For the duration of a year I've always put in pennzoil 5w-30. I have heard a lot of good things about "synthetic oil" so I figured I would try the M1 5w-30 synthetic high mileage oil. I noticed my car exhaust sound increase... I love my car and I really want to know if changing to M1 synthetic was right? The last thing I want to do is blow my engine. I occasionally push my car to the limit but for the most part im good to her. I really would love to know if making the change was right, the car sounds more throaty. I hope that is a good thing.
What do you guys run for oil?
Did I make a good decision?
I own a 2002 wrx.
Thank you for your help!
