Supermarket Fuel vs Premium Diesel

1 never use supermarket fuel
2 every 4 tanks treat it to premium branded
3 give it a good thrashing regularly
4 this will stop things sooting up

Don't know if he was right, but that's what I'm doing on my new van, especially as we have diesel heating and it might stop that from gumming up ( give that a good full throttle burn occasionally as well).

Who only uses premium diesel rather than ordinary diesel?
Any difference do you think ?

Who don’t buy their fuel from supermarkets ?

Just a thought as recovery guy said he wouldn’t touch supermarkets fuel 🤷‍♀️

Your recovery guy obviously has plenty of money…😆

All my life always used the cheapest I can get and so do millions of other people…😎

I stay away from Morrisons diesel, because I was told it was biodiesel, don't know if it true or not, most fuel comes from the same storage facilities just the additives are different when loaded.

It's all biodiesel of some form, you can't buy anything else at the pump. It's what the E10 stands for... 10%

I've used the cheapest available for many years. Then read a number of articles in the last year (I can't recall what triggered it) and they mainly suggested having a periodic - maybe 1 tank in 4 - tank of the good stuff. Reportedly helps get rid of deposits, cleans injectors, improves performance and fuel efficiency and helps the engine to last longer. When I remember that is what I've done since.

Or just fit a blanking plate. 240k on original EGR

Over a million miles on supermarket fuel so your mechanic mustn't have shares in Tesco

After the way the supermarkets taised their prices in 21/22 and continue to, they will never get another penny for fuel from me.

Costco can be upto 20p a litre cheaper, and its premium, so more cetane etc.

And concur, Morrisons diesel caused a l/r disco to run awful, switched to costco and it ran much better.

I don't qualify for a Costco card ☹️

Independents raised their prices just as quick as the grunt supermarkets but were slower to drop them 🤷

The “qualification” criteria is most people, and even if you cant, borrow a card once for the fuel, keep the receipt and you can then continue to return..

Only checks that its actually your card is on entry to the warehouse.

I've been using supermarket diesel for well over 30 years in cars, vans and motorhomes without a problem, Fords, several Fiats, Honda and a David Brown tractor.
I put a bottle of Wynns adative in the motorhome perhaps once a year.
I did once fill with 'super diesel' or whatever it's called once but noticed no difference at all, assume it's for high performance, higher compression vehicles like BMW and Audi father than your avarage motorhome plodding along at under 3,000 rpm.
How often do you take yours up beyond 3,500 rpm?
I'm guessing that the main manufacturers who sell their wares to some 3rd world countries, Africa, South America, parts of Asia where the diesel may not get to the same standard as Europe, don't have many problems or they'd not be selling many

We joined Costco many years ago at the Malvern show. The cost of annual membership is easily recouped by the savings on fuel prices, especially for premium diesel.

I certainly wouldn't put E10 in a diesel it wouldn't like that at all😁

In France we get E85 15% petrol 85% ethanol, I have run my Toyota Rav4 on it for the last 5 years, the only issue is it takes a few goes to start if the weather is cold, at 60-70 cents a liter I have saved a fortune.

In Great Britain we have cars/lawnmowers than shouldnt run on E10 because of carburetor/injection issues mostly seals. Was your Rav specialy converted or is there a list of cars suitable for E85?

Apply for a WEX fuel card, currently 12p a litre off now to the end of March and always around 4p a litre cheaper than posted price the only downside is that is tied into ESSO so you are limited in where you buy.

Our car is a 2005, when I looked into it at the time, phyical issues with the fuel affecting joints seals etc shouldn't be a problem for any car later than about 2000, the main issue is that you need to change the timing, I did the conversion by buying a box online and fitting it myself, basically the box connected inline to the leads going to the injectiors to monitor and modify the injection timing.

All I really had to do is find a 12v supply and somewhere to mount the box, after fitting you do about a 20km drive on normal fuel while the box sorts itself out, then it ran fine whether you ran it on E5 E10 or E85, or a mixture of any of the above, the only issue is starting on a cold morning, but it has to be a morning close to freezing, even then it usually starts after 3 or 4 goes. Or you can do a mix of E5/10 and E85 to reduce the ethanol content, if it is a particular issue.

When I did the conversion there were a number of companies supplying boxes, but when there was a shortage of automotive chips, a few went by the wayside, including the company i used, as car manufacturers were given priority on delivery. The box cost me about 120€ at the time, but as E85 was half the price I got that back in a few tankfulls.

Your Indy repair guy was spot on with points 2,3 & 4… and if you follow 2,3 & 4 you’re OK with some (but not all) cheaper fuel…and more so if the Freelander is post- MY2011(?) when some setup changed… our Indy is ex-Land Rover and he’s told me this on at least two occasions I can recall…

I like the sound of Costco. I’ve checked and there isn’t a single depot in East Anglia, nearest is Stevenage. Not much use to me on that basis.

There's not one within 20 miles of me either.
Many people won't fill up at a supermarket because it's cheap but will go to a Costco because it's cheap :unsure:

Supermarkets cheap - ha ha really.

If costco could sell premium for 20p a litre cheaper than supermarket ‘cheap’ stuff, then it says only one thing, supermarkets are ripping you off.
