Booked my Vectra in for it's annual service in January.As it's having a full service this time round,there were one or two things I needed to point out to them to make sure that it was noted on the job sheet.When I asked about fully synthetic oil and any extra charge etc,(they put 10-40 semi in it last time),she told me that they had changed their oil policy and now routinely put in 0-30 fully synthetic as standard.Has anyone else heard of this?. FELIXX.
