A 6 cyl being used at optimum speeds rather than up/down gearbox use will get near or equal smaller engines as power to weight comes into play, 6 doing less than 4 doing more basically
Of your cars era 50 mpg is good, my Insignia used to report 42 until it got to about 70k then one day it just started returning 50 and just kept getting better towards the end of my ownership of it with 54 regularly seen
I really think you are looking for something that isn't there tbh and you must appreciate when you go to forums there's always someone whose car achieves mystical magical figures, as an old mate said to me many years ago "isn't it funny how we always get the s**t cars?" basically other colleagues (I've a better description on them tbh) were deluded or lying, you will find these people everywhere you go they live perfect lives, nothing bad ever happens to them and they always leave the WC smelling of roses,
In addition to the fuel treatment I would have a look at which filters were fitted at the last service, you may find you have an old clogged fuel filter still or one of the brands that are cheap for a reason, if you can treat it to a set of Mann filters, Mann supply the makers so you're getting a genuine quality filter without it having Volvo stamped on it, one last one perhaps the petrol station you use has changed suppliers and the fuel isn't so good now, all these things need considering,
I still think at the end of it all you're expecting more than the car can return, it's 8 years old using ancient engine technology from a period where the masters were insisting engines not designed for modern things like dpf's, adblue, etc be fitted to them, in addition to the heavier safer car aspect Volvo builds,
If it runs smooth, idles smooth your only real option is to buy a full filter and oil kit from ECP and if you can't do it yourself find a good indy mechanic to fit the lot for you, at least then you'll have a benchmark of what it can't be,
Just type your reg number into ECP and select Mann filters each time and the correct oil grade for the car, if they've fitted 5/40 when it should be 0/30 this will mean your hot oil is thicker and making more drag on the engine so check the handbook for the correct one, garages are rife for using whatever they have in stock rather than the correct grade, premium labels doesn't mean better either, the QX oil although cheaper is good oil and probably something from Shell, Mobil, Exxon rebranded.

Thanks for the insightful post, I appreciate the effort and help.
I think you're probably mostly right in all honesty, I have a few reservations in that my golf mk7 was a 13 plate and the engine used in that was far better on fuel, granted the golf is probably a fair amount lighter.
Then again, comparing 2 completely different engines is a bit daft in the first place anyway so perhaps that's not the road of thinking to go down.
I'd hope a Volvo main dealer would service the car correctly but then again, another Volvo dealer I dealt with tried to sell me a car with an incomplete service history and 1 key, while telling me that's normal and acceptable for Volvo Selekt... before I told them where to shove it, so it's not like we can actually trust main dealers is it!
I think I will look into the filters and I will give some redex ago since I have a bottle of it in my garage anyway, may as well use it!
