You probably think you know how much fuel costs. Where I live, diesel is around £1.40 a litre right now. So, in basic terms, it’s £1.40 a litre. But how much is that in real terms?
Well, while out walking the dog, I figured out that it costs me £3 a day to drive to and from work. And that scares me, because I don’t live that far from work, as it takes around half an hour to cycle there every day – and that’s when I’m taking it easy. I have managed to get there in 21 minutes when I was actually trying.
So, how is it £3 per day?
Well, first we work out how much a gallon of fuel is, because cars tell you how much fuel they go through per gallon, by way of miles to the gallon. So, if fuel is £1.40 a litre, and there are around 4.546 litres in a gallon, then £1.40 x 4.546 is £6.27 per gallon.
Next we work out how many miles to the gallon my car does. Apparently around 40 right now. That’ll probably / hopefully improve soon, but it’s a close enough figure to be getting on with. If I can go 40 miles per gallon, and it costs £6.27 for a gallon, then 40 (miles) ÷ (£)6.27 = 6.38 miles per £1.
It’s about 9 miles to drive to work; far less on my bike, at around 6.7 miles. 9 miles there, another 9 back, 18 miles. 18 ÷ 6.38 = £2.82 fuel per day. Add on 18p for when I’m sitting at lights idling, and you’ve got £3.
Clearly, this is a rough bit of calculation, but it’s not going to be far away. £3 per day may also not sound like much to some, but it’s a hefty bit of cash when you’re going 5 days a week. And if you can save that cash by cycling to work, then you’re doing yourself two favours in one, by saving cash while getting / keeping fit.
It’s a no-brainer.
