Synthetic Oil on aftermarket camshafts???
I recently experienced a lifter failure in my C6 Grand Sport, resulting in replacing the cam, lifters, springs, push rods, etc.
I'm hearing that when you go to an aftermarket camshaft, you should no longer use synthetic oil but use 10W-40 conventional oil instead.
Has anyone else heard of this???
I thought I'd throw it out there and see what the overall consensus is....
Thanks in advance!

you might also ask about using break in oil ( high zinc content oil ) for the first 500 miles, this is done when you rebuild an engine for camshaft break in

The high zinc break-in oil are essential for lubrication of not only the cam lobes but also the cam bearing surfaces and the crank bearings in a total engine rebuild. In your case where you replaced just the cam ( along with other related components ) it will have to go through the heat cycle to harden the lobe surface, typically running the engine at 2000 RPM’s for 20 minutes.
