Thanks for the heads up on this. Regarding the diesel, it is well worth paying for a couple of consecutive fills of V-Power or BP Ultimate into a diesel every year especially if the car has been run on pure supermarket diesel that has no additives that are required to keep diesel healthy as well as the environment and our health. Visible smoke was completely eliminated and pollutants did drop on MOT. I know all D4-D loves V-Power.

Not sure it works for petrol though, I remember premium stuff made the Toyta petrol 1.5 smoke a bit for ages so never went back.
