Just had my E-/Type jag engine totally rebuilt. Added GP1. When first starting I get a “knocking” somewhere in the engine until the oil pressure comes up. I never remember getting that with conventional oils. Any advice? After pressure comes up with GP1 engine is smooth as silk. Am I doing damage?

Why use oil with zinc for old engines?
Hello Roger,
Here is what our expert Mark had to say regarding your question:
“Newer engines use roller lifters, where older engines use flat tappet lifters (solid and hydraulic), when oil manufacturers first removed the zinc from oils to help preserve catalytic converters older engines began to tear up the camshafts.
This was especially true on newly rebuilt classic car engines, as the little bit of cushion the zinc provided was no longer there increasing the wear on the camshaft and lifters.
In some cases early on, the camshaft lobes were nearly worn nearly completely off before the rebuilt engine got off the dyno.
Some people claim after break in of 1,000 to 3,000 miles the zinc additive is no longer needed, but we’ve always seen adding zinc additives as an insurance policy against valve train wear.”

Is this oil as good as Brad Penn? I have a 70 Z/28 with the original LT1 using a solid lifter cam that needs the zinc protection.

Is this syn oil good enough to break in 1960’s British engines? Jag,TR’s ,MG’S and the dozen’s of other Brit engines.
Hello,
Here is what our expert Mark had to say regarding your question:
“For most engine break ins on classic engines a high-zinc break in oil is a better choice to protect the valve train. (first 500-1000 miles)
Many enthusiasts also prefer to use conventional motor oils with zinc additives for the first oil cycle from 500 to 3,000 miles.
They claim standard oils allow the rings to break in and seal better, but we have never tested it, although we do prefer to always run some zinc additives in pre catalytic converter cars.”
