mile. That can’t be right can it? It is an 02 plate but still?

AlohaMolly · 03/07/2022 21:20

Based on that calculation, it costs me £30 in Petrol just to get to and from work a week. For a four week month, I am spending £120 on petrol for a job that pays me (take home pay of) £921 and that’s without supermarket runs and taking DS to swimming lessons etc. FML.

If you switch to Octopus Go you could get 7.5 p for 4 hours at night. My i3 costs me 2p per mile. We have solar panels which provides most of the rest of our electricity. Not an option for all, but they are paying for themselves very quickly at these rates.

It can be right.

Some cars aren't very economical and fuel is expensive.

What car have you got?
