Review: Nice product - I added this to my 1938 streetrod. SB pre 1975 Chevy V* and I was told that the valves needed a zinc additive. Price was good and I guess it is working, wont know until I tear it down which won't be far a couple of years. Unless something goes wrong..
Review: Good Value - Easy to store - Since it's an additive there is no way to know the effectiveness. It gives me peace of mind knowing my older 454 Chevy is getting the zinc and phosphorus it needs.
