4,000 miles of Valvoline Restore & Protect On My Old Honda Did it work?

At over 300,000 miles I have a rattling noise at low RPM's, weak on the power, High oil consumption, and Blowby. Will Valvoline Restore & Protect work on my old 2005 Honda Accord LX. This is the first Oil change out of the 4 I will be doing. I will change the oil every 4k miles and update you on everything!
