Mechanics sometimes give bad advice based on prejudice.
They are equally able to be influenced by ‘popular opinion’.
In my life I have learned that following ‘popular opinion’ is hazardous. Rather I’d prefer to operate an engine in accordance with the manual.
You have to have a very good reason for deviating from the manufacturer’s instructions.
Mechanics used to tell me that using the mixture control “will not save money”, it’s dangerous, well why was the engine fitted with it?
From my point of view, revving an engine on the ground and leaning to clear unnecessary lead through using the wrong fuel is much more damaging to an engine.
If you use 100LL then using the mixture control is essential.
We have Avgas 91UL, it is a certified AVGAS that is an alternative to using Mogas, which is itself suffering from alcoholism, which is an alternative to using leaded fuel to avoid fouled plugs, and sticking valves.
