Some people run a special break in oil. I just run what I'm going to run in the motor.

If it's a flat tappet cam, get something with a high ZDP content or use a break in oil additive specifically designed for flat tappet cams.

rotella T 15-40 and make sure to prime the motor first.

Honestly, I wouldn't even think of breaking in a flat tappet came without adding an EOS anymore. Even the "good" oils have cut back so heavily on the zinc content, you don't know what's what anymore.

got this from shell rotella site. i heard this is good oil, but by a diesel engine standpoint. quote,'1210 ppm zinc'. here is the site.

I just know Compcams says to use it, I have installed five cams in the last year and half without one failure.

like the others have said above, the oils today don't have the additives they used to. Add a quart of GM Engine Oil Supplement (EOS).

A lot of high end engine builders use Brad Penn oil for break in, like the NASCAR guys.

That being said, i've never had a problem breaking in a cam with the EOS, pre-lubing and making sure your engine fires the first time.

I run 15w40 rotella with a 4oz bottle of melling lube (1400ppm) from piston ring half on the cam at assemble and half in the oil pan never had a problem
