Hiya,
Just had a read of that now, I hadn't really thought of T&D or Longlife, as I have usually just always had a service every 10k/year, sometimes with an extra oil change in between.
I only bought the Longlife III as I thought it was a good quality oil, not to use it for 20k Miles though, same rules would apply, the 10k/year service.
I don't know how to call up service info? How do I do this (highline dash)
Many thanks
