Your awareness of petrol prices?

How aware are you when you fill up your car if what it's costing you?

Talking to a family member yesterday, who uses their car to travel round for work,and they said they just fill up and don't bother really keeping track of the cost.

Surely if self employed, you'd need to know as you mean need to adjust your prices to your customers you visit.

Do you just fill up and pay or are you actively tracking the price.
AIBU to assume, someone who is self employed and visiting customers would be monitoring the costs?

I’m less worried about cost than I am about availability. On a usual week we don’t drive much but we have a couple of long-distance trips coming up and I’m slightly concerned about being able to fill up en route.

Always look and keep a log of fuel amount, mileage and costs, it's really high at the minute if anyone hasn't noticed!

I have to drive 240 miles every weekend so I pay attention - slow creep up is worrying but not as bad as it was a few years ago. I am very happy to have a couple of weeks off the long journey so less need to refill but worried it will be worse next month when the tankers that would have left are missing in port.

HappyMuma · 29/03/2026 19:35

I know I can’t get by without filling up so I just do it without checking the prices. I think it’s the same for most of my family/friends

Pinklemonade1 · 29/03/2026 19:29

It's gone up 40p a litre in just a few weeks round here so I'm very aware!

Tracedom · 29/03/2026 19:23

Why bother to post, just to explain you do minimal mileage or drive a hybrid so the rising price of petrol doesn't affect smug little you?

Catladywithacat · 29/03/2026 18:53

Usually no but I noticed today as I pass a shell, Tesco and bp that bp was lower than Tesco

Sheknowsaboutme · 29/03/2026 18:47

Very. I fill up on payday then top up when down a quarter. I use a local independent retailer. Not supermarket

BiscuitsCheeseBiscuits · 29/03/2026 18:41

I'm very aware and worried about it. Was already struggling financially and this isn't going to help. I'm also worried about the shortage that seems to be happening. Without reports in the press I've seen garages run out of fuel (both unleaded and diesel). Feel it's going to get worse before it gets any better.

Wish I could just absorb the cost and say well I have to do it anyway.

voidcatsarethebest · 29/03/2026 18:36

I have a vague idea but I use maybe half a tank a month if that. My commute is an 8 mile round trip

Silverfoxette · 29/03/2026 18:33

I’m going to be asking if I can work from home where possible to save money travelling. For example we have no customers in our place this week so I could easily work from home. I’m going to cut back on unnecessary journeying

I live in London. Cars are a waste of money.

mit123 · 29/03/2026 18:26

I am aware - yesterday I was visiting friends and the diesel went up by 5 pence during my four hour stay - absolute joke

clary · 29/03/2026 18:18

I always know where the cheapest petrol is. It varies a lot too.
There is a small local garage I go past a lot which is often very competitive so I use that. Also a garage on the way to work that is often a good price.

We have a Costco card and the petrol there is always cheaper than anywhere else. But it's not on my usual round so I don't fill up there that often.

I recall saying to a colleague that I shopped around for petrol and they said "there's no point driving miles out of your way just to save a few pence.” well obviously not. I don't do that. If I am going past where the Costco is (about once a fortnight) I will fill up if I have time (often a big queue).

I should add I do a lot of driving – like 20k a year including a 50-mile round trip for work most days. So I fill up my baby car once or twice a week as a rule, hence being super aware.

Just for info – unleaded at Costco yesterday 138.9, nearby usually cheap Jet 145.9, cheapest supermarket nearby 141.9, very local Shell 154.9. So if you are using 40L a week that's a possible difference of more than £6 without going anywhere near a v £££ motorway services.

Surprised so many ppl don't check but maybe if you only fill up once a month you can afford the extra fiver.

I don't really pay attention, obviously I am aware it's increasing but my car is used for work and back with very little mileage and a small engine.

Apologies..I didn't mean to quote you 😀

Lincslady53 · 29/03/2026 18:10

I have always been aware. Wecran a business and always kept an eye on prices, if you buy 59 litres a week, and pay just 2p a litre more than necessary, that is £100 a year thrown away, out of taxed income, so £135 to £160 pretext. I woukd rather have in my bank than the petrol companies. I would drive out of my way, but would certainly know the cheapest on my routes. The petrol prices app is useful. Recently gone electric and a 150 mile trip has cost us £3.00 of electricity, compared to over £20 in petrol. To me, spending more than you have to, because you can't be bothered to check is just throwing money away.

I'm painfully aware. I have a mini and it's costing an extra £10 to fill up. Which I can't afford.

For all the people gleefully saying fuel prices don't affect them as they don’t drive...wait until everything which is transported starts to increase. You'll be affected then.

ContentedAlpaca · 29/03/2026 17:58

I fill up roughly once per week. I use the more expensive E5 rather than E10 since an expensive fix later when I discovered it is better for my engine.

There's no point getting my knickers in a twist over the cost as I'm stuck with it.

Harmonypus · 29/03/2026 17:50

Not self-employed, not visiting customers, etc, but painfully aware of petrol costs, which is why I signed up to Costco 2 years ago, their fuel is general 5-6p per litre cheaper than the supermarkets, and it doesn't hurt that there's a Costco about 3miles from home.

2dogsandabudgie · 29/03/2026 17:39

I never used to check how much diesel was until recently with the Iranian war. I filled up about 2-3 weeks ago and it was £1.48 a litre. I looked on Friday and diesel is now £1.70 a litre. This was in Tesco which is usually one of the cheaper places. Luckily I don't use my car much.

FoolOfShips · 29/03/2026 17:26

DH is the car owner/driver but I pay for petrol - we know which are the cheapest places near us. We have a very small car and two default options - top up with £20 when it's below half full or 'fill her up' if we have a long journey planned - 'fill her up' was costing £35 to £40 before recent price increases (from one or two bars) - we're going to have to do 'fill her up' again this week so I am expecting it to be more expensive.

Waitingfordoggo · 29/03/2026 17:20

We’ve just paid £1.85 a litre for Diesel on our way back from visiting friends who live a couple of hundred miles away. Very grateful that we only have to use this car infrequently and only for leisure trips/holidays (so if things gets really bad, we’ll just have to cut down on leisure trips)

DH works at home and I drive an electric car. The COL is kicking us up the arse in multiple ways but at least car fuel is not one of them.

Peony1985 · 29/03/2026 16:55

@DefiantRabbit9 Both people I know with epilepsy get their partners to drive and get their cars cheaply through the mobility scheme. Theirs are brand new and fuel efficient.
My privilege gets me a reliable 20 year old Volvo that however costs £65 a week to fill up just to get to work.
