NAPA Valve-Kleen?

I was getting some filters today and the NAPA guy was really pushing the Valve-Kleen oil additive. My 92 4.0l HO has 218,000 miles on it and is running pretty good, other than a few leaks to fix. Does anyone have any experience with it, and would it help or hurt?
Might not hurt. I used to work for NAPA so I am familiar with the name. I haven't personally used it, so I can't give you a fair evaluation of the product.

I do however usually use Seafoam for my inernal engine treatments.....(Great stuff, just beware of the exhaust stench and color while using it....)
