I used the Millers for years, great job.

use the miller's myself mate and is goooooood

[marly]

millers for me too, does seem to smooth things out a bit, but could it just be a placebo effect?

[Hideous]

Only one I've tried was Millers, and it didn't do any harm.
I never bother now with anything.
Best thing for the diesel IMO, is a good long run at a steady "X" mph, as often as you can

[Big Sig]

Have tried them both and never noticed any difference. I even gave my remaining half bottle of sport 4 to Ditchp.

Every 6 weeks run the tank low and fill to the brim with BP-ULTIMATE DIESEL.

I chucked a Tesco own brand one in, bargain at £1.49p so I bought two.

[big rich]

im gonna try some millers with a full tank of bp ultimate and give it a blast (70mph) up the motorway....hopefully it gives it a nice clean out

Adding cleaner routinely is not cost effective. Occasional use of any injector cleaner probably won't do much harm or good, but whatever you like. I good long steady motor will probably do far more good IMO.
