Thank you for taking the time to contact Subaru of America, Inc. Congratulations on the purchase of your 2013 WRX.
For Subaru of America, Inc.'s maintenance recommendations for your 2013 WRX, please review the maintenance schedule on page 33 in the "Warranty and Maintenance" booklet. We are aware that the maintenance schedule on MySubaru sites for 2013 WRX models show 3,750 mile intervals. This has been brought to the attention of our Marketing Department.
We recommend maintenance services every 7,500 miles or 7.5 months, whichever comes first. Your dealer may recommend 3,750 mile intervals. If so, for all of the dealer maintenance recommendations in between ours, such as the 3,750 and 11,250 mile services, your dealer is always and only recommending an oil change. We recommend that you at least follow our minimum recommendations to keep all warranties intact and your vehicle in good operating condition.
Thank you for the opportunity to be of service.
