Car had little more power on supermarket diesel hope for the best on the rest
Car filled with Tesco diesel feels a lot more perkier so works in that respect. Miles per gallon I think slight improvement not much. The rest of it is internal so I hope it is doing what is says on the bottle.

STP Ultra
Its the first time I have used this product so will see how it works. The car already appears to be running smoother than before so will use it every 4000 miles as suggested from now on.
