The 2018 Subaru Crosstrek will need to use full synthetic 0W-20 motor oil. This vehicle came equipped with a 2.0L 4Cylinder across all trim levels and it will have a capacity of 4.6 US quarts when the filter is included. This vehicle will need to have it's oil change out every 7,500 miles but it will come equipped with an oil life monitoring system that will tell You when it's time to have it done. The oil drain plug will have a head size of 14mm and require 18 lbs-ft of torque to remove it using a torque wrench. If You don't have a torque wrench then a socket wrench will be perfectly fine as long as You have a 14mm socket.
