I finally got a hold of a beautiful 2009 OB 3.0R Ltd. My questions is should I use premium gas (as recommended) - or reg would suffice; what are the main advantages of the premium octane level (90-93)?
So I bought a 2020 Subaru Onyx XT. Still have a half tank of gas, but going to a fill up probably this weekend. Just wondering about people thoughts on using premium versus regular unleaded gasoline. What about mid-grade? I know there are benefits to using premium gas.
