not specialized oil - just use conventional (non-synthetic)
-Prime the oiling system, run conventional multi grade oil per engine's oil spec.
-Warm up, vary RPMs,gradually increase load and RPM's;
-Listen for noises, check for leaks, watch guages, evaluate engine build and install.
-drain the oil at 50 miles and 500 miles. Also check if there are re-torquing requirements.
-During the first 50 miles run partial throttle/ partial vacuum building to full throttle / full vacuum cycles in 3rd gear when engine is fulling warmed up ...to seat or 'work' the rings. Engine must be under some load, but not lugging or going above 2/3 max RPM.
-continue increasing RPM and pushing the engine over the first 1000 miles, but letting engine run and rev freely.
-After 1000 miles change oil and start 3000 mile interval with conventional oil.
-4000 miles switch to synthetic oil and determine best 'longer' interval
