Z-ROD motor oil

In 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 Line
Yes, I would recommend this to a friend.

What's in your oil?

I'm amazed at how many car guys still don't know this. Conventional motor oil formulation has changed alot over the years. Do you wonder why your performance flat tappet is history? It's not the cam. The high pressure scrub requires ZINC to keep from murdering your valve train components. Specifically camshafts and valve lifters. That's why we use Z-Rod in all of our non-roller profile applications !!
Bottom Line
Yes, I would recommend this to a friend.

Muscle Car Motor Oil

I have a numbers matching 1969 Chevy Nova with a 396 CID engine with 375HP. That motor from the factory has solid lifters. Since car manufacturers stopped using solid lifters over 40 years ago the motor oils available today don't have enough Zinc Phosphorous to properly lubricate that kind of engine. My car is a street car, not a race car, and Z-Rod fills the bill for that better than any other oil I have found.
Bottom Line
Yes, I would recommend this to a friend.

The only oil that quiets 1.6L Miata lifters
By

I own a summer/track HPDE 1.6L Miata. I tried all the major brands of oil. The harder I drove, the louder the lifters would get. Even driving on the interstate. About 10 years ago I went to the PRI show in Indy. And had a nice conversation at the Amsoil booth with a very knowledgeable gentleman, explaining my situation. Since this car is driven hard and at high RPM, he suggested Z-ROD. Quieted it right down. No more lifter noise, even at startup. The oil analysis always come back great. Very low wear numbers. I could not be happier with Z-ROD 10W-30 in the Miata. Still on the original lifters. As far as I am concerned, noise equals wear. Where all the majors failed to quiet it down Z-ROD did the job. I will never use anything else in it.
Bottom Line
Yes, I would recommend this to a friend.
