Very important on initial startup to break in a cam.
I use comp cam additive part# 159.
And also if you want to keep a little zinc in your oil.The STP additive is 75% Zinc.

I run a MP cam and I use Bradd Penn break in oil with a bottle of GM EOS, and have never had any problems with cam wear.Actually I put the EOS in with every oil change You should be able to get the EOS at any GM dealership.

Good luck finding EOS anymore. Here in the Seattle area I was told by the dealership parts guys that it is discontinued. He showed me a list of dealerships for 100 miles and the meager quantity of EOS each one had left in stock.

Look up ZDDPlus. Its a relatively newcomer to the scene develeped specifically for the reduced ZN oils of today. The ppm in the little 4 oz bottle is 71,000.......yep 71,000. That boosts the level WAY up in a 5-6 quart fill (do the math).
There ARE safe oil choices too, some are synthetic--redline, amsoil, royal purple, some not like Brad Penn, and diesel oils like Delo and Rotella

“Motor oils are carefully balance by the formulator/manufacturer and tested to verify compliance with appropriate specifications. Adding aftermarket additives to these oils may upset this balance and the results may be unpredictable. If you trust the technology of the manufacturer, then it would be prudent to leave his formulation alone.” – Tom Schaefer, retired vice president of sales and marketing for Hatco Corporation. An unpredictable behavior of a motor oil with an aftermarket oil additive could lead to foaming tendencies as shown in this LINK CompSyn

Or the red bottle which has a bunch of zinc but is thinner than the blue bottle stuff.
