I've just had the last service on my 2 year service plan. Last year I supplied my own oil (longlife) but they told me at the time that they use longlife oil anyway now for T&D services. This year I decided not to supply my own oil and they've gone and filled it with the lesser stuff. I queried this and they said that they only use longlife on the longlife regime.
My father in law has the same service plan at the same dealer and after a bit of a stand off, they filled his with longlife oil!
I only do about 1000 - 2000 miles per year but it's the principal. The car only goes out about once or twice a month so i'm not unduly worried about engine wear. However, I want to challenge the dealer but be able to provide evidence if possible of the technical bulletin, which I believe came out a couple of years ago informing dealers that they should now fill with longlife oil for all types of service.
Can anyone point me in the right direction re this tech bulletin? copy / date / number etc.
