Stopped All Previous Engine LeaksBy GLENN, a Verified Buyer from Orlando, FL on April 14, 2025After much research and thought I finally decided to switch to synthetic motor oil last year in my 1979 Corvette with a 350 crate engine with low mileage. There had been several oil leaks from the engine area but after running Amsoil Z-Rod, the leaks all stopped. I used it with the Wix oil filter. This year I did the annual oil change and still no leaks and the engine actually purrs differently from previously without the Amsoil. I am a believer.Bottom LineYes, I would recommend this to a friend.Was this review helpful?

Ultimate ProtectionBy ANTHONY, a Verified Buyer on October 11, 2024I use this oil in a Ford Cleveland 408 stroker and my 66 Mustang GT 289 A- code engine. After a refresh on the stroker, I literally could have reused the bearings. This is 550+ hp street engine that gets drove like it's supposed to. I use Amsoil in everything I drive. Also, broke in the 408 on the Dyno with the Amsoil break in oil.Bottom LineYes, I would recommend this to a friend.Was this review helpful?

Z-ROD motor oilBy AL, a Verified Buyer from Arkansas on January 08, 2024In the early days when I was building custom cars and street rods there weren't roller camshafts so the oil had ingredients to protect flat tappet camshafts, along came Catalytic converters so oil companies removed the Zink & Phosphorus from their oil as they destroyed Catalytic Converters!!!!!! Most all classic cars restored don't have a Catalytic Converter, but need an oil with Zink & Phosphorus tp protect there camshafts during break-in and after that as well!!! Z-Rod has these ingredients in it!!!!!Bottom LineYes, I would recommend this to a friend.Was this review helpful?
