The 15w 50 has 1200 ppm zinc. My engine was rebuilt in '97 and it has a lot of miles on it.
What is your suggestion
Thanks

Jerry I have not tried it yet but would be an ideal distance to rebuild all of then engines wear/stress surfaces with something like Archoil AR9300 ceramic coating.
Archoil AR9300
I have tried the Ceratec nanoceramic coating from Liquid Moly and on tear down could see/feel the glass like bearing surface created after idling the engine for 11 hours with the Liquid Moly Ceratec added to the motor oil.
I just learned about nano technology in lubrication a few months ago and got too busy to do all the research and testing that I hope to do in the future.
The test engine is a 325 cc Polaris ATV engine with a bad crank due to the prior owner blowing an oil cooler line and spinning the rod insert due to running it at high speed with no engine oil in it. All I did was hit the crank (still in the case) with emery cloth and replaced the rod with a used one and new Standard size inserts. After I started getting on the engine after 10 hours of idling it started to knock again but with that run time I was able to prove to myself the claims that Liquid Moly makes for their Ceratec nano ceramic coating for internal engine parts.
While the rough and I expect out of round rod bearing crank surface did start to eat into the bearing insert there is no way it would have rotated the 1,000,000 revolutions without the ceramic additive I am sure.
I did not know about the Archoil AR9300 at the time which I think may be better than Ceratec but the Ceratec proved the effectiveness of nano ceramic technology in my mind.
