Oil Change on 2012 Subaru WRX

I sold the Infiniti G35 and replaced it with a 2012 Subaru WRX in February 2025. The Infiniti had just too many issues and had left me stranded a few times already, so I sold it to another enthusiast and bought a WRX. In May of this year, I also sold my Porsche Boxster. It was in great shape but I just needed one lesser car, so I stuck with the WRX since it was a 5-speed manual.

The WRX has a 5 speed manual with a short-shifter, had a tune from Cobb, Invidia headers and a Cobb intake. I have not researched the details of these modifications yet but I will and note them down in another post in the future.

I had driven it about 2500 miles and the oil change was now necessary to do. So this post describes how to do it. Sadly, I was in a rush and did not take enough pictures, but I have some as you will see.

Replacing PCV and Purge Valves

I described the Miata’s valve cover gasket replacement earlier. At the time I had not replaced the PCV valve, however, now that the car has aged further and received a code P0106, I chose to change both the PCV valve and the purge valve. This post describes the changes. I chose not to change the boost solenoid, which is also recommended for fixing the P0106 code.
