I changed the engine oil + filter last week - mileage 3,548 km (2,218 miles). Yes it it is early but with winter around the corner I thought I will change the oil. I did it myself. The oil drain access cover is easy to remove, the drain plug needs a 14mm socket. Use a new drain plug washer as it is a compression type washer. Love the easy access to the oil filter. I got the oil filter + drain plug from Subaru.
