Is it old enough to be leaded...
It'll already be diluted, 50:1 or maybe (as my strimmer uses) 20:1. A litre of 20:1 in a 50 litre fill up is going to be 1020:1. 50:1 ends up at 2550:1.
Lead either in the orginal petrol or in the oil is likely to be more of an issue.
My very knowledgeable garage advises premium diesel every tenth refill.

I believe a mild anaesthetic gel might be of some help.
Is that the same "very knowledgeable garage" that also sells premium diesel - do they make more money that way?
They say that premium fuel contains additives that clean the injectors of a petrol or diesel engine - which in the case of a diesel results in finer droplets, less dribbling and therefore longer, less explosive combustion and so more power because of more complete combustion. Sort of Viagra for diesels!
Shame I didn't notice any difference - and I was looking out for one to make up for being fleeced of several pounds by the garage that hadn't labelled the pumps very well.
I've had two petrol cars that say to use 'Super' (98 octane) where available. On neither have I noticed any difference in performance or MPG. Now if the ignition timing is advancing to make use of the higher octane rating, the MPG should be better too. But despite checking them over a very long journey several times, no difference outside experimental error.
Do you anyone with a diesel vehicle who you have fallen out with ?.
If so, pour into their tank - all of it.
No they don't sell fuel. They mostly sort out faults that the main dealers send to them because they are stumped.
