My BRZ has 12K miles on it. Been running Subarus synthetic. Just did an oil change with Royal Purple synthetic and a high flow performance filter.
I am amazed at the immediate noticeable difference in my car.
It is way smoother, revs much faster, and must have an additional 10-15Hp and torque.
How is this even possible with just an oil change? Is Subaru using sh** for oil??
All I can say is do it now. I used the recommended weight as per the owners manual and approx 5.7 quarts.
For $80 this has got to be the cheapest and best performance mod going.
My BRZ feels like a different car. Unreal.
