After the Terraclean treatment a few weeks ago, I got the dealer to throw in some Forte fuel treatment and a Forte oil treatment in with oil change. No harm in a cleaner internal engine than a dirtier one...
Been getting some interesting motorway mpg results (measured from fixed junction to fixed junction with cruise set for whole journey):
London<M1>Leicester - 50mpg (60mph)
London<M4>Bristol - 50mpg (60mph)
London<M4>Bristol - 42mpg (70mph)
London<M40>Oxford - 42mpg (70mph)
All an improvement on the pre-treatment mpg.
Here we go again!
