When see things like this, I always think of the Chinese proverb

"An inch of time is worth an inch of gold, but it is hard to buy one inch of time with one inch of gold"

Which always says to me that its not worth it just use the quickest option

Take the example drcongo posted:

"Yesterday I had to drive to a nearby town, just 20 minutes away, and noticed that every single petrol station there was a good 5p per litre cheaper than my town. I might plug this into a map."

Assume he uses 30 litres a week (high end of average UK usage) that's £1.50 per week saving but assume the extra miles use half a litre, that takes about 65 p off the saving (ill not go into wear and tear) over 30 years of work 50 weeks a year this means a saving of £1,275 over 30 years ... sounds a lot but

20 mins away - this assumes 40 minutes per week over 50 weeks is 2000 minutes, and over 30 years 60000 minutes. Now assume you are awake for 16 hours a day this equates to 62.5 days of free time - more than two months of awake time

so as the saying goes... which would you prefer £1,275 saving or 62.5 days of time

I've also wondered about whether to fully fill my tank or drive on a small amount so that I'm not using fuel to carry fuel. Do you know of any metrics on that?

you can probably work it out but you have to make a lot of assumptions :)

Ultimately how much is your time worth? in the example given drcongo's time is worth £1.28 an hour.
