If you've filled up your car recently, you probably didn't need anyone to tell you that petrol prices have gone through the roof. But just in case: the average litre of unleaded is now sitting above 155p, diesel has smashed past 191p in some places, and certain London forecourts are charging north of £2 a litre. A full tank of diesel now costs close to £100. Lovely.

The culprit? The ongoing fallout from the Iran conflict has sent oil prices spiralling, and drivers across the UK are picking up the bill. It's the kind of news that makes you want to leave the car on the drive and just walk everywhere — except it's April, Storm Dave just battered the country, and walking to the Spar or the Coop in horizontal rain isn't anyone's idea of fun.

But here's the thing: there are genuine, practical ways to cut what you're spending on fuel — and AI can help you figure them out, even if you've never used it before. No apps to download, no spreadsheets to wrestle with. Just a quick chat with a free AI tool like ChatGPT, Gemini, or Claude, and you'll have a clearer picture of where your money's going and how to keep more of it.

Start With What You're Actually Spending

Before you can save money, you need to know where it's going. And most of us have only a vague idea of what we actually spend on fuel each month. We tap our card, wince slightly, and move on.

AI can help you get a proper handle on this. Open up a free AI chatbot and type something like: "I drive a 2019 Vauxhall Corsa petrol. I do about 120 miles a week, mostly school runs and commuting. Roughly how much am I spending on fuel each month at current UK prices?"

The AI will estimate your monthly spend based on your car's typical fuel economy and current pump prices. It's not magic — but it's a lot quicker than digging out every receipt from your glovebox. Once you can see the number in black and white, you've got something to work with.

You can go further, too. Ask it to compare what you'd spend if you drove a more fuel-efficient car, or a hybrid, or even an electric vehicle. You might be surprised — or you might confirm that your current car is fine and the real savings are elsewhere.

Find Cheaper Fuel Near You

Not all petrol stations charge the same price — and the difference can be significant. Supermarket forecourts like Asda, Sainsbury's, and Costco are often cheaper than branded stations, but it varies by area.

You can ask AI to help you think through this strategically. Try something like: "What are the best ways to find the cheapest petrol near me in the UK?" The AI will point you towards useful tools and apps you might not have known about, and help you figure out whether it's actually worth driving a bit further for cheaper fuel (spoiler: sometimes the extra miles cancel out the saving, and AI can do that maths for you too). Bear in mind, if you live in Alston - 20 miles from a supermarket petrol station it might cost you more because of the fuel you used getting there. The AI can work that out for you too. It is always worth shopping local if you can!

It can also help you decide whether a supermarket loyalty card or fuel reward scheme is worth signing up for. Just describe your situation and ask — that's genuinely all there is to it.

Get AI to Plan Smarter Journeys

Here's where things get really practical. A lot of the fuel we burn isn't from big trips — it's from badly planned little ones. Popping out for milk, then going back out for the school run, then nipping to the post office. Three separate trips that could've been one.

Ask AI to help you batch your errands. You could type: "I need to go to the supermarket, the post office, the vet, and pick the kids up from school at 3:15. What's the most efficient order to do all of this in one trip?"

You can even ask it to suggest which days to combine your errands, or whether certain trips could be replaced altogether — online shopping instead of driving to the retail park, for instance.

Check Whether Your Driving Habits Are Costing You Extra

This is a good one. Most of us have picked up driving habits over the years that quietly burn more fuel than they need to. Heavy braking, speeding up too quickly, idling in the school car park with the engine running, carrying a boot full of stuff you forgot was in there.

Ask AI: "What are the most common driving habits that waste fuel, and how much could I save by changing them?" You'll get a clear, plain-English breakdown of small changes that add up over weeks and months. It's the kind of advice your dad probably gave you when you passed your test — except AI won't also tell you off for not checking your tyre pressures.

(Although, in fairness, you probably should check your tyre pressures. Under-inflated tyres genuinely do use more fuel. AI will tell you that too.)

Work Out Whether Going Electric Is Actually Worth It

With fuel prices this high, plenty of people are wondering whether it's finally time to make the switch to an electric or hybrid car. The trouble is, it's genuinely confusing. Upfront costs, charging infrastructure, electricity prices, range anxiety — there's a lot to weigh up.

AI is brilliant at this kind of comparison. You can say: "I currently drive a 2017 Nissan Qashqai diesel and spend about £250 a month on fuel. I mostly do short trips around town with the odd longer drive. Would switching to an electric car save me money? What should I consider?"

The AI will walk you through the key factors: how much you'd spend on electricity versus diesel, whether your driving pattern suits an EV, what government grants might be available, and what the total cost of ownership looks like over a few years. It won't tell you what to do — but it'll give you the information to make a decision that's right for you.

Try This Prompt

Here's a ready-made prompt you can copy and paste straight into any free AI chatbot. Just fill in the bits in square brackets with your own details:

I drive a [type of car, e.g. 2018 Ford Focus petrol] and I spend roughly £[amount] a month on fuel. I drive about [number] miles a week, mostly for [commuting/school runs/errands]. Can you help me work out where I could cut my fuel costs? Please suggest practical ways to reduce what I'm spending — including driving tips, journey planning, and whether it's worth looking at a more fuel-efficient car. Keep it simple and in plain English.

The Bottom Line

Petrol prices are high, and they might stay high for a while. You can't control what's happening in global oil markets — but you can take five minutes to ask AI a few smart questions and find out exactly where your money's going and how to claw some of it back.

You don't need to be a tech person. You don't need to download anything. You just need to type a question the same way you'd text a knowledgeable friend. Give it a go — your wallet will thank you.
