slj1 - overall what have you thought of the upgrade? - if you knew then what you know now would you do it again? Seriously considering this myself at present too.
Yup. I have one spare - bought one, went to fit it and found there already a connection on my car. Still brand new in the packaging. I'll have a look for it in the garage tomorrow
Thanks I see millers now list this as the replacement for the xfs - is this the stuff to go for? https://www.opieoils.co.uk/p-60214-millers-oils-xf-longlife-5w-50-full-synthetic-engine-oil-formerly-xfs.aspx
