Question:
Best Mobil 1 Oil for a 2012 Subaru WRX
I have heard many negative opinions of Mobil 1 (Extended Performance and original) having issues with shearing and issues with oil consumption in the Subaru WRX. I have run Mobil 1 full synthetic in a 1998 Dodge Neon in the past with amazing results, as well as in a 2007 Honda Civic Si. I did experience oil consumption in a 1989 Toyota Supra (turbo) which was considerably less of an issue with Valvoline full synthetic. My concern is that I now own a 2012 Subaru WRX and will be performing the first oil change. I live in Arizona where temperatures reach over 120° degrees in the summer. The owner’s manual requests that I use 5W-30 full synthetic, but I am curious if I should use your Mobil 1 0W-40 or your Mobil 1 Extended Performance 5W-30 for the best protection.

Answer:
While your vehicle is still under warranty, we recommend you follow the viscosity grade guidelines as stated in your owner’s manual. For your WRX, we recommend Mobil 1 5W-30, or for our ultimate in performance and protection, Mobil 1 Extended Performance 5W-30 to meet your performance needs.
