Will Royal Purple SAE30 be ok for MTI H/C Package?

Do you know were the oil is going? Check your rocker arm bolt holes, ported heads remove the bump and oil can seep through the threads. Also check your pcv system, most people just vent the crank case into the atmosphere.

If you want something thicker, why not use Royal Purple's Racing 41? It's viscosity is more like a 10w40 and it works very well in hard driven LS1s.

This is the first I've heard of not using synthetic on a fresh bottom end. (Maybe have heard it but never paid attention until now.) I am putting my block together next week with all new bearings but using the stock crank, rods, and pistons. Should I be wary of using synthetic when it goes back together? I usually use Amsoil, weight depends on the time of year.
Sorry Pro Mouse, not trying to hyjack your thread, just caught my eye and am concerned.

Using breakin oils or normal oil will shorten the time it takes your rings to seat, but I have always followed GM's example in their more expensive flag ship cars and used the synthetic after the 1st oil change.

I never ran anything but M1 5w30 in my 98 Formula actually. I wasn't doing oil analysis back then. Although the engine seemed to like it, I had no consumption problems with it. (although the following owner reported that it started drinking oil like crazy for him)
