Same car. Personal preference. I use Millers, mainly for convenience. One bottle to a tankfull. Get mine from ScoobyMania in Nottingham, at a good price.

NF and others are probably as good/better/worse but mostly come in quantities that need to be measured into the tank.

Why not buy yourself a couple of bottles of each. I think the popular ones used by people on here are Millars which is easily available accross the country and NF available from Roger Clark Motorsport and others usually by post. Some people use Proboost. Do your own experiments using the same petrol and see what you think performs best and is most cost effective.
Having done all that I have stuck on NF (Nitrous Formula) having tried seven or eight other products.
