Subaru Crosstrek GU

Naturally aspirated boxer with 2.0L — the Impreza/Crosstrek engine. Watch for valve spring recall on 2012-2014 models. Oil consumption on early examples (class action settlement). Significantly improved from 2015. Reliable everyday engine with no ambitions — does its job and stays quiet.
