Synthetic Oil for 2012 Subaru Legacy

Asked by Apr 26, 2012 at 04:59 PM about the 2012 Subaru Legacy 2.5i Premium

Question type: Maintenance & Repair

Just recently picked up a 2012 Subaru Legacy Premium with the 2.5 engine to replace my old Outback wagon.  This time around I was thinking of converting to Synthetic oil to help improve gas milage and to strech out oil change intervals.

I was planning on making the change after the first oil change which is scheduled at 3,000 miles. Any thoughts as to running synthetic in the 2.5?  

1 Answer


Good choice running synthetic just make sure you use fully synthetic and not blended. On a new engine like that is prime time to do the change-over. Yes you may notice a small increase in gas mileage and you will notice faster warm-ups as well.
