Hi all, I did a search but couldn't find anything conclusive on this.
Quick background for posting this: I got a text saying my personal fuel card from Fuelpecker has now changed to WEX ESSO and there was a link to sign up. Naturally sceptical, I contacted Fuelpecker and Googled to see if there was something to confirm this was legit. I've been filling up at ESSO for years, partly because of the discount, I pass four ESSO services daily and I was under the impression that cheaper supermarket fuels are of a lower quality. While looking for something to back up the text, I found these posts:

It got me thinking and my questions are: what do you guys fill up your cars with, so-called quality fuels from BP, Shell, ESSO, supermarket fuel, or the premium stuff? And do you notice any difference between them?
In my own experience, my previous A4 B8 diesel didn't run well on fuel from Tesco, so I switched to ESSO all the time with the discount card, and after some years started using Millers diesel treatment and now Archoil. I've never tried the fuel additives with Tesco fuel.
I can also add to this I've tried all the premium fuels, and BP was by far the best in terms of getting more MPG and performance, without the addition of a fuel additive.
