Default 2018 WRX AMSoil Signature Series Interval

Hello all,

The thought occurred to me today that I may be making a mistake when it comes to oil change intervals. I am hoping someone can either put me at ease or steer me in the right direction. I picked up my 2018 WRX with 7k miles on it and I've been using AMSoil Signature Series 5W30 ever since. AMSoil states that this oil is rated for up to 25k miles on turbocharged motors. I have been changing every 7500 miles. I do some spirited driving occasionally but nothing too crazy. Are these intervals too long or is this okay? I've had no problems with the motor and I'm currently at 33k miles. I also have not done a UOA.
