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 almost never go out of my way for fuel, because as you say, it's rarely worth it once you factor in your time (never mind the fuel spent).
But it's still useful to know about price variation so that you can plan ahead. I regularly drive past several different petrol stations, and if I know that one of them is usually cheaper or usually more expensive then I choose to use or avoid it, or to decide that I'll fill up tomorrow when I'm going that way rather than today at a more expensive one.
And that'd be more useful built into satnav, so that if I know I have to fill up somewhere along my route then I can pick the cheapest place, since there's no real time cost to any of the options compared to each other.
totally agree, technology could make this much more cost effective (or time effective). what's the best use of my time versus the cheaper option..
It's interesting running the numbers though. e.g. if it only take 10 minutes to get cheaper fuel, how much cheaper does it need to be for your time to be worth more than the UK minimum wage (£12.21 for adults over 21)
based on my maths (from above calculations) it needs to be about 7p per litre cheaper to justify the extra 10 minutes and for your time to be worth more, per hour, than the minimum wage.
Also depends on the size of your fuel tank and how full it already is. The time taken to refuel is (almost) the same regardless, but if you've got a 40l fuel tank vs a 70l one or you're only half-empty then it's going to be less worthwhile.
7p cheaper for 10 minutes works out at about minimum wage if you're buying 30 litres, but with a bigger car you could easily be buying twice that, which works out much better.
Although of course you also need to factor in how much fuel you burn driving to the cheaper place, and the extra wear and depreciation on the car. If you take the HMRC standard rate of 45p/mile (which was meant to cover all of that kind of thing, but hasn't been updated for years) then even going a few miles out of your way quickly ends up costing more than it's likely to save.
Driving somewhere to fill the tank 5p/l cheaper probably waste of time but unless all your trips are very short you usually can find a petrol station along a commute roue or along the route of a long leisure trip which is cheaper than one closest to your home. When you see prices in your navigator it's much easier to do.
As someone who waits until my tank is almost empty, to visit Costco one per month for a fill-up, despite it being 5 miles away, I understand your point.
However, I think (and hope) the point of this service is that by being public, it'll drive prices down for drivers.
I drive 10 miles round-trip once per month to save what I guesstimate is £5 on a tank of fuel, then spend £100-300 in the Costco store while I'm there. I'm not the target audience, but I hope that for those who drive regularly, or for a living, this can help route them to where they can get the best prices as they're passing by.
Driving 40 minutes to save 5p might not be worth it. What does make more sense (at least where I live) is to go to the petrol station in the late afternoon or evening instead of the morning hours. The intraday price span on most regular fuels is usually 10 Euro cents per liter. Weekends also tend to be cheaper.
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?
I haven't made any calculations, and it's more a hunch, but considering you usually need to remove hundreds of KG in order to make an impact on how much fuel is being spent, 40-50L of gas (~40KG difference between full and empty maybe?) would have an marginal effect on how much fuel is spent to carry a full tank vs 10% filled tank.
Besides, with a smaller tank, you'll make more trips to tank it, and also have less choice to go to gas stations that are further away but have cheaper price. Then again it becomes a question of "Do I want more time or more money?", back to square one :)
Edit: Also, someone correct me if I'm wrong, but doesn't the fuel pump use fuel itself as a coolant or something? Never investigated myself, but some car-knower once told me that running the tank on low always isn't good for the fuel pump, or something like that. If that's true, running with 10% of the fuel would mean more maintenance too, potentially removing any savings in the first place.
Yeah, fair enough, I think what he mentioned though, wasn't just about fuel going through the pump being used as coolant, but some extra process that only happens when you're not running below say 10% or whatever, an extra cooling process that only runs when you're not low on fuel. Maybe I misunderstood him though and it's just about the liquid passing through.
I think the fuel passing through is the only method that could be used to cool, the volume of fuel required is presumably constant, regardless of how much fuel you have left, so the amount passing through the pump should be the same until you run out.
On a related note, my car has a fuel heater, to pre-heat the Diesel before it hits the engine, I assume this is typical in modern cars, but using the fuel as a coolant would presumably contribute positively to this desire for warmer fuel entering the cylinders.
If your priority is the journey to fill a car with fuel and time spent doing so, surely just buy a Battery Electric Vehicle and then this problem evaporates because it just plugs in like every other appliance you own rather than needing a trip to a fuel station.
Shopping around for the fuel of an EV you can do from a web browser, oh hey, Octopus have a good deal for night charging, click click done.
What are the price variations like over short distances?
In the US gasoline short distance price variations are ridiculous. I've seen it where one station was $3.50/gal and another station on the same main road just a 30 second drive away was $4.30/gal. These two stations almost always have a large difference like that. This kind of large difference over a small distance is common all over the country.
Yet a surprisingly large number of people will always choose the more expensive station, even if they know about both of them (and the other stations with prices consistently in between that are also about equally close). There's nothing about the layout of the town and traffic patterns that make the expensive station more convenient, or make it easy to find. All these stations are about equally busy so it is not like the expensive one is faster. The less expensive one even has a way better convenience store.
This is one of the higher gas price states and people are constantly complaining about how much it costs to fill up, and when I ask complainers about where they buy gas it is often the expensive stations.
Many of them think that if they don't buy at the expensive station it will be bad for their car. Different brands add different detergents and additives that fight clogging and build up of deposits in your engine and fuel system.
However in 1995 the US got a federal standard that all gas has to meet, and then in 2004 several major car makers developed a standard they called "Top Tier" which is about 20 times more effective than the federal standard. Most major gas brands now sell only gas that is certified to meet the Top Tier standard.
Most testing has found that going for something beyond Top Tier doesn't really have a significant benefit for most people. For nearly everyone the best approach is:
(1) Avoid gas that is not at least Top Tier. Generally the only places that sell gas that isn't at least Top Tier are grocery store brands and maybe some convenience store brands. The savings with those brands is usually only a couple or so cents a gallon compared to the least expensive Top Tier brands (ARCO, Costco) and your car will perform better (including improved mpg) and need less maintenance.
(2) Buy the least expensive Top Tier or above gas that is convenient. You aren't going to notice any difference in performance or maintenance if you pay extra for some brand's particular proprietary blend.
I guess the question is how will it be enforced and what would the penalties be for reporting inaccurate or outdated data?
Companies do not understand "must" unless it's accompanied by a proven threat of sanctions that outweighs the profits made by breaching the regulation. The GDPR is a good example of plenty of "musts" and theoretical fines but lax enforcement means it's always more profitable to breach it than comply.
Looking at that document, this regulation is dead on arrival. Enforcement is contingent on the aggregator noticing the price discrepancy, giving the seller many opportunities to rectify the situation without a penalty (if we assume every step gives them 30 days to respond, we're looking at ~5 months before a financial penalty becomes possible), and even then, the regulatory "may" impose a financial penalty, meaning it isn't even guaranteed.
You know what would immediately resolve this problem and prevent non-compliance? A reporting system where any citizen can submit evidence of a price discrepancy and upon validation gets a 1k payout from the government who then recovers it via a fine. This would make it sustainable for anyone to act as an "auditor" or even do this as a business.
Of course, the reason it isn't done this way is because it would be too effective, where as this current iteration gives the appearance that something is being done while having no impact in practice.
This is a great innovation and I'm sure in time it'll become a useful source of information. There are some edge cases of course.
If you live on the Irish border, you'll have a choice between getting your petrol on the UK side, or the Irish side. For about 20 years, petrol was cheaper on the Irish side, causing a bunch of petrol stations to spring up just over the border, attracting drivers from the other side with cheap prices and good exchange rates.
In the last 10 years or so, the position has reversed. Petrol is now roughly cheaper on the UK side of the border, or at least not worth making a special trip for.
There's even a petrol station in Belleek mentioned here[1] that straddles the border and apparently has or had pumps on both sides.
It doesn't mention any filters beyond batch number and effective start date. They're definitely storing the lat-lon information though, so it would be nice to do area-based queries, especially if you're building an app with a map view.
This is great news. There used to be a handy email newsletter that did this, but then when everything became "apps" the newsletter disappeared in favour of an app, which then became a premium paid service only.
It's missing closing the circle with one of the users of the premium paid only service to start their own newsletter because they got tired of the paid product. It's only a matter of time.
I wouldn't look forward to having to do that every time I changed prices!
I wonder how many small independent stations are there these days? Almost every one I see is either in a supermarket, a big chain like Esso, or a smaller chain like Harvest.
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.
The variation in even a couple of miles can be pretty big. I almost never go out of my way to visit a cheaper petrol station because that's usually a false economy, but there are definitely some local places that I favour or avoid because they're almost always cheaper/more expensive than the surrounding ones.
I had to give up Waze over xmas because it refused to give me the 1 hour, straight down the motorway route, and instead tried to send me a bizarre route that would take 2.5 hours. Switched to Apple Maps and haven't gone back, though I do miss the fact that Waze shows you your current speed.
More unnecessary meddling, this causes price convergence so anyone living close to a typically lower cost source of fuel is going to have an almost imperceptible increase in relative cost.
They certainly love spending taxpayer money on nothing don't they.
In the above model prices converge on a mean, reducing the potential savings for those that price really matters (the poor are the ones most likely to check existing price discovery sites), thus it's regressive - the government are either seeing it as an opportunity to marginally increase tax rake, or more likely are oblivious to the externality of the poor bearing the burden.
Which model? Tested how? Are the poor the most likely to check existing sites?
This is not a new sites. Its making data more available so sites and apps will have more accurate data. This is most likely to benefit those who are willing to trade convenience for lower costs.
This is a funny take, because we ostensibly assume 'perfect information' when we extol the virtues of capitalism. It would appear the government is supporting capitalism with this particular initiative...
We don't assume perfect information, or rather - it exists already in an unsanctioned form for those that seek it (usually those to whom price is sensitive).
Until this we assume marginality holds true and price dispersion has a benefit in society that we unwittingly enable.

so as the saying goes... which would you prefer £1,275 saving or 62.5 days of time
>so as the saying goes... which would you prefer £1,275 saving or 62.5 days of time
Just want to say, nothing wrong with doing that. Everyone has different priorities. I just hope most wont have to do it.

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.
Unless you're driving a lorry with a 120L tank, it's negligible. We're talking like, 100 mL per 100km.
If your priority is the journey to fill a car with fuel and time spent doing so, surely just buy a Battery Electric Vehicle and then this problem evaporates because it just plugs in like every other appliance you own rather than needing a trip to a fuel station.

Well that saved me from trying to work it out, thanks!

You didn't factor in the amount of taxpayer money spent on creating the website and the ongoing costs of running it.

I wonder if the CSV is supposed to list all petrol stations, as currently it only has 4 with city==Edinburgh.
Edit: after asking AI about this I would say the CSV is pretty useless as a comprehensive source of info on UK fuel prices.
It’s only just been launched. AI isn’t a great way to find out about brand new things.
Apparently although it is a requirement to upload data from today, there's an effective grace period of 3 months (sorry - got that from AI).
There is an app called 'PetrolPrices' which seems to have a pretty complete price database. It's much better than this government API so far.
