Yours being a '93 is a cat1 maintenance schedule car;
7,500 - Oil Service
15,000 - Inspect.I
22,500 - Oil Service
30,000 - Inspection II
So if you follow the above pattern, at or about 127k you should be due for Oil Servive. Note you should be doing an oil change at the 1/2way point between the Oil Servs/Inspections. Some of the new issued bulletins are stating "at the 1/2 way point it's only neccesary to change the oil filter and top up the oil level PROVIDING the car is usings a hi quality synthetic oil"
