Petrol is not just petrol any more

Idiophreak

Might start a test on this. If I just note down the amount of miles per tank and the brand of petrol used, after a year, say, I should get a fairly representative average for each brand...

I've kept a record of my mpg. Worst was Shell, best was Tesco.
(1.8 petrol Zafira)

I would highly recommend the following site to track mpg and car costs:

You can get reminders when your MOT, service etc is due, work out costs per mile and compare your mpg to similar cars.

Hi,

Has any one noticed that when the likes of Tesco do a discount offer - the milage you get per gallon really drops off?

In my Honda JAZZ I usually get about 47 mpg - but when I filled up at Tesco on the 5p offer it goes down to 41mpg. I've noticed this several time. (when I filled up at a non supmarket petrol station it goes back up to 47 (plus) mpg.
This is for the same journey to and from work.
:money:

What kind of discount offers ?haven't noticed any yet at my Tesco.They are always dearer that ASDA or Morrison's and Tesco admit they only match the competitors if they need to.

In fact, what has actually happened, is we've all - well some of us - been brainwashed to think the superstores have given us & still are, lower priced fuel.

In reality, all that's happened, is the vast majority of filling stations have been put out of business, by them.

This has enabled the margins to be maintained, on fuel, cheaper & easier for fuel companies to beliver in bulk, but actually INCREASE the amount of fuel we'd need to use, 'cos we now all travel a greater distance to fill up, by patronising the superstores.

They dictate the price & no, there aren't any REAL offers!! 5p litre off, if you spend £50 instore!!? Maximum 100lts each sale?? Not many vehicles have that capacity, anyway, so even a virtually empty tank, might get 50lts. So they're giving you just over £2 once the VAT is accounted for.

Generous, or not!!

OP's post reads quite funny, really

Surely the fuel you get if you don't use a voucher is the same as the fuel you get if you do?

Or do you go up, give them your 5p off voucher and when they scan it through, some little elves get to work, drain some of the fuel out of your tank and top it back up with water...Just seems unlikely

JPS

I've had several debates on this on online forums and it is clear that Tesco petrol does not agree with some cars, it's as simple as that - depends on how fussy your engine is. It made my car a few years ago dreadful to drive, caution lights kept coming on as it was affecting the O2 sensor! - put Shell in and it was fine! Tesco Super Unleaded 99RON however, is actually one of if not THE best ironically and I use it in my Clio sport - but wouldn't touch Tesco RON 95 ever again! I'd always recommend Shell as they are usually the same price as Tesco (if not cheaper sometimes) and the quality of their petrol is always up to scratch.

Exactly ,thats why I was querying what 'offers' as I thought the Op couldn't be refering to the 5p discount.

Maybe its the fact you have £50 worth of shopping in the boot for part of the journey so your consumption is going down as soon as you leave the pump from the heavier load!

Funny enough we were having a chat to someone about this very subject a few weeks ago
We have a fiat sedici, [diesel 50 litre tank.]


When using total or texeco fuel, the car runs far better


When we go to Tesco or other supermarkets [as its cheaper] the car jolts and it chokes and it don’t go as well as it does on branded fuel


We had it serviced last week, the filters were filthy, and the turbos all clogged up the whole lot had to be cleaned [the car is just about one year old]


The guy that did it for us asked if we used supermarket fuel in her, we said sometimes, he said that high performance diesel cars should not use these supermarkets at all.


Then we spoke to others about the supermarket fuels, and they all said the same or similar things, mileage is down a little, and it is just not running like the car used to.


Then someone told us that the branded garages go in first to get their stocks, they grade it somehow, not sure how, but the fuel that is of a lower grading than they would like is left behind for the supermarkets to pick up, which is why supermarkets have it a little lower in price, I am not sure if this is true, I do not understand it as it goes into car bits and then becomes a little complicated to understand, but the garage guy said to us to keep the car in tip top condition, and to keep her running smoothly without any hitches, to make sure we only use garages such as shell, texeco and total, and not to use supermarket fuel anymore, no matter how much cheaper the fuel is. He stressed again that the fuel they sell can be compared to the left over’s that someone else does not want



Not to sure at all, I always thought fuel was fuel, until we have spoken to people, and then this thread, we wont touch supermarket garages anymore, the guy who serviced our car said he had not seen so much muck before in a car that was not that old.



Could be something in it, and maybe something for watchdog to have a look into? It would be interesting anyway to see what they come up with.
