cheap dino, 5-30 IMHO. Don't start pushing it at all until after 500 mi. Then start adding light boost until 1K

you trusted your builder with $15,000 dollars already, why would you stop listening to him now?

A) he knows your clearances, and what weight of oil is required for proper lubrication
B) he likes the composition of that certain type of oil
C) he will have the best input on engine break-in, so ask him!

For my engine my builder and I elected to run the engine relatively hard, letting it see 4-8 psi of boost quite often, and lots of engine braking to seat the rings. We changed oil at 150, 300, and 1,000 miles. I now have 2,000 miles and will be switching to synthetic on the next change.

benw is on the right track. baby it and it WILL burn oil. the rings need cylinder pressure to push them into the cylinder walls. dont beat the piss out of it, but do run it under mild boost and vary the throttle position and load a lot.

i babied mine for the 1000 miles, with also some some what hard pulls and engine breaking to get the rings set. My builder also said to run cheap 5-w30 dino oil, then change at 100, 500, 1000 miles then at 1000 i could run any oil.
