I started using this product in my 54 F-100. The original engine, 238 ci y-block, OHV V-8. I believe that it has helped this old motor keep on keeping on.
I have been using the Z-ROD 10w-30 oil in my 1969 Mustang/351Windsor for several years and it keeps the engine very clean and gets good oil pressure in excessive heat at highway speeds. I am switching to the 10W-40 this spring because I'm doing more extended traveling miles and tend to run over 100 miles at 65+ mph before I give it a break.
I run the 10w40 Z-Rod oil in my John Deere Z960m commercial mower it does great, no issues whatsoever. I chose this oil over others due to the added protection for flat tappet cams and anti-corrosion properties.
Bottom Line
Yes, I would recommend this to a friend.

So far I love it, I run it in my cammed 2015 Camaro and it runs like a dream. Definitely worth it especially with the ams oil membership. You will not be disappointed!
This is the only oil for 66 AC cobra 351 Windsor and my 2017 ZL1
Bottom Line
Yes, I would recommend this to a friend.

Great oil for old cars. Drained oil for oil change and oil looked great probably could have continued using it for a few thousand more miles. But I’m old school and still like to change my oil every 3000 miles or once a year depending on what comes first for my classic cars.
