Best place to fill up my car?

I use Shell fuel for my car. There is a noticeable difference in the way the car feels when I put that stuff in. The car feels like it has more toque and I get much better MPG as well compared to Sainsburys and BP fuels.

I will SO bet that a proper blind trial would reveal absolutely zero difference.

Especially on the 10yo Seat.

Perhaps it's been upgraded? To an A3, or maybe M3.

I pretty much always buy branded fuel because I drive past petrol stations on a daily basis. My nearest supermarket petrol is a 25 mile round trip away at a supermarket I wouldn't use for shopping.


The cheapest petrol is usually the petrol you don't have to drive out of your way to get.

Possibly for some .I use Petrol Prices email that lets me know local pricing .Out and about if i see bottom of price range then i fill up if under half a tank left .

Let's say your car takes 50 litres of fuel, and does 45mpg.
At £1.10/litre, you're spending approximately 10p/mile on fuel alone.
1p/litre difference adds 25p to a half-tank purchase.

If you have to go more than 2.5 miles out of your way to buy that half-tank of fuel, you've just spent more than you saved.

I don't need an email to read the signs on the three local stations, all of which I pass often enough to know which is cheapest.

For my car:

• 50 L tank means a 50p saving per p/L difference.

• 4.6 L/100 km = 0.046 L/km efficiency means each km costs 5.06p.

So I'd have to drive 10 km for a 1p/L difference to not to be worthwhile. However, the real world is much different since most journeys to/from fuel stations would be city driving and thus less efficient than average figures, plus there's the time involved (particularly at peak times), and the fact that rarely is a full tank actually required. 5 km seems a more reasonable estimate, although I really could never be bothered - the two supermarkets near me are often 2-3 p/L cheaper than the Shell, Esso, and BP but both are in totally the wrong direction (compared to work) and I'd have to go through a town centre to get to them. So basically I wait until I'm shopping at the supermarkets to fill up.

Thank you for agreeing almost exactly with my figures, albeit with a measure of economy that isn't used in this country.

Personally find the cheapest fuel in your area and buy that. I use the petrol price app when ever I'm going any where to see how fuel prices compare and the difference can be quite big. Recently saved 6p a litre compared to my local supermarket than one in Milton Keynes where I was going. Made sure I had enough fuel to get there and then filled the tank while over there. 40 litres of fuel saved me £2.40. Even looking on the app now a 10 mile radius of my home has 3.2p litre difference.
