What type of Oil to use to break in SR20?

[lightsource]

I've read several guides to breaking in an engine.
However I haven't read what type of oil to use, 10W40 is the only weight I've heard however I don't know what brands to buy.
If someone could I would appreciate if you could tell me what type of oils I should use breaking the engine in.
Thank you!

eh...any old cheap ass NON-synthetic oil will work for initial start up and break in. any "special" oil is just a sales gimmick. once you've started the motor and started driving change it after the first 50 miles. and then after 1000 swap to synthetic
