Back in the "Dark Ages", when I was younger (now almost 72 years young) and was running Nissan 200`s and Skylines etc., we used to avoid Supermarket Petrol like the plague. It was never suitable or desired for higher performance cars. They just would not run correctly on it and there was always fear of detonation and damage it could/would do.
Now running a car I have admired and desired for many years, S Type 2.5 V6, I have returned to the subject of Supermarket Petrol and whether I should use it or not. So where are we these days please. I am absolutely certain this will cause some debate and that there are members of this Forum that will have the knowledge and information to be able to discuss/advise on the subject at its current status. Currently I do not use Supermarket Petrol, based on old bias opinion.
Is today`s Supermarket Petrol good enough, fit enough, advanced enough, clean enough etc., etc, to be used in my beloved S Type?
Looking forward to replies and discussion on the subject.
(P.S. I am still waiting for some replies and advice on my submitted topic concerning Engine Code P0420 and unable to find corrective route. (in this Section, thanks)).
Best Wishes and Regards, John
