I'm using the millers additive, and shall say I mainly use Shell with only very occasional supermarket fuel.

I'll throw in my 'two pennies worth' 1st Jaguar diesel handbooks state do not use biodiesel. 2nd A pure white derv is near impossible to find at the pumps. Supermarkets thou doing nothing wrong as they have to conform to the relevant British standards blend high amounts of bio to fuels to keeps costs down. Unless your doing high speed driving each day high levels of biodiesel will eventually kill the DPF plus using a high content blend of bio will give less mpg. I always buy a branded quality diesel and not from the 'city diesel' pump plus ever 2nd tankful use a Millers diesel additive.
