Each to his own, but I go along with the "If it ain't broke, don't fix it" school of thought.
60+ mpg sounds good to me.
Once in a while. It’s good for an engine to be opened up, almost mandatory in a diesel IMHO.

Instructions on the bottle, just chuck it in when you fill up.Thanks, assuming that is the 250ml bottles that works out about £8-10 a litre of redex. I'll keep my eye out for offers.
What's the method for adding redex - add to a 1/4 tank than run car until fuel has nearly run out?
It is indeed. I've been advised that if the engine light comes on, as it does from time to time, it's the egr valve and the fix is to drive on the motorway in a lower gear, at say 3000 rpm, for half an hour or an hour. It may not clear immediately but it helps. I'm fortunate, I don't spend all my time in town so on my hour long commute I get the thing to motorway speed for a while.Once in a while.

That’s great but an Italian tune up once in a while is a good thing to do IMHO.

I've always wondered about the optimum speed for fuel economy - I imagine it needs to be calculated for every make/model, rather than one size fits all.
I think Redex. I use the stuff every few tankfuls, usually what I can get on special offer, Aldi do 2x Redex for £4 or £5.
‘Italian tune up.’
The mind boggles...

thats interesting , i can tell immediately if i put 95 or 99 octane in. The 99 makes a very big differenceTen years ago I was talking to a lorry driver who delivered fuel to petrol stations. It all comes from the same large storage tank, irrespective of the brand of petrol station it's delivered to. If there is some kind of brand specific additive it's added automatically when the lorry is filled up.
The cars manual should say what fuel to use. It's a bit like having a car designed for 95 octane (talking petrol now) and thinking it will be faster on 98...

I think driving to the speed limit on motorways might be safer for both yourself and the HGVs you are presumably forcing to overtake youI use normal petrol and never think of additives of any sort.
When driving, I go for maximum economy.
Accelerating slowly, reading the road to anticipate and keeping my maximum speed to 55 mph
on single carriageways and 65 mph on motorways.
My little Skoda can do 60+ mpg easily.
I don’t think Audi drivers like me, though.
Haven’t noticed any difference with premium diesel in my 535D or my previous diesel Octavia VRS. Both remapped.
I also put the odd bottle of Redex through mine.
You won't. The diesel is the same, it's only cleaning additives that are different in the premium ( I run the same car as you). A tankful of premium every 1000 miles or so is enough to keep the engine clean assuming the car is well maintained. I change the oil & filter every 3-5k at the most and also the air filter- I have done all the servicing and most of repairs on my cars for the last 30 odd years and run some cars to very high mileages. I work on site and some years have averaged over 50k. At each change I pour bottles of Forte Fuel System Cleaner and Turbo Cleaner into the fuel tank. Car is on 130k and runs perfectly. No major bills so far, fingers crossed.
