OK the reason I inquired about the oil was because I saw that it was low after getting the "service" warning light was coming on intermittently, so that was the first thing i checked, but after getting the correct oil and bringing up to the correct level the " SERVICE " light is still coming on now and again, I remember this happening some time ago then it stopped and hasn't been on for months, I service my own car so have you chaps any Idea what could be causing this before I take it to the garage , cheers
