Thank you 1800 1973

I'm generally skeptical of pouring something into the engine but Sea Foam has produced clearly beneficial results on a number of my vehicles. As to engine oil and zinc content, this has been discussed endlessly. My engine rebuilder commanded me to use a ZDDP additive which I buy from IRollmotors.
Recently, I came across a posting by an 1800 member who seems quite knowledgeable. He states that a NAPA oil, "Universal Fleet Plus" in a 15-40, or a Valvoline oil, "All Fleet Plus" contains what our older engines need.
Good luck and please post your progress.
