Synthetic Blend safe for breaking in a new engine?

[tigerclaws1318]

Would it be ok to use synthetic blend oil during the break in period on a new engine? Winter is right around the corner and was wondering if I should wait longer or could use it right away. I had the engine replaced due to oil consumption and I'm running castrol gtx right now. I normally use Mobil 1 on all my vehicles but I'm gonna wait till I put about 5k miles on it before switching over. So far only 400 miles on the new engine.

i did on my sr and im fine. i changed the oil at 500 miles the first time cuz it still had the assembly grease in it and what not. i used mobil one 5w30 i believe. now im using that weight in royal purple. everything is smooth sailing.
