What kind of octane gas do I put in my 2013 Subaru wrx?
Just depends on the performance you want... The higher the octane the more combustion in the engine... The faster you go and cleaner the gas is. It should say in your manual what it recommends... Hope this helps you.
I would say though, if it was my car I would be putting 93 octane everytime.
Premium fuel 91 or 93 octane. Depends where you live and what is available.
