back when these motors were made you had a lot of zinc in the oils. Gub'ment got involved and saw that was good so they "fixed" it and now all the zinc is about gone.
Since you just did an earl change you can put
this stuff or something like it in there. Any high zinc oil additive is good. They run about $10 bucks
