The key is just change it at 5,000 miles and no more. It’s that simple.
Wrong.
You cannot make a blanket statement like that.
10k OCI's have worked for me on a '13 3.5 and on my '17 3.5.
Feel free to look through all my old post if you like.
I sold the '13 at 147k.
The '17 is currently at 146k and will be staying around.
I just don't drive as much.
