Driver side 1/2 way back under the along the edge.
On the 1993 Toyota Previa, the oil filter is located on the driver's side of the engine, near the bottom. It is positioned behind the engine's oil pan, making it somewhat accessible from underneath the vehicle. You may need to lift the vehicle to reach it easily, as it can be a tight space. Always ensure the engine is cool before attempting to replace the oil filter.
