You should just use Fuelsave diesel though as it's more energy dense and has a greater typical cetane rating than V-Power according to Shell. Not to mention being 6p/litre cheaper and fresher / more likely to be blended to the current weather conditions.

I also wouldn't lose any sleep over adding Millers to a supermarket fuel. It's Euro4 compliant and intended for use with DPFs, can only improve the lubricity and detergent quality of whatever fuel you use and BMW could never determine that you'd added it. The stipulation not to use additives is sound advice in general as the cars are designed to run on regular fuel and it stops most people adding any random snake oil to their tanks which might not be suitable and cause more harm than good. Millers is not snake oil though and it will run better on it.
Just to piss on your parade quickly... V-Power absolutely has a HIGHER calorific value than fuelsave diesel, and a HIGHER cetane rating. Somewhere on another forum, a couple of years back, I posted the data sheet from Shell with all the figures on.

My pre-LCI 330d runs quieter and smoother on V Power, but no noticeable change in performance - which I have had in previous 4-pot cars.

Millers is good though. Stinks to high heaven, don't ever spill it on your clothes or in the boot because you'll never get rid of the smell - trust me, I know
