Is this normal oil consumption?

IMO, changing the oil at 100 miles is excessive. I would change it before 1500, though. You'll see a lot of metal bits in the oil when it drains.

Also, it's not uncommon for an engine to burn oil during break-in. Half a quart over the first couple of thousand miles is not unheard of. After 4k or so, it shouldn't consume any excessive amount of oil.

Best of luck.

Probably, but this engine most likely wasn't rebuilt in a nice, clean assembly room by techs that do it every day. It was probably rebuilt in a corner of the shop by someone who rarely digs that deep into an engine.

500-750 miles, maybe even 1500, would probably be be good enough, but oil/filters are a lot cheaper (at least less inconvenient) than another engine rebuild. YMMV

Trust me change it at 100. All of those metal shavings, any dirt that fell in, lint from wiping parts ext will clog up that oil filter in no time and you will be running in bypass let anymore crud right through the engine unfiltered. You are also getting any of the assembly lube that they used out of the engine. Your not hurting anything by changing the oil more but you can hurt the engine by not changing it enough. Just run conventional for the break in period. This is the most critical period in the engines life, give it clean blood!

I am a professional engine builder (what I do for a living). When we build engines the oil change routine is after about 30 min of running (warm up cycle), 100 miles, then 1000 miles, there after normal intervals.

You need to remember also this is not a sealed engine when they get it. The tech doesn't care about cleanliness as much as he does about making flat rate.
