On a 1995 corvette the oil filter is located behind a shield at the bottom of the engine that looks to be held on by 4 bolts. This shield must be removed to locate the oil filter which will be obvious and located to the left side of the engine.
We just changed one on a 1995 Mercury Mystique 4/95. It was located on the transmittion. They tell us there are 2 for this model, other one is supposed to be located in Instrument panel but we couldn't find it.
