Thankfully, for as long as I have been driving, we no longer have to decoke our cars every few thousand miles these days as recommended in the handbooks of old cars of a certain age.
But when did this change happen?
Was it widely advertsised?
Did the fuel companies make a big thing of it? I imagine it was advances in fuel technology that brought this about.
I imagine it must have been wonderful news to hear you no longer had to do this dirty tedious job anymore ( it's hard to imagine anyone actually enjoying doing it).

Petrol sold today is completely different in chemical content to that sold back in the 1950's, 60's, 70's, etc.

It is a major reason why old technology engines today can run 'hot', or find hot starting more difficult than it used to be.

There are additives which make engines run cleaner, as well. Part of the save-the-world environmental changes [emissions, etc]

The above book makes for interesting [as well as definitive] reading concerning modern fuels and old vehicles. Worth reading many times, and attempting to understand, it explains a lot.
