One thing to note is that a good quality fuel such as V Power will benefit the engine and injection system, it has additives that reduce carbon build up and help longevity.
I only ever run my cars on V-Power, knock sensors or not.
Me too, in the Morgan anyway
Also Lord Sward who is in car insurance told me that only Shell have tanks in all their garages that are completely sealed to moisture
