I did not want to hunt down zinc and a good additive package so Amsoil it is. Good performance and i am not wondering when my flat tappet cam will get wiped out...
Bottom Line
Yes, I would recommend this to a friend.

I have streetrods and antique cars. Z-Rod is a life saver in these older flat tappet engines. Wouldn't use anything else.

Excellent product that I use in my 54 Chev 1/2 Ton. 235 runs so smooth.

One of the bottles had a small leak as I noticed an oil stain on the outside of the box. The leak was small and not much oil came out. But before I could even contact Amsoil, I had already received a new replacement bottle! Now that’s great service!!! Thank you Amazon!!
Looked around, read many reviews, and spoke to a few other owners, and Z-Rod was always recommended. Now I see why-pulled the heads after 15k miles on my rebuilt 400 motor, and was amazed at the lack of wear. Z-Rod for life!
Bottom Line
Yes, I would recommend this to a friend.

Best oil on the market for flat tappet engines. I use it in my streetrod and have had absolutely no problems with cam lobe wear. I rebuilt engines and use this in all flat tappet engines I build with no problem to date.
