Hey Guys truce
I posted the information in good faith because I thought it might help someone that needed an oil change and was having problems finding a Merc Specialist that could be bothered as I was (now I have finally found one bit too late but never mind) I wasn't intending to kick off a fuss.
I think in future if I find anything useful (as in this and previous posts) instead of posting I will keep it to myself - we are supposed to be a club and as such helping each other with suggestions (helpful or not) we should act as a club.
