Some might argue it doesn’t matter what you fill up with and from whom
I was informed by the head mechanic at Kia Linwood never to fill up the Sedona with Morrisons diesel.
My partner won’t go near Morrisons for fuel after having a couple of engine issues with her diesel Freelander. Her garage told her it was not an isolated incident and not to use their fuel. And I always thought that all supermarket diesel cane from the same refinery 🙄.
I always ran the Roadster on 98 Octane as I was convinced after the remap that it ran better. Ditto my 4/4 when it went onto throttle bodies....it did not like 95!
As far as my new toy....well I guess it ran on 80 octane in its day!
